Patent document 1: Japanese Unexamined Patent Publication 2008-213152 publication
But there are the following problems for image processing system in the past: in order to form the image of multiple texture, the kind of ink suitably must be changed according to desired texture.
Summary of the invention
Therefore, the object of the present invention is to provide a kind of image processing system and the image forming method that can utilize the image of the texture of the coarse shape of a kind of ink formation, gloss, accordion.
Image processing system of the present invention is used for being sprayed as drop by ultraviolet hardening ink thus forming image on the recording medium, it is characterized in that, this image processing system comprises: