Fig. 2 means the key diagram of the schematic configuration centered by the control module 110 of printing equipment 100.Control module 110 has: for the HPI from main frame 200 input image data ID (IF) 112; View data ID based on via HPI 112 inputs carries out the master control part 120 for the predetermined calculation process of image printing; Paper supply motor 172 is driven to the paper supply motor driver 114 of controlling; Print head 140 is driven to the head driver 116 of controlling; Carriage motor 132 is driven to the carriage motor driver 118 of controlling; The main interface (IF) 119 that connects respectively each driver 114,116,118 and paper supply motor 172, print head 140, carriage motor 132.

Master control part 120 comprises the ROM126 that carries out the RAM124 of the CPU122 of various calculation process, temporary transient storage, unwind and/or data and the program of storage CPU122 execution etc.The various functions of master control part 120 are read into the program of storing in ROM126 on RAM124 and carry out and realize by CPU122.In addition, master control part 120 can possess circuit, and the circuit that at least a portion of the function of master control part 120 also can possess by master control part 120 carries out work based on this circuit structure to be realized.

Master control part 120 is when obtaining view data ID via HPI 112 from main frame 200, based on view data ID, carry out image spread processing, colour switching processing, mass colour resolution process, the such calculation process for printing of halftone process, from any nozzle of print head 140, discharge China ink thus, or, generate regulation and discharge the black nozzle selection data of the amount of how many degree (driving signal to select data), based on driving signal to select data etc. to each driver 114,116,118 output control signals.In addition, the content for each calculation process of printing of carrying out due to master control part 120 is known item in the technical field of printing equipment, so in this description will be omitted.Each driver 114,116,118 outputs are for driving respectively the driving signal of paper supply motor 172, print head 140, carriage motor 132.For example, 116 pairs of print heads of head driver 140 are supplied with reference clock signal SCK described later, latch-up signal LAT, are driven signal to select signal SI&SP, channel signal CH and drive signal COM.Print head 140 has the control part 150 consisting of an interface (IF) 142 and circuit, the on-off controller 160(aftermentioned that control part 150 comprises) based on carrying out work via an interface 142 from the various signals of control module 110 inputs, carry out thus from the China ink of nozzle and discharge.In addition, part or all of the function of a control part 150 also can realize by software.Paper supply motor 172 and carriage motor 132 carry out work according to the driving signal of supplying with from control module 110.Thus, realize and on printed medium PM, form the printing treatment of image.

Fig. 3 means the key diagram of an example of the various signals of supplying with to print head 140.Driving signal COM is for driving the signal of the nozzle actuators that is arranged at print head 140.Driving signal COM is as the driving pulse PCOM(driving pulse PCOM1 to PCOM4 of least unit (unit driving signal) that drives the driving signal of nozzle actuators) continuous signal in time series.The group of these 4 driving pulse PCOM of driving pulse PCOM1 to PCOM4 is corresponding to 1 pixel (printed pixels).

Each driving pulse PCOM consists of voltage trapezoidal wave.The rising part of each driving pulse PCOM is for expanding the volume of the air chamber being communicated with nozzle, to suck the part of China ink (if considering to be also called suction meniscus from black discharge face), and the sloping portion of driving pulse PCOM is for dwindling the volume of air chamber, to extrude the part of China ink (if considering also can be called and extrude meniscus from black discharge face).Therefore, by driving nozzle actuators according to driving pulse PCOM, thereby discharge China ink from nozzle.

In driving signal COM, the waveform of driving pulse PCOM2 to PCOM4 (voltage increase and decrease slope and/or peak value) is mutually different.If be supplied to the waveform difference of the driving pulse PCOM of nozzle actuators, the extrusion capacity of the soakage of China ink and/or suction velocity, China ink and/or extruded velocity are different, thus discharge rate (being the size of the ink dot) difference of China ink.By selecting one or more driving pulses PCOM to be supplied to nozzle actuators, can form the ink dot of all size from driving pulse PCOM2 to PCOM4.In addition, in the present embodiment, drive signal COM to comprise the driving pulse PCOM1 that is called as micro-vibration.The in the situation that driving pulse PCOM1 not extruding only sucking China ink, for example, in the situation that suppress the tackify of nozzle and use.

Drive signal to select signal SI&SP to select to discharge black nozzle and the connection that determines to connect to the driving signal COM of nozzle actuators signal regularly.Latch-up signal LAT and channel signal CH input and based on driving signal, select signal SI&SP to make the signal that drives signal COM to be connected with the nozzle actuators of print head 140 after the corresponding nozzle selection data of whole nozzles.As shown in Figure 3, latch-up signal LAT and channel signal CH are and the signal that drives signal COM to synchronize.That is, latch-up signal LAT regularly becomes the signal of high level accordingly with driving the beginning of signal COM, and channel signal CH regularly becomes the signal of high level accordingly with the beginning that forms each driving pulse PCOM that drives signal COM.According to latch-up signal LAT, start the output of a series of driving signal COM, according to channel signal CH, export each driving pulse PCOM.In addition, reference clock signal SCK is for be sent to the signal of print head 140 using driving signal selection signal SI&SP as serial signal.That is, reference clock signal SCK is discharging from the nozzle of print head 140 signal using the decision of black timing.

Fig. 4 means the key diagram of structure of the on-off controller 160 of print head 140.On-off controller 160 is structured in a control part 150 of print head 140, will drive signal COM(driving pulse PCOM) be supplied to nozzle actuators 169.On-off controller 160 has: preserve the shift register 162 that drives signal to select signal SI&SP; The temporary transient latch circuit 164 of preserving the data of shift register 162; The output of latch circuit 164 is carried out level conversion and is supplied to the level translator 166 of selector switch 168; With the selector switch 168 that driving signal COM is connected with nozzle actuators 169.

Shift register 162 is selected signal SI&SP by input drive signal successively, according to the input pulse of reference clock signal SCK by stored region successively one-level displacement backward.In addition, to the driving signal of shift register 162, select the input of signal SI&SP, according to above-mentioned timing signal PTS, carry out.Driving accordingly signal to select after signal SI&SP is stored in shift register 162 with nozzle number, latch circuit 164 carries out breech lock according to the latch-up signal LAT being transfused to each output signal of shift register 162.The signal that latch circuit 164 is preserved is converted to and can be switched to the selector switch 168 of next stage the voltage level of (on/off) by level translator 166.With output signal by level translator 166 and nozzle actuators 169 corresponding to closed (becoming connection status) selector switch 168, the connection that drives signal to select signal SI&SP regularly and drive signal COM(driving pulse PCOM) be connected.In addition, after having inputed to latched circuit 164 breech locks of driving signal selection signal SI&SP of shift register 162, the next signal that drives selects signal SI&SP to be input to shift register 162, regularly correspondingly upgrades successively the save data of latch circuit 164 with black discharge.According to this selector switch 168, by nozzle actuators 169 from driving signal COM(driving pulse PCOM) disconnect, the voltage before the input voltage of this nozzle actuators 169 is also maintained and is about to disconnect.In addition, the symbol HGND in Fig. 4 is the ground terminal of nozzle actuators 169.

As shown in Figure 2, print head 140 has the thermistor 144 of the temperature that detects print head 140, and a control part 150 of print head 140 comprises based on carried out restriction by the detected temperature of thermistor 144 discharges from nozzle the discharge limiting unit 152 that black China ink is discharged work limit.Fig. 5 is the key diagram of the relation of the China ink discharge work of conceptual expression print head 140 and the temperature T of print head 140.Conceptually in Fig. 5 be illustrated in one end (starting position) while the balladeur train 130 that makes to have print head 140 along main scanning direction from printed medium PM and move with the highest resolution of printing equipment 100 and carry out continuously in the situation (that is, carrying out the situation of black discharge work in whole printed pixels of being determined by this highest resolution) of black discharge work 130 the distance L of position and the relation of the temperature T of print head 140 from starting position to balladeur train to the other end.Carry out from nozzle, discharge black China ink discharge work during, because of the various elements from headed by nozzle actuators and the heat of drive circuit, the rising of the temperature of print head 140.Therefore, as shown in Figure 5, the temperature of print head 140 from the initial temperature Ti(China ink of starting position is discharged end-of-job through equilibrium temperature during the sufficient time) along with the distance L of the black discharge work of continuous execution becomes large and rises.On the other hand, do not carry out black discharge work during, the temperature of print head 140 declines to initial temperature Ti.In addition,, in Fig. 5, although the relation of distance L and temperature T is shown as to linearity for convenient, the relation of distance L and temperature T according to the translational speed of the structure of print head 140 and/or balladeur train 130 and different, may not be also linear sometimes.

In the present embodiment, preset the ceiling temperature Tth of the normal operation that can guarantee print head 140.The heat resisting temperature of each parts (various elements and/or circuit) of ceiling temperature Tth based on forming print head 140 is, heat resisting temperature of the bonding agent that the installation of each parts is used etc. and determining.Discharge limiting unit 152(Fig. 2 of print head 140) carry out restriction and discharge black China ink discharge work limit from nozzle, so that the temperature of print head 140 is no more than ceiling temperature Tth.Specifically, when the temperature by the detected print head 140 of thermistor 144 reaches ceiling temperature Tth, discharge limiting unit 152 the driving signal selection signal SI&SP of the selection China ink discharge nozzle of supplying with from control module 110 is changed to and represents not discharge black signal from whole nozzles.Thus, select the content of signal SI&SP regardless of the driving signal of supplying with from control module 110, discharge black China ink discharge work all stop from nozzle, the temperature of print head 140 declines.Discharge limiting unit 152 after having started black discharge work limit, when the temperature by the detected print head 140 of thermistor 144 drops to predetermined recovery temperature Tr(Fig. 5) time, separate ink removing and discharge work limit.Recovery temperature Tr is more than initial temperature Ti and be less than in the scope of ceiling temperature Tth and preset.Recovery temperature Tr also can be identical with initial temperature Ti.By the China ink so being undertaken by discharge limiting unit 152, discharge work limit, can avoid because of the excessive temperature rising initiating failure of print head 140 or print bad.In addition, the China ink being undertaken by discharge limiting unit 152 is discharged work limit not necessarily to be needed by utilizing the method for the temperature detection result of thermistor 144 to carry out, so long as can avoid the temperature of print head 140 to surpass the method for the such China ink discharge work of ceiling temperature Tth, can carry out by other any methods.

In the present embodiment, in addition, based on ceiling temperature Tth, set continuous printing upper distance limit Lth(with reference to Fig. 5).Continuous printing upper distance limit Lth be in the situation that under the condition that the temperature of print head 140 the most easily rises, carry out the situation of black discharge work, distance L that the temperature of carrying out continuously black discharge work print head 140 with the highest resolution of printing equipment 100 reaches ceiling temperature Tth.In addition, if the translational speed of balladeur train 130 determines that balladeur train 130 moves the required time of continuous printing upper distance limit Lth and also just determined, so continuous printing upper distance limit Lth also can be taken as in the situation that the temperature of carrying out continuously black discharge work print head 140 with the highest resolution of printing equipment 100 reaches the time of ceiling temperature Tth.

A-2. printing treatment:

Fig. 6 means the flow chart of the flow process of the printing treatment of being undertaken by printing equipment 100.The printing treatment of being undertaken by printing equipment 100 is the processing with the corresponding image of view data ID in printed medium PM formation of the view data ID based on from main frame 200 inputs under the control of master control part 120.In addition, thus because printing equipment 100 is for forming the ink-jet printer of ink dot group printing images by discharging China ink on printed medium PM, so in other words " image " also can be called " ink dot group ".

First, master control part 120(Fig. 2 of printing equipment 100) obtain the width W m(step S110 of the main scanning direction of the printed medium PM using along printing treatment), judge printed medium width W m whether at above-mentioned continuous printing upper distance limit Lth(with reference to Fig. 5) below (step S120).Master control part 120 obtains the printed medium width W m that printed data (print command) comprises.Or master control part 120 also can be carried out actual measurement to printed medium PM and be obtained printed medium width W m.Or master control part 120 also can obtain to be utilized printed medium width W m that printed data (print command) comprises and printed medium PM is carried out to actual measurement resulting printed medium width W m and the printed medium width W m that calculates.At printed medium width W m, be continuous printing upper distance limit Lth following in the situation that (step S120: be), master control part 120 is carried out common printing treatment (step S130).

Conventionally printing treatment is following processing: the balladeur train 130 that makes to have print head 140 on one side by repeatedly carrying out is carried out to main scanning toward direction continuous moving with the corresponding China ink of view data ID and discharged and be operated in that printed medium PM is upper to be formed the work of image and do not carry out China ink and discharge and make balladeur train 130 return to main scanning the transportation work (subscan) that initial position that direction moves to initial position returns to work and carries printed medium PM to sub scanning direction, thus on printed medium PM printing and the corresponding image of view data ID.In addition, in the common printing treatment of the present embodiment, be made as by 1 image formation work and form for the image of unit region (be the whole width W m of printed medium PM and be the region of the nozzle rows length of print head 140 along the length of sub scanning direction along the width of main scanning direction) with regard to finishing.Therefore, the conveying capacity of the printed medium PM of subscan is to measure accordingly with nozzle rows length.In addition the formed image in ， unit region consists of a plurality of scanning fields (line being formed by a plurality of ink dots of arranging along main scanning direction).

As shown in Figure 5, at printed medium width W m, be that continuous printing upper distance limit Lth is following in the situation that, even if spread all over the whole width of printed medium width W m while making balladeur train 130 carry out image formation work to main scanning toward direction continuous moving, the temperature T of print head 140 can not reach ceiling temperature Tth yet.In addition, carry out initial position return work or transportation work during, owing to not carrying out black discharge work, so the temperature of print head 140 declines.Therefore, even if carry out common printing treatment as described above, also can avoid the temperature that print head 140 occurs to surpass the situation of ceiling temperature Tth, and can finish to form for the image of printed medium PM integral body.In addition,, in common printing treatment, for the image formation work of constituent parts region, be equivalent to the 1st image formation work in technical scheme.

On the other hand, in the situation that printed medium width W m is larger than continuous printing upper distance limit Lth (step S120: no), master control part 120 is carried out and is cut apart printing treatment (step S140).Fig. 7 means the flow chart of the flow process of cutting apart printing treatment.In addition, Fig. 8 means the key diagram of the summary of cutting apart printing treatment.In Fig. 8, illustrated and represented that R, the G of each pixel, B value are (0 having inputted from main frame 200,0,0) the view data ID(of the image of preliminary dimension, the view data corresponding with monochromatic picture black) situation under the summary of cutting apart printing treatment carried out by printing equipment 100 based on this view data ID.In the situation that printing equipment 100 has been inputted to the view data ID corresponding with monochromatic picture black, when carrying out image formation work, owing to discharging black China ink discharge work upper execution of whole printed pixels (by the definite pixel of the printed resolution along main scanning direction and sub scanning direction) from the nozzle of print head 140, so meet the condition that the temperature of print head 140 the most easily rises.In addition, at Fig. 8 (a), to Fig. 8 (d), the image labeling list hachure forming by illustrated work is represented, the image labeling crosshatch by forming before illustrated being operated in is represented (after same figure in too).

First, master control part 120 is carried out the 1st image formation work PA1(step S210).As shown in Figure 8 (a), while the 1st image formation work PA1 makes to have the balladeur train 130 of print head 140 to the work of the main scanning formation of the region AR1 on printed medium PM the 1st printing images PI1 toward direction mobile width Wp1.In addition, in Fig. 8 (a), at symbol " PA1 ", mark parenthesized sequence number " (1) " below, this parenthesized sequence number mean the 1st image formation work PA1 be the 1st image formation work PA1 corresponding with which unit region (after same figure in too).In the present embodiment, by the 1st image formation work PA1, finish the image formation for the part of the width W p1 in unit region.Therefore,, in the printing treatment that the view data ID that is the image of (0,0,0) in R, G, B value based on representing each pixel carries out, the 1st printing images PI1 forming by the 1st image formation work PA1 is monochromatic picture black.At this, the width W p1 along main scanning direction of region AR1 is set at below continuous printing upper distance limit Lth.Therefore,, although the temperature T of print head 140 is because the 1st image formation work PA1 rises, can not reach ceiling temperature Tth.In addition, the length along sub scanning direction of region AR1 is the length identical with the nozzle rows length of print head 140.

Then, master control part 120 is carried out the ST(step S220 that quits work).As shown in Figure 8 (b) shows, the ST that quits work is the work of the scheduled time that on the predetermined stop position on printed medium PM, the mobile halted state of balladeur train 130 maintained.Now, certainly do not carry out black discharge work yet.In addition, mobile halted state refers to the state that balladeur train 130 does not change in fact along the position of main scanning direction.That is, the movement of said balladeur train 130 here does not comprise positive micro-vibration of moving the balladeur train 130 while controlling of not carrying out balladeur train 130.In the present embodiment, the stop position quitting work in ST is the position (, with the main scanning of the 1st printing images PI1 forming by the 1st image formation work PA1 toward position corresponding to the borderline phase of direction side) of the balladeur train 130 of the 1st image formation work PA1 while finishing.In the ST that quits work, the time that balladeur train 130 maintains mobile halted state is redefined for and enough makes the temperature of print head 140 from ceiling temperature Tth, drop to the time of initial temperature Ti.Therefore, when the ST that quits work finishes, when the ST that no matter quits work starts, the temperature of (, when the 1st image formation work PA1 finishes) how, and the temperature of print head 140 all can drop to initial temperature Ti.

Then, master control part 120 is carried out the 2nd image formation work PA2(step S230).As shown in Fig. 8 (c), while the 2nd image formation work PA2 region AR2 on printed medium PM that is the balladeur train 130 that makes to have print head 140 from the stop position quitting work ST before to main scanning toward direction mobile width Wp2 forms the work of the 2nd printing images PI2.In the present embodiment, by the 2nd image formation work PA2, for the image of the part of the width W p2 in unit region, form and finish.Therefore,, in the printing treatment that the view data ID that is the image of (0,0,0) in R, G, B value based on representing each pixel carries out, the 2nd printing images PI2 forming by the 2nd image formation work PA2 is monochromatic picture black.At this, the width W p2 along main scanning direction of region AR2 is set to below continuous printing upper distance limit Lth.In addition, as mentioned above, by the ST that quits work before the 2nd image formation work PA2, in the zero hour of the 2nd image formation work PA2, the temperature of print head 140 has dropped to initial temperature Ti.Therefore,, although the temperature T of print head 140 is because the 2nd image formation work PA2 rises, can not reach ceiling temperature Tth.In addition, the width W p2 along main scanning direction of region AR2, can be identical with the width W p1 along main scanning direction of region AR1, also can be different.The length along sub scanning direction of region AR2 is the length identical with the nozzle rows length of print head 140.

Then the main scanning that, whether master control part 120 judgement balladeur trains 130 have arrived printed medium PM is toward direction side one end (step S232).In the situation that be judged to be main scanning that balladeur train 130 not yet arrives printed medium PM toward direction side one end (step S232: no), master control part 120 is carried out the ST(step S220 that quits work once again) and the 2nd image formation work PA2(step S230) group, carry out once again the judgement of step S232.Like this, master control part 120 is carried out the group of ST and the 2nd image formation work PA2 that quits work repeatedly, until be judged to be main scanning that balladeur train 130 arrived printed medium PM toward direction side one end.The group of quit work ST and the 2nd image formation work PA2 now, similarly carries out with the group of quit work ST and the 2nd image formation work PA2 of above-mentioned the 1st time.The position of the balladeur train 130 when the 2nd image formation work PA2 of the stop position quitting work in ST in addition, before being finishes.In addition, the mobile halted state quitting work in ST is held time so long as enough make the temperature of print head 140 drop to time of initial temperature Ti, can be at every turn identical, and also can be at every turn different.Similarly, the width W p2 along main scanning direction of the region AR2 in the 2nd image formation work PA2, so long as below continuous printing upper distance limit Lth, can be at every turn identical, also can be at every turn different.Even if so repeatedly carry out the group of quit work ST and the 2nd image formation work PA2, the temperature T of print head 140 can not reach ceiling temperature Tth yet.

When having carried out 1 time or repeatedly having quit work the group of ST and the 2nd image formation work PA2, be judged to be main scanning that balladeur train 130 arrived printed medium PM toward direction side one end (step S232: be).Now, as shown in Fig. 8 (c), the image of 1 unit region forms and finishes.In this case, master control part 120 judgements form whether finish (step S240) for the image of the Zone Full of printed medium PM.Form still in unclosed situation (step S240: no) being judged to be image for the Zone Full of printed medium PM, master control part 120 is carried out and is not carried out China ink and discharge the main scanning that makes balladeur train 130 move to printed medium PM and return the transportation work (subscan) (step S250) that the initial position of direction side one end returns to work and printed medium PM is carried to sub scanning direction, as shown in Fig. 8 (d), using next unit region, (in the example of Fig. 8 (d), being the 2nd unit region) is as object, carry out the 1st image formation work PA1(step S210) later processing.The conveying capacity of the printed medium PM of subscan is to measure accordingly with nozzle rows length.Such processing is carried out repeatedly, when being judged to be image for the Zone Full of printed medium PM, forms (step S240: be) while having finished, and cuts apart printing treatment and finishes.

As described above, the printing equipment 100 of the present embodiment, in the situation that printed medium width W m is larger than continuous printing upper distance limit Lth, carries out and cuts apart printing treatment (Fig. 7).In cutting apart printing treatment, first, while carry out making balladeur train 130 to move the 1st image formation work PA1 of region AR1 formation the 1st printing images PI1 on printed medium PM to main scanning toward direction.Then, carry out N time (N is more than 1 integer) while the predetermined stop position on printed medium PM maintains the mobile halted state of balladeur train 130 ST and make balladeur train 130 move the group of the 2nd image formation work PA2 of region AR2 formation the 2nd printing images PI2 on printed medium PM to main scanning toward direction from the stop position quitting work ST before of quitting work of the scheduled time.For example, as illustrated in Fig. 8, in the situation that printed medium width W m is larger and be below 2 times of continuous printing upper distance limit Lth than continuous printing upper distance limit Lth, by carrying out successively 1 order 1 image formation work PA1,1 ST that quits work, 1 order 2 image formation work PA2, the image of 1 unit region forms and finishes.In this case, the 1st image formation work PA1 is equivalent to the 1st formation work in technical scheme, and the 2nd image formation work PA2 is equivalent to the 2nd formation work in technical scheme, and the ST that quits work is equivalent to the adjustment work in technical scheme.At this, from Fig. 8 (c), even R, G, B value based on representing each pixel are (0,0,0) printing treatment that the view data ID of the image of preliminary dimension carries out, the minimum region of the brightness of the 1st printing images PI1 with by N(N=1 in the example of Fig. 8) N the region that the 2nd printing images PI2 brightness is separately minimum that order 2 image formation work PA2 form, be also on main scanning direction, to repeat and do not repeat on sub scanning direction.In addition, because R, G, B value based on representing each pixel are (0,0,0) the formed image of view data ID (ink dot group) of the image of preliminary dimension is generally the same black image (monochromatic picture black), so the brightness in each region of image is identical in fact.But, also can the image being formed by the 1st printing images PI1 and the image being formed by the 2nd printing images PI2 be formed a part of overlapped, in this case, in the repeat region of each image, because dot density (so-called dutycycle) is low, so high with other regions (non-repeat region) phase specific luminance.Therefore, the minimum region of brightness of the image forming by each above-mentioned image formation work, in the situation that each image does not refer to the Zone Full of image with other the doubling of the image, in the situation that each image and the overlapping non-repeat region that refers to image of other an image part.In addition, a plurality of image-regions repeat on main scanning direction, mean the whole overlapping straight line that is parallel to main scanning direction existing with a plurality of image-regions, mean that the position along sub scanning direction of a plurality of image-regions at least a portion is separately identical.In addition, a plurality of image-regions do not repeat on sub scanning direction, mean do not exist with a plurality of image-regions at least 2 overlapping straight lines that are parallel to sub scanning direction, mean that the position along main scanning direction along the position of main scanning direction and a part for other image-regions of each several part of an image-region is different.For example,, in the example shown in Fig. 8, because the 1st printing images PI1 and the 2nd printing images PI2 do not have overlapped part, so repeat on main scanning direction and do not repeat on sub scanning direction.The printing equipment 100 of the present embodiment, owing to can carrying out the above-mentioned printing treatment of cutting apart, even so be (0 in R, G, the B value as based on representing each pixel, 0,0) temperature of the such print head 140 of printing treatment that the data ID of image is carried out easily rise and printed medium width W m than in the large situation of continuous printing upper distance limit Lth, also can avoid the temperature of print head 140 to reach ceiling temperature Tth, and the image of realizing for printed medium PM integral body form.That is, the printing equipment 100 of the present embodiment, regardless of the content of image and/or the size of printed medium PM of printing object, the image that can both realize for printed medium PM integral body forms.

In addition, that at the printing equipment 100 by the present embodiment, carries out cuts apart in printing treatment, although the image of constituent parts region forms by image formation work repeatedly, but because each image formation work is carried out as predetermined, so it is bad can not make suddenly as the temperature detection result based on thermistor 144 in the past printing work that the printing of image occurs stopping.

In addition, that at the printing equipment 100 by the present embodiment, carries out cuts apart in printing treatment, because the stop position of the balladeur train 130 in ST that quits work is the 1st image formation work PA1 or the 2nd image formation work PA2 before positions while finishing, so avoided between the 1st image formation work PA1 and the 2nd image formation work PA2 afterwards, the unnecessary movement of balladeur train 130 between the 2nd image formation work PA2 and the 2nd image formation work PA2 afterwards, can suppress the increase of required time of printing treatment and the increase of power consumption.

In addition, the printing equipment 100 of the present embodiment, is continuous printing upper distance limit Lth following in the situation that at printed medium width W m, carries out common printing treatment.That is, in this case, do not carry out quit work ST and the such work of the 2nd image formation work PA2 cut apart in printing treatment.Therefore, in this case, can suppress the printing treatment increase of required time.

In addition, printing equipment 100, performed the 1st image formation work PA1 and number of times and the position on printed medium PM (region AR1, the AR2) of the 2nd image formation work PA2 while cutting apart printing treatment by decision, based on them, come divided image data ID(or printed data), data after utilization is cut apart, can carry out the printing treatment of cutting apart as described above.

B. the 2nd embodiment:

Fig. 9 means the flow chart of the flow process of cutting apart printing treatment of the 2nd embodiment.In addition, Figure 10 means the key diagram of the summary of cutting apart printing treatment of the 2nd embodiment.Figure 10 and Fig. 8 are same, show and represent that R, the G of each pixel, B value are (0 having inputted from main frame 200,0,0) the view data ID(of the image of preliminary dimension, the view data corresponding with monochromatic picture black) situation under the summary of cutting apart printing treatment carried out by printing equipment 100 based on this view data ID.The 2nd embodiment cut apart printing treatment and the 1st embodiment is same, be the printing treatment (with step S140) that (the step S120 of Fig. 6: no) carries out in the situation that printed medium width W m is larger than continuous printing upper distance limit Lth.In addition, below, centered by the difference of the 2nd embodiment and above-mentioned the 1st embodiment, describe, about with the 1st embodiment something in common, suitably description thereof is omitted (the 3rd embodiment too later).

First, master control part 120(Fig. 2 of printing equipment 100), as shown in Figure 10 (a) shows, carry out the 1st image formation work PA1(step S210).The 1st image formation work PA1 of the 1st image formation work PA1 and the 1st embodiment similarly carries out.The width W p1 along main scanning direction that forms the region AR1 of the 1st printing images PI1 by the 1st image formation work PA1 is set at below continuous printing upper distance limit Lth.Therefore, the temperature T of print head 140, although because the 1st image formation work PA1 rises, can not reach ceiling temperature Tth.

Then, master control part 120 is carried out and is returned to work MA(step S222).As shown in Figure 10 (b), the work MA of returning is that the work that direction moves predetermined amount of movement is returned to main scanning in the position while making balladeur train 130 finish from image formation work (in this case the 1st image formation work PA1) before without image formation work (black discharge work).In the present embodiment, the balladeur train 130 returning in work MA returns the amount of movement of direction to main scanning, be until return with the main scanning that is formed with the region (in this case region AR1) on the printed medium PM of image in image formation work before the position that the borderline phase of direction side is corresponding.That is,, at this, by returning to work MA, balladeur train 130 moves to initial position.In addition,, in Figure 10, with thick dotted line, represent movement without the balladeur train 130 of image formation work (after, in same figure too).

Then, master control part 120 is carried out feeding work SA(step S226).As shown in Figure 10 (c), feeding work SA is that the work of predetermined amount of movement is moved in the position while making balladeur train 130 finish from the work of returning MA before without image formation work (black discharge work) to main scanning toward direction.In the present embodiment, the amount of movement of the balladeur train 130 in feeding work SA to main scanning toward direction, is until the end position of image formation work before (in this case the 1st image formation work PA1).That is, feeding work SA is the work that makes balladeur train 130 process on the region AR1 that has formed the 1st printing images PI1.

Then, master control part 120, as shown in Figure 10 (c), carries out the 2nd image formation work PA2(step S230).The 2nd image formation work PA2 is while making balladeur train 130 move the work that from the end position of image formation work (in this case the 1st image formation work PA1) before the region AR2 on printed medium PM forms the 2nd printing images PI2 to main scanning toward direction.In the present embodiment, feeding work SA and the 2nd image formation work PA2 make the work of balladeur train 130 to main scanning toward direction continuous moving, and 2 work is carried out continuously in the mode not stopping across the movement of balladeur train 130 between them.

At this, the width W p2 along main scanning direction that carries out the region AR2 of image formation by the 2nd image formation work PA2 is set at below continuous printing upper distance limit Lth.In addition, the amount of movement that the balladeur train 130 in the above-mentioned work of returning MA returns direction to main scanning is redefined for the total that makes to return required time of work MA and required time of the feeding work SA after this to be become and enough makes the temperature of print head 140 from ceiling temperature Tth, drop to the time of initial temperature Ti.For example, as mentioned above, in the present embodiment, if will return to that amount of movement that balladeur train 130 in work MA returns from direction to main scanning is made as until return with the main scanning that is formed with the region (in this case region AR1) on the printed medium PM of image in image formation work (in this case the 1st image formation work PA1) before the position that the borderline phase of direction side is corresponding, the above-mentioned total ascent time is just enough.Therefore, in the moment that starts the 2nd image formation work PA2, when no matter returning to work MA and starting, the temperature of (, when the 1st image formation work PA1 finishes) how, and the temperature of print head 140 all can drop to initial temperature Ti.Therefore,, although the temperature T of print head 140 rises because of the image formation work (black discharge work) in the 2nd image formation work PA2, can not reach ceiling temperature Tth.In addition, as long as return to the amount of movement that the balladeur train 130 in work MA returns direction to main scanning, meet above-mentioned condition, not necessarily needing to be made as until return with the main scanning that is formed with the region on the printed medium PM of image in image formation work before the position that the borderline phase of direction side is corresponding, can be also less amount of movement.In addition, the width W p2 along main scanning direction of region AR2 can be identical with the width W p1 along main scanning direction of region AR1, also can be different.

Then, the main scanning whether master control part 120 judgement balladeur trains 130 have arrived printed medium PM is toward direction side one end (step S232), in the situation that be judged to be main scanning that balladeur train 130 not yet arrives printed medium PM toward direction side one end (step S232: no), carry out once again and return to work MA(step S222), feeding work SA(step S226) and the 2nd image formation work PA2(step S230) group, carry out once again the judgement of step S232.Like this, master control part 120 is carried out the group of returning to work MA, feeding work SA and the 2nd image formation work PA2 repeatedly, until be judged to be main scanning that balladeur train 130 reached printed medium PM toward direction side one end.The group of the work of returning MA, feeding work SA now and the 2nd image formation work PA2, similarly carries out with the above-mentioned work of returning MA, the feeding work SA of the 1st time and the group of the 2nd image formation work PA2.Even if so repeatedly carry out the group of returning to work MA, feeding work SA and the 2nd image formation work PA2, the temperature T of print head 140 can not reach ceiling temperature Tth yet.

When being judged to be main scanning that balladeur train 130 arrived printed medium PM toward direction side one end (step S232: be), as shown in Figure 10 (c), the image of 1 unit region forms and finishes.In this case, master control part 120 judges the image for the Zone Full of printed medium PM forms whether finish (step S240), form still in unclosed situation (step S240: no) being judged to be image for the Zone Full of printed medium PM, carry out and not carry out China ink and discharge the main scanning that makes balladeur train 130 move to printed medium PM and return the initial position of direction side one end and return to work, with the transportation work (subscan) (step S250) that printed medium PM is carried to sub scanning direction, as shown in Figure 10 (d), using next unit region, (in the example of Figure 10 (d), being the 2nd unit region) is as object, carry out the 1st image formation work PA1(step S210) later processing.Such processing is carried out repeatedly, when being judged to be image for the Zone Full of printed medium PM, forms (step S240: be) while having finished, and cuts apart printing treatment and finishes.

As described above, that at the printing equipment 100 by the 2nd embodiment, carries out cuts apart in printing treatment, first, while carry out making balladeur train 130 to move the 1st image formation work PA1 of region AR1 formation the 1st printing images PI1 on printed medium PM to main scanning toward direction.Then, carry out N time (N is more than 1 integer) while without image form place of working make balladeur train 130 to main scanning return the work of returning MA that direction moves predetermined amount of movement, without image form place of working make the image formation work of balladeur train 130 before moving to main scanning toward direction end position feeding work SA and make balladeur train 130 to main scanning toward direction, move the group of the 2nd image formation work PA2 of region AR2 formation the 2nd printing images PI2 on printed medium PM.For example, as illustrated in Figure 10, in the situation that printed medium width W m is larger and be below 2 times of continuous printing upper distance limit Lth than continuous printing upper distance limit Lth, by carrying out successively 1 order 1 image formation work PA1, returning to work MA, 1 feeding work SA and 1 order 2 image formation work PA2 for 1 time, the image of 1 unit region forms and finishes.In this case, the 1st image formation work PA1 is equivalent to the 1st formation work in technical scheme, the 2nd image formation work PA2 is equivalent to the 2nd formation work in technical scheme, returns to work MA and feeding work SA is equivalent to the adjustment work in technical scheme.At this, from Figure 10 (c), even R, G, B value based on representing each pixel are (0,0,0) printing treatment that the view data ID of the image of preliminary dimension carries out, the region that the brightness of the 1st printing images PI1 is minimum and by N(N=1 in the example of Figure 10) N the 2nd minimum region of printing images PI2 brightness separately that order 2 image formation work PA2 form, be also on main scanning direction, to repeat and do not repeat on sub scanning direction.For example,, in example as shown in figure 10, because the 1st printing images PI1 and the 2nd printing images PI2 do not have overlapped part, so repeat on main scanning direction and do not repeat on sub scanning direction.The printing equipment 100 of the present embodiment, owing to can carrying out the printing treatment of cutting apart as described above, even so be (0 in R, G, the B value as based on representing each pixel, 0,0) temperature of the such print head 140 of printing treatment that the view data ID of image carries out easily rise and printed medium width W m than in the large situation of continuous printing upper distance limit Lth, also can avoid the temperature of print head 140 to reach ceiling temperature Tth, and the image that can realize for printed medium PM integral body form.That is,, regardless of the content of image and/or the size of printed medium PM of printing object, the image that the printing equipment 100 of the present embodiment can both be realized for printed medium PM integral body forms.

In addition, in cutting apart in printing treatment of the 2nd embodiment, although the image of constituent parts region forms by image formation work repeatedly, but because each image formation work is carried out as pre-determined, so it is bad can not make suddenly as the temperature detection result based on thermistor 144 in the past printing work produce the printing of image stopping.

In addition, in cutting apart in printing treatment of the 2nd embodiment, owing to can not carrying out maintaining the work of the mobile halted state of balladeur train 130 as the ST that quits work of the 1st embodiment on printed medium PM, so can prevent the situation that user thinks plant failure by mistake.

In addition, in cutting apart in printing treatment of the 2nd embodiment, owing to returning to amount of movement that balladeur train 130 in work MA returns from direction to main scanning, be until return with the main scanning that is formed with the region on the printed medium PM of image in image formation work before the position that the borderline phase of direction side is corresponding, so it is stable to make to start the translational speed of balladeur train 130 in the moment of the 2nd image formation work PA2 after returning to work MA and feeding work SA, can suppress between the 1st printing images PI1 and the 2nd printing images PI2, or the decline of the obvious such image quality in border between 2 the 2nd printing images PI2.

In addition, printing equipment 100, performed the 1st image formation work PA1 and the number of times of the 2nd image formation work PA2 and position (the region AR1 on printed medium PM while cutting apart printing treatment by decision, AR2), based on them, come divided image data ID(or printed data), data after utilization is cut apart, can carry out the printing treatment of cutting apart as described above.

C. the 3rd embodiment:

Figure 11 means the flow chart of the flow process of cutting apart printing treatment of the 3rd embodiment.In addition, Figure 12 means the key diagram of the summary of cutting apart printing treatment of the 3rd embodiment.Figure 12 and Fig. 8 are same, show and represent that R, the G of each pixel, B value are (0 having inputted from main frame 200,0,0) the view data ID(of the image of preliminary dimension, the view data corresponding with monochromatic picture black) situation under the summary of cutting apart printing treatment carried out by printing equipment 100 based on this view data ID.The 3rd embodiment cut apart printing treatment and the 1st embodiment is same, be the printing treatment (with step S140) that (the step S120 of Fig. 6: no) carries out in the situation that printed medium width W m is larger than continuous printing upper distance limit Lth.

First, master control part 120(Fig. 2 of printing equipment 100), as shown in Figure 12 (a), carry out the 1st image formation work PA1(step S210).The 1st image formation work PA1 is while making balladeur train 130 move the work of region AR1 formation the 1st printing images PI1 on printed medium PM to main scanning toward direction.The width W p1 along main scanning direction that forms the region AR1 of the 1st printing images PI1 by the 1st image formation work PA1 is set to below continuous printing upper distance limit Lth.Therefore,, although the temperature T of print head 140 is because the 1st image formation work PA1 rises, can not reach ceiling temperature Tth.

Then, master control part 120 is carried out the 1st feeding work SA1(step S214).As shown in Figure 12 (a), the 1st feeding work SA1 forms place of working without image to make balladeur train 130 to main scanning toward direction, move the work of predetermined amount of movement.The 1st feeding work SA1 and image formation work before (in this case the 1st image formation work PA1) are carried out continuously in the mode not stopping across the movement of balladeur train 130 between them.The amount of movement of the balladeur train 130 in the 1st feeding work SA1 is redefined for, and the 1st required time of feeding work SA1 was become and enough make the temperature of print head 140 from ceiling temperature Tth, drop to such amount of movement of time of initial temperature Ti.Therefore, when the 1st feeding work SA1 finishes, when no matter the 1st feeding work SA1 starts, the temperature of (, when the 1st image formation work PA1 finishes) how, and the temperature of print head 140 all can drop to initial temperature Ti.

Then, the main scanning whether master control part 120 judgement balladeur trains 130 have arrived printed medium PM is toward direction side one end (step S216), in the situation that be judged to be main scanning that balladeur train 130 not yet arrives printed medium PM toward direction side one end (step S216: no), carry out once again the 1st image formation work PA1(step S210) and the 1st feeding work SA1(step S214) group, carry out once again the judgement of step S216.Like this, master control part 120 is while making balladeur train 130 repeatedly carry out the group of the 1st image formation work PA1 and the 1st feeding work SA1 to main scanning toward direction continuous moving, until be judged to be main scanning that balladeur train 130 arrived printed medium PM toward before direction side one end.Even if so repeatedly carry out the group of the 1st image formation work PA1 and the 1st feeding work SA1, the temperature T of print head 140 can not reach ceiling temperature Tth yet.

When being judged to be main scanning that balladeur train 130 arrived printed medium PM toward direction side one end (step S216: be), master control part 120 is carried out the 2nd image formation work PA2(step S230).As shown in Figure 12 (b), while the 2nd image formation work PA2 makes the balladeur train 130 with print head 140 return to main scanning the work that the region AR2 of direction mobile width Wp2 on printed medium PM forms the 2nd printing images PI2.At this, the width W p2 along main scanning direction of region AR2 is set to below continuous printing upper distance limit Lth.Therefore,, although the temperature T of print head 140 is because the 2nd image formation work PA2 rises, can not reach ceiling temperature Tth.In addition, carry out in identical region, the region with carry out 1st feeding work SA1 of the 2nd image formation work PA2 on printed medium PM.Therefore, the amount of movement (width W p2) of the balladeur train 130 in the 2nd image formation work PA2 is identical with the amount of movement of balladeur train 130 in the 1st feeding work SA1.Therefore, width W p2 is set to the 1st condition taken into account below continuous printing upper distance limit Lth and required time of balladeur train 130 mobile width Wp2 for enough making the temperature of print head 140 drop to the 2nd condition of the time of initial temperature Ti from ceiling temperature Tth.

Then, master control part 120 is carried out the 2nd feeding work SA2(step S234).As shown in Figure 12 (b), the 2nd feeding work SA2 forms place of working without image to make balladeur train 130 return to main scanning the work that direction moves predetermined amount of movement.The 2nd feeding work SA2 and image formation work before (in this case the 2nd image formation work PA2) are carried out continuously in the mode not stopping across the movement of balladeur train 130 between them.In addition, carry out in identical region, the region with carry out 1st image formation work PA1 of the 2nd feeding work SA2 on printed medium PM.Therefore, the amount of movement (width W p1) of the balladeur train 130 in the 1st image formation work PA1 is identical with the amount of movement of balladeur train 130 in the 2nd feeding work SA2.Therefore, width W p1 is set to the 1st condition taken into account below continuous printing upper distance limit Lth and required time of balladeur train 130 mobile width Wp1 for enough making the temperature of print head 140 drop to the 2nd condition of the time of initial temperature Ti from ceiling temperature Tth.

Then, direction side one end (step S236) is returned in the main scanning whether master control part 120 judgement balladeur trains 130 have arrived printed medium PM, in the situation that be judged to be the main scanning that balladeur train 130 not yet reaches printed medium PM, return direction side one end (step S236: no), carry out once again the 2nd image formation work PA2(step S230) and the 2nd feeding work SA2(step S234) group, carry out once again the judgement of step S236.Like this, while master control part 120 makes balladeur train 130 return to main scanning the group that direction continuous moving is carried out the 2nd image formation work PA2 and the 2nd feeding work SA2 repeatedly, until be judged to be the main scanning of balladeur train 130 arrival printed medium PM, return direction side one end.Even if so repeatedly carry out the group of the 2nd image formation work PA2 and the 2nd feeding work SA2, the temperature T of print head 140 can not reach ceiling temperature Tth yet.

When direction side one end is returned in the main scanning that is judged to be balladeur train 130 and has arrived printed medium PM (step S236: be), as shown in Figure 12 (b), the image of 1 unit region forms and finishes.In this case, master control part 120 judges the image for the Zone Full of printed medium PM forms whether finish (step S240), form still in unclosed situation (step S240: no) being judged to be image for the Zone Full of printed medium PM, execution is carried transportation work (subscan) (step S250) from printed medium PM to sub scanning direction, as shown in Figure 12 (c), using next unit region, (in the example of Figure 12 (c), being the 2nd unit region) is as object, carry out the 1st image formation work PA1(step S210) later processing.Such processing is carried out repeatedly, when being judged to be image for the Zone Full of printed medium PM, forms (step S240: be) while having finished, and cuts apart printing treatment and finishes.

As described above, that at the printing equipment 100 by the 3rd embodiment, carries out cuts apart in printing treatment, first, carry out N time (N is more than 1 integer) while the region AR1 that balladeur train 130 is moved to main scanning toward direction on printed medium PM forms the 1st image formation work PA1 of the 1st printing images PI1 and makes balladeur train 130 move the group of the 1st feeding work SA1 of predetermined amount of movement to main scanning toward direction without image formation place of working.Then, carry out on one side and make for N time balladeur train 130 return direction to main scanning to move the 2nd image formation work PA2 of region AR2 formation the 2nd printing images PI2 on printed medium PM and make balladeur train 130 return to main scanning the group that direction moves the 2nd feeding work SA2 of predetermined amount of movement without image formation place of working.The 1st feeding work SA1 is the work of moving balladeur train 130 to the direction contrary with the 2nd image formation work PA2 in the execution area of the 2nd image formation work PA2, and the 2nd feeding work SA2 is the work of moving balladeur train 130 to the direction contrary with the 1st image formation work PA1 in the execution area of the 1st image formation work PA1.For example, as illustrated in Figure 12, in the situation that printed medium width W m is larger and be below 2 times of continuous printing upper distance limit Lth than continuous printing upper distance limit Lth, by carrying out successively 1 order 1 image formation work PA1,1 order 1 feeding work SA1,1 order 2 image formation work PA2,1 order 2 feeding work SA2, the image of 1 unit region forms and finishes.In this case, the 1st image formation work PA1 is equivalent to the 1st formation work in technical scheme, and the 2nd image formation work PA2 is equivalent to the 2nd formation work in technical scheme, and the 1st feeding work SA1 is equivalent to the adjustment work in technical scheme.At this, from Figure 12 (b), even R, G, B value based on representing each pixel are (0,0,0) printing treatment that the view data ID of the image of preliminary dimension carries out, by N(N=1 in the example of Figure 12) the minimum region and N the region that the 2nd printing images PI2 brightness is separately minimum forming by N order 2 image formation work PA2 of N the 1st printing images PI1 brightness separately that order 1 image formation work PA1 forms is also on main scanning direction, to repeat and do not repeat on sub scanning direction.For example,, in the example shown in Figure 12, because the 1st printing images PI1 and the 2nd printing images PI2 do not have overlapped part, so repeat on main scanning direction and do not repeat on sub scanning direction.The printing equipment 100 of the present embodiment, owing to can carrying out the printing treatment of cutting apart as described above, even so be (0 in R, G, the B value as based on representing each pixel, 0,0) temperature of the such print head 140 of printing treatment that the view data ID of image carries out easily rise and printed medium width W m than in the large situation of continuous printing upper distance limit Lth, also can avoid the temperature of print head 140 to reach ceiling temperature Tth, and the image that can realize for printed medium PM integral body form.That is,, regardless of the content of image and/or the size of printed medium PM of printing object, the image that the printing equipment 100 of the present embodiment can both be realized for printed medium PM integral body forms.

In addition, in cutting apart in printing treatment of the 3rd embodiment, although the image of constituent parts region forms by image formation work repeatedly, but because each image formation work is carried out as predetermined, so it is bad can not make suddenly as the temperature detection result based on thermistor 144 in the past printing work produce the printing of image stopping.

In addition, in cutting apart in printing treatment of the 3rd embodiment, owing to not carrying out maintaining the work of the mobile halted state of balladeur train 130 as the ST that quits work of the 1st embodiment on printed medium PM, so can prevent the situation that user thinks plant failure by mistake.In addition, in cutting apart in printing treatment of the 3rd embodiment, because utilizing balladeur train 130, the such place of working of the work of returning MA of quit work ST and the 2nd embodiment without the 1st embodiment forms along the continuous mobile image that just finishes unit region that comes and goes for 1 time of main scanning direction, so can suppress the printing treatment increase of required time.

In addition, in cutting apart in printing treatment of the 3rd embodiment, because the 1st image formation work PA1 and the 2nd image formation work PA2 are while balladeur train 130 continuous movings are carried out, so the translational speed of the balladeur train 130 in the time of can making to form the boundary member of each image is stable, can suppress the obvious such image quality reduction in border between the 1st printing images PI1 and the 2nd printing images PI2.

In addition, printing equipment 100, performed the 1st image formation work PA1 and the number of times of the 2nd image formation work PA2 and position (the region AR1 on printed medium PM while cutting apart printing treatment by decision, AR2), based on them, come divided image data ID(or printed data), according to image, form job order and read and utilize the data after cutting apart, thereby can carry out the printing treatment of cutting apart as described above.

In addition, in cutting apart in printing treatment of the 3rd embodiment, the 1st printing images PI1 follows the movement of balladeur train 130 to main scanning toward direction and the image that forms, the 2nd printing images PI2 follows balladeur train 130 to return the movement of direction and the image that forms to main scanning, therefore has the obvious situation of boundary member of the 1st printing images PI1 and the 2nd printing images PI2.Therefore,, in cutting apart in printing treatment of the 3rd embodiment, also can adopt for making the inconspicuous known image quality adjustment technology of boundary member of the 1st printing images PI1 and the 2nd printing images PI2.

Figure 13 means the key diagram of the summary of cutting apart printing treatment of the variation of the 3rd embodiment.Variation shown in Figure 13 cut apart printing treatment be the 3rd embodiment shown in Figure 12 cut apart printing treatment in variation that the relation reversion of the relation of the 1st image formation work PA1 and the 1st feeding work SA1 and the 2nd image formation work PA2 and the 2nd feeding work SA2 is obtained.; in the variation shown in Figure 13; as shown in Figure 13 (a); master control part 120 is while making balladeur train 130 repeatedly carry out the group of the 1st feeding work SA1 and the 1st image formation work PA1 to main scanning toward direction continuous moving, until be judged to be main scanning that balladeur train 130 arrived printed medium PM toward direction side one end.Then, master control part 120 is while making balladeur train 130 return to main scanning the group that direction continuous moving is carried out the 2nd feeding work SA2 and the 2nd image formation work PA2 repeatedly, until be judged to be before main scanning that balladeur train 130 arrived printed medium PM returns direction side one end.For example, as illustrated in Figure 13, in the situation that printed medium width W m is larger and be below 2 times of continuous printing upper distance limit Lth than continuous printing upper distance limit Lth, by carrying out successively 1 order 1 feeding work SA1,1 order 1 image formation work PA1,1 order 2 feeding work SA2,1 order 2 image formation work PA2, the image of 1 unit region forms and finishes.In this case, the 1st image formation work PA1 is equivalent to the 1st formation work in technical scheme, and the 2nd image formation work PA2 is equivalent to the 2nd formation work in technical scheme, and the 2nd feeding work SA2 is equivalent to the adjustment work in technical scheme.Like this, in cutting apart in printing treatment of the variation shown in Figure 13, even be (0 in R, G, the B value as based on representing each pixel, 0,0) temperature of the such print head 140 of printing treatment that the view data ID of image carries out easily rise and printed medium width W m than in the large situation of continuous printing upper distance limit Lth, also can avoid the temperature of print head 140 to reach ceiling temperature Tth, and the image that can realize for printed medium PM integral body form.

D. the 4th embodiment:

Figure 14 means the flow chart of the flow process of cutting apart printing treatment of the 4th embodiment.In addition, Figure 15 means the key diagram of the summary of cutting apart printing treatment of the 4th embodiment.Figure 15 and Fig. 8 are same, show and represent that R, the G of each pixel, B value are (0 having inputted from main frame 200,0,0) the view data ID(of the image of preliminary dimension, the view data corresponding with monochromatic picture black) situation under the summary of cutting apart printing treatment carried out by printing equipment 100 based on this view data ID.The 4th embodiment cut apart printing treatment and the 1st embodiment is same, be the printing treatment (with step S140) that (the step S120 of Fig. 6: no) carries out in the situation that printed medium width W m is larger than continuous printing upper distance limit Lth.

First, master control part 120(Fig. 2 of printing equipment 100), as shown in Figure 15 (a) shows, carry out the 1st image formation work PA1(step S210), then carry out the 1st feeding work SA1(step S214), and then then carry out the 2nd image formation work PA2(step S224).The 1st image formation work PA1 is while making to have the balladeur train 130 of print head 140 to the work of the main scanning formation of the region AR1 on printed medium PM the 1st printing images PI1 toward direction mobile width Wp1, while the 2nd image formation work PA2 makes balladeur train 130 to the work of the main scanning formation of the region AR2 on printed medium PM the 2nd printing images PI2 toward direction mobile width Wp2.In addition, the 1st feeding work SA1 forms place of working without image to make balladeur train 130 to main scanning toward direction, move the work of predetermined amount of movement.The 1st image formation work PA1, the 1st feeding work SA1 and the 2nd image formation work PA2 carry out continuously in the mode not stopping across the movement of balladeur train 130 between them.When the 2nd image formation work PA2 finishes, the main scanning that balladeur train 130 arrives printed medium PM is toward direction side one end.

Then, master control part 120, as shown in Figure 15 (b), carries out the 2nd feeding work SA2(step S228), then carry out the 3rd image formation work PA3(step S231), and then then carry out the 3rd feeding work SA3(step S233).The 2nd feeding work SA2 and the 3rd feeding work SA3 form place of working without image to make balladeur train 130 return to main scanning the work that direction moves predetermined amount of movement.In addition, while the 3rd image formation work PA3 makes balladeur train 130 return to main scanning the work that the region AR3 of direction mobile width Wp3 on printed medium PM forms the 3rd printing images PI3.The 2nd feeding work SA2, the 3rd image formation work PA3 and the 3rd feeding work SA3 carry out continuously in the mode not stopping across the movement of balladeur train 130 between them.When the 3rd feeding work SA3 finishes, direction side one end (that is, initial position) is returned in the main scanning that balladeur train 130 arrives printed medium PM.

At this, as shown in Figure 15 (a) and Figure 15 (b), carry out region on the printed medium PM of the 2nd feeding work SA2 identical with the region (region AR2) of carrying out on the printed medium PM of the 2nd image formation work PA2, carry out region (region AR3) on the printed medium PM of the 3rd image formation work PA3 identical with the region of carrying out on the printed medium PM of the 1st feeding work SA1, the region (region AR1) of carrying out on the printed medium PM of region on the printed medium PM of the 3rd feeding work SA3 and execution the 1st image formation work PA1 is identical.

Carrying out the width W p1 along main scanning direction of the region AR1 of the 1st image formation work PA1, the width W p2 of region AR2 that carries out the 2nd image formation work PA2 and the width W p3 that carries out the region AR3 of the 3rd image formation work PA3 is all set to below continuous printing upper distance limit Lth.In addition, the amount of movement of the balladeur train 130 in the 1st feeding work SA1 is redefined for, and is become enough make the temperature of the print head 140 supposed when the 1st image formation work PA1 finishes to drop to such amount of movement of time of initial temperature Ti the 1st required time of feeding work SA1.In addition, the amount of movement of the balladeur train 130 in the 2nd feeding work SA2 is redefined for, and is become enough make the temperature of the print head 140 supposed when the end of the 2nd image formation work PA2 to drop to such amount of movement of time of initial temperature Ti the 2nd required time of feeding work SA2.Therefore, although the temperature T of print head 140 rises but can not reach ceiling temperature Tth because of the 1st image formation work PA1, and during ensuing the 1st feeding work SA1, drop to initial temperature Ti, although because ensuing the 2nd image formation work PA2 rises but can not reach ceiling temperature Tth, and during ensuing the 2nd feeding work SA2, drop to initial temperature Ti, although because ensuing the 3rd image formation work PA3 rises but can not reach ceiling temperature Tth, and drop to initial temperature Ti during ensuing the 3rd feeding work SA3.In addition, in the present embodiment, width W p1 and width W p2 are approximately 1/4th of printed medium width W m, and width W p3 is approximately 1/2nd of printed medium width W m.So, met above-mentioned condition.

When the 3rd feeding work SA3 finishes, as shown in Figure 15 (b), the image of 1 unit region forms and finishes.Master control part 120 judges the image for the Zone Full of printed medium PM forms whether finish (step S240), form still in unclosed situation (step S240: no) being judged to be image for the Zone Full of printed medium PM, execution is carried transportation work (subscan) (step S250) from printed medium PM to sub scanning direction, as shown in Figure 15 (c), using next unit region, (in the example of Figure 15 (c), being the 2nd unit region), as object, carries out the 1st image formation work PA1(step S210) later processing.Such processing is carried out repeatedly, when being judged to be the image finishing for the Zone Full of printed medium PM and forming (step S240: be), cuts apart printing treatment and finishes.

As described above, that at the printing equipment 100 by the 4th embodiment, carries out cuts apart in printing treatment, first, carry out while making balladeur train 130 move the 1st image formation work PA1 of region AR1 formation the 1st printing images PI1 on printed medium PM to main scanning toward direction, after the 1st image formation work PA1, without image, forming place of working makes balladeur train 130 to main scanning toward direction, move the 1st feeding work SA1 of predetermined amount of movement, with after the 1st feeding work SA1 while making balladeur train 130 move the group that region AR2 on printed medium PM forms the 2nd image formation work PA2 of the 2nd printing images PI2 to main scanning toward direction.Then, carry out on one side and without image, form place of working and make balladeur train 130 return direction to main scanning to move the 2nd feeding work SA2 of predetermined amount of movement, continue the 2nd feeding work SA2 after, make balladeur train 130 to main scanning, return direction to move the 3rd image formation work PA3 of region AR3 formation the 3rd printing images PI3 on printed medium PM and without image formation place of working, make balladeur train 130 return to main scanning the group that direction moves the 3rd feeding work SA3 of predetermined amount of movement after the 3rd image formation work PA3.In addition, the 1st image formation work PA1 is equivalent to the 1st formation work in technical scheme, the 2nd image formation work PA2 is equivalent to the 2nd formation work in technical scheme, the 3rd image formation work PA3 is equivalent to the 3rd formation work in technical scheme, the 1st feeding work SA1 is equivalent to the 1st adjustment work in technical scheme, the 2nd feeding work SA2 is equivalent to the 2nd adjustment work in technical scheme, and the 3rd feeding work SA3 is equivalent to the 3rd adjustment work in technical scheme.At this, the region of carrying out on the printed medium PM of the 2nd feeding work SA2 is identical with the region of carrying out the 2nd image formation work PA2, the region of carrying out the 3rd image formation work PA3 is identical with the region of carrying out the 1st feeding work SA1, and the region of carrying out the 3rd feeding work SA3 is identical with the region of carrying out the 1st image formation work PA1.From Figure 15 (b), even R, G, B value based on representing each pixel are (0,0,0) printing treatment that the view data ID of the image of preliminary dimension carries out, the 1st printing images PI1, the 2nd printing images PI2 and the 3rd minimum region of printing images PI3 brightness are separately also on main scanning direction, to repeat and do not repeat on sub scanning direction.For example,, in the example shown in Figure 15, because the 1st printing images PI1, the 2nd printing images PI2 and the 3rd printing images PI3 do not have overlapped part, so repeat on main scanning direction and do not repeat on sub scanning direction.The printing equipment 100 of the present embodiment, owing to can carrying out the printing treatment of cutting apart as described above, even so be (0 in R, G, the B value as based on representing each pixel, 0,0) temperature of the such print head 140 of printing treatment that the view data ID of image carries out easily rise and printed medium width W m than in the large situation of continuous printing upper distance limit Lth, also can avoid the temperature of print head 140 to reach ceiling temperature Tth, and the image of realizing for printed medium PM integral body form.That is,, regardless of the content of image and/or the size of printed medium PM of printing object, the image that the printing equipment 100 of the present embodiment can both be realized for printed medium PM integral body forms.

In addition, in cutting apart in printing treatment of the 4th embodiment, although the image of constituent parts region forms by image formation work repeatedly, but because each image formation work is carried out as predetermined, so it is bad can not make suddenly as the temperature detection result based on thermistor 144 in the past printing work that the printing of image occurs stopping.

In addition, in cutting apart in printing treatment of the 4th embodiment, owing to not maintaining the work of the mobile halted state of balladeur train 130 as the ST that quits work of the 1st embodiment on printed medium PM, so can prevent the situation that user thinks plant failure by mistake.In addition, in cutting apart in printing treatment of the 4th embodiment, owing to there is no the such work of the work of returning MA of quit work ST and the 2nd embodiment of the 1st embodiment, and utilize balladeur train 130 to form along the continuous mobile image that just finishes unit region that comes and goes for 1 time of main scanning direction, so can suppress the printing treatment increase of required time.

In addition, in cutting apart in printing treatment of the 4th embodiment, because the 1st image formation work PA1, the 2nd image formation work PA2 and the 3rd image formation work PA3 are while balladeur train 130 continuous movings are carried out, so the translational speed of the balladeur train 130 in the time of can making to form the boundary member of each image is stable, can suppress the obvious such image quality reduction in border between each image.And then, in cutting apart in printing treatment of the 4th embodiment, owing to each width W p can being set as make the boundary member of each image to be configured in the position away from printed medium PM central authorities, so can make the border between each image so unobvious.

In addition, printing equipment 100 is by divided image data ID(or printed data), according to image, form job order and read and utilize the data after cutting apart, can carry out the printing treatment of cutting apart as described above.

In addition, in cutting apart in printing treatment of the 4th embodiment, the 1st printing images PI1 and the 2nd printing images PI2 are the movement to main scanning toward direction and the image that forms with balladeur train 130, the 3rd printing images PI3 returns the movement of direction and the image that forms with balladeur train 130 to main scanning, so there is the obvious situation of boundary member between each image.Therefore,, in cutting apart in printing treatment of the 4th embodiment, also can adopt for making the inconspicuous known image quality adjustment technology of boundary member between each image.

In addition,, in the 4th embodiment, in the situation that printed medium width W m is the more than 2 times of continuous printing upper distance limit Lth, also can be used as mistake and do not carry out printing treatment.

In addition, in cutting apart in printing treatment of the 4th embodiment shown in Figure 15, also can make the relation reversion of image formation work and feeding work., can be made as: while balladeur train 130 is moved to main scanning toward direction, replace the 1st image formation work PA1 in Figure 15 (a) and carry out the 1st feeding work SA1, then replace the 1st feeding work SA1 and carry out the 1st image formation work PA1, and then then replace the 2nd image formation work PA2 and carry out the 2nd feeding work SA2, then while making balladeur train 130 return direction to main scanning, move and replace the 2nd feeding work SA2 of Figure 15 (b) and carry out the 2nd image formation work PA2, then replace the 3rd image formation work PA3 and carry out the 3rd feeding work SA3, and then then replace the 3rd feeding work SA3 and carry out the 3rd image formation work PA3.In this case, the 1st image formation work PA1 is equivalent to the 1st formation work in technical scheme, the 2nd image formation work PA2 is equivalent to the 2nd formation work in technical scheme, the 3rd image formation work PA3 is equivalent to the 3rd formation work in technical scheme, the 1st feeding work SA1 is equivalent to the 1st adjustment work in technical scheme, the 2nd feeding work SA2 is equivalent to the 2nd adjustment work in technical scheme, and the 3rd feeding work SA3 is equivalent to the 3rd adjustment work in technical scheme.So, also can avoid the temperature of print head 140 to reach ceiling temperature Tth, and the image of realizing for printed medium PM integral body form.

E. the 5th embodiment:

Figure 16 means the flow chart of flow process of the printing treatment of the 5th embodiment.In addition, Figure 17 means the key diagram of summary of the printing treatment of the 5th embodiment.In Figure 17, illustrated and represented that R, the G of each pixel, B value are (0 having inputted from main frame 200,0,0) the view data ID(of the image of preliminary dimension, the view data corresponding with monochromatic picture black) situation under the summary of the printing treatment carried out by printing equipment 100 based on this view data ID.In addition, in the 5th embodiment, different from the 1st above-mentioned embodiment to the 4 embodiment, no matter the magnitude relationship of printed medium width W m and continuous printing upper distance limit Lth how, is all carried out printing treatment according to the flow chart shown in Figure 16.

First, master control part 120(Fig. 2 of printing equipment 100), as shown in Figure 17 (a) shows, start the 1st image formation work PA1(step S310).The 1st image formation work PA1 is while making the balladeur train 130 with print head 140 form the work of the 1st printing images PI1 to main scanning toward direction continuous moving on printed medium PM.Whether the temperature T that in addition, master control part 120 monitors the print head 140 being detected from the thermistor 144 of print head 140 (step S320) monitor that main scanning that whether balladeur train 130 arrive printed medium PM is toward direction side one end (step S330) more than the ceiling temperature Tth of normal operation that can guarantee above-mentioned print head 140.

When the temperature T of print head 140 reaches ceiling temperature Tth when above (step S320: be), because the discharge limiting unit 152 of print head 140 is carried out the restriction of black discharge work, so discharging, China ink is interrupted.That is, balladeur train 130 can not be proceeded image formation work.Therefore, after this, the work of balladeur train 130 becomes without image and forms the 1st feeding work SA1(that moves toward direction to main scanning in place of working with reference to Figure 17 (a)).Now, the position (the 1st position) of master control part 120 storage balladeur trains 130 start image to form the data used to the preservation (step S340) of predetermined storage area.In addition, as mentioned above, the position of balladeur train 130 can based on from following the rotation of carriage motor 132, export pulse type signal encoder output output signal and determine.

Whether the temperature T that then, master control part 120 monitors print heads 140 (step S350) monitor that main scanning that whether balladeur train 130 arrived printed medium PM is toward direction side one end (step S360) below the recovery temperature Tr of above-mentioned print head 140.When temperature T reaches recovery temperature Tr when following (step S350: be), the restrictions because the discharge limiting unit 152 of print head 140 is removed China ink discharge work, re-start so China ink is discharged.That is, balladeur train 130 can re-start image formation work.Therefore, after this, the work of balladeur train 130 becomes the 1st image formation work PA1(with reference to Figure 17 (a)).Now, the position (the 2nd position) of master control part 120 storage balladeur trains 130 finish image just and form the data used to the preservation (step S370) of predetermined storage area.

Master control part 120 is carried out processing as above repeatedly.That is, repeatedly carry out the 1st image formation work PA1 and the 1st feeding work SA1.In R, G, B value based on representing each pixel, be (0,0,0) in the situation of the printing treatment that the view data ID of image carries out, be formed with the width W p1 of the region AR1 of the 1st printing images PI1 by each the 1st image formation work PA1, Lth is identical in fact with continuous printing upper distance limit.

Be judged to be in the situation that the main scanning that in the execution of the 1st image formation work PA1, balladeur train 130 has arrived printed medium PM toward direction side one end (step S330: be), master control part 120 judges that in above-mentioned storage area, whether preserving image forms the data (step S380) of using.In the situation that preserve image, form the data (step S380: be) of using, the image that reads the 1st position of stored balladeur train 130 and the 2nd position and preserve forms the data (step S390) of using, and carries out the 2nd image formation work PA2(step S400).As shown in Figure 17 (b), while the 2nd image formation work PA2 makes balladeur train 130 return direction toward direction side one end to main scanning from the main scanning of printed medium PM to move to main scanning and return the work that the region (region AR2) of the execution 1st feeding work SA1 of direction side one end on printed medium PM forms the 2nd printing images PI2.In addition, also can be described as the time execution feeding work that carries out image forms in the 2nd image formation work PA2.Now, the 1st position of the balladeur train 130 of master control part 120 based on read and the 2nd position, determined execution on printed medium PM the region of the 1st feeding work SA1 (that is, should form the region AR2 of the 2nd printing images PI2).In addition, the data that represent the 2nd printing images PI2 are the data that read from storage area.Therefore, master control part 120 can form the data of using with the 1st position and the 2nd position and image and carry out the 2nd image formation work PA2.Due to the end of the 2nd image formation work PA2, as shown in Figure 17 (b), the image of 1 unit region forms and finishes.

On the other hand, not yet preserving image and forming the situation (step S380: no) of the data use, be once all do not carry out the 1st feeding work SA1 and main scanning that balladeur train 130 arrives printed medium PM toward the situation of direction side one end, only just finish by 1 order 1 image formation work PA1 the situation that the image of 1 unit region forms.In R, G, B value based on representing each pixel, be (0,0,0) in the printing treatment that the view data ID of image carries out, at printed medium width W m, be continuous printing upper distance limit Lth following in the situation that, only by 1 order 1 image formation work PA1, with regard to finishing the image of 1 unit region, form.In this case, because master control part 120 is without carrying out the 2nd image formation work PA2, so do not carry out China ink, does not discharge to carry out and make balladeur train 130 return to main scanning the initial position that direction moves to return to work, carry out step S410 described later and judge.

In addition, in the situation that the main scanning that in being judged to be the execution of the 1st feeding work SA1, balladeur train 130 has arrived printed medium PM is toward direction side one end (step S360: be), owing to must preserve image in storage area, form the data of using, so master control part 120 is with above-mentioned same, read the data (step S390) that the 1st position of stored balladeur train 130 and the image formation of the 2nd position and preservation are used, carry out the 2nd image formation work PA2(step S400).Thus, the image of 1 unit region forms and finishes.

When the image of 1 unit region forms end, master control part 120 judges the image for the Zone Full of printed medium PM forms whether finish (step S410), form still in unclosed situation (step S410: no) being judged to be image for the Zone Full of printed medium PM, execution is carried transportation work (subscan) (step S420) from printed medium PM to sub scanning direction, as shown in Figure 17 (c), using next unit region, (in the example of Figure 17 (c), being the 2nd unit region) is as object, carry out the 1st image formation work PA1(step S310) later processing.Such processing is carried out repeatedly, when being judged to be image for the Zone Full of printed medium PM, forms (step S410: be) while having finished, and printing treatment finishes.

As described above, in the printing treatment of carrying out at the printing equipment 100 by the 5th embodiment, first, repeatedly carry out while the region AR1 that balladeur train 130 is moved to main scanning toward direction on printed medium PM and form the 1st image formation work PA1 of the 1st printing images PI1 and form without image the 1st feeding work SA1 that place of working makes balladeur train 130 move toward direction to main scanning, until balladeur train moves to the main scanning of printed medium PM toward direction side one end.Then, carry out on one side and make balladeur train 130 toward direction side one end to main scanning, return direction from the main scanning of printed medium PM to move to main scanning the 2nd image formation work PA2 of region formation the 2nd printing images PI2 of the 1st feeding work SA1 that returned the execution of direction side one end on printed medium PM.For example, in the example of Figure 17, by carrying out successively the first half, 1 of the 1st image formation work PA1, later half, the 1 order 2 image formation work PA2(feeding work+image formation work+feedings of 1 feeding work SA1, the 1st image formation work PA1 are worked one after another), the image of 1 unit region forms and finishes.In this case, the first half of the 1st image formation work PA1 is equivalent to the 1st formation work in technical scheme, the later half of the 1st image formation work PA1 is equivalent to the 2nd formation work in technical scheme, in the 2nd image formation work PA2, the actual work of carrying out image formation is equivalent to the 3rd formation work in technical scheme, the 1st feeding work SA1 is equivalent to the 1st adjustment work in technical scheme, feeding work in the 2nd image formation work PA2 before the actual work of carrying out image formation is equivalent to the 2nd adjustment work in technical scheme, feeding work in the 2nd image formation work PA2 after the actual work of carrying out image formation is equivalent to the 3rd adjustment work in technical scheme.At this, from Figure 17 (b) also, even R, G, B value based on representing each pixel are (0,0,0) printing treatment that the view data ID of the image of preliminary dimension carries out, the 1st printing images PI1 forming by the 1st image formation work PA1 and the 2nd minimum region of printing images PI2 brightness separately forming by the 2nd image formation work PA2 are also on main scanning direction, to repeat and do not repeat on sub scanning direction.For example,, in the example shown in Figure 17, because the 1st printing images PI1 and the 2nd printing images PI2 do not have overlapped part, so repeat on main scanning direction and do not repeat on sub scanning direction.The printing equipment 100 of the present embodiment, owing to can carrying out printing treatment as described above, even so be (0 in R, G, the B value as based on representing each pixel, 0,0) temperature of the such print head 140 of printing treatment that the view data ID of image carries out easily rise and printed medium width W m than in the large situation of continuous printing upper distance limit Lth, also can realize for the image of printed medium PM integral body and forming.That is,, regardless of the content of image and the size of printed medium PM of printing object, the image that the printing equipment 100 of the present embodiment can both be realized for printed medium PM integral body forms.

In addition, in the printing treatment of the 5th embodiment, owing to carrying out maintaining the work of the mobile halted state of balladeur train 130 unlike the ST that quits work of the 1st embodiment on printed medium PM, so can prevent the situation that user thinks plant failure by mistake.In addition, in the printing treatment of the 5th embodiment, owing to there is no the such work of the work of returning MA of quit work ST and the 2nd embodiment of the 1st embodiment, and utilize balladeur train 130 to form along the continuous mobile image that just finishes unit region that comes and goes for 1 time of main scanning direction, so can suppress the printing treatment increase of required time.

In addition, in the printing treatment of the 5th embodiment, because the 1st image formation work PA1 and the 2nd image formation work PA2 are while balladeur train 130 continuous movings are carried out, so the translational speed of the balladeur train 130 in the time of can making to form the boundary member of each image is stable, can suppress the obvious such image quality reduction in border between the 1st printing images PI1 and the 2nd printing images PI2.

In addition, in the above description, master control part 120, when the temperature T of print head 140 reaches ceiling temperature Tth when above, start image to form the data use to the preservation (step S340) of predetermined storage area, when temperature T becomes recovery temperature Tr when following, finish the preservation (step S370) that image forms the data of using, but the timing that the preservation that also image can be formed to the data use starts is made as the temperature T of print head 140 reaches the 2nd more than ceiling temperature timing than the low predetermined enough and to spare temperature of ceiling temperature Tth, also image can be formed to temperature T that timing that the preservation of the data use finishes is made as print head 140 and become the 2nd timing below recovery temperature than the high predetermined enough and to spare temperature of recovery temperature Tr.So required data in the time of, can preserving effectively the 2nd image formation work PA2.

In addition, in the printing treatment of the 5th embodiment, the 1st printing images PI1 is the movement to main scanning toward direction and the image that forms with balladeur train 130, the 2nd printing images PI2 returns the movement of direction and the image that forms with balladeur train 130 to main scanning, therefore has the obvious situation of boundary member of the 1st printing images PI1 and the 2nd printing images PI2.Therefore,, in the printing treatment of the 5th embodiment, also can adopt for making the inconspicuous known image quality adjustment technology of boundary member of the 1st printing images PI1 and the 2nd printing images PI2.
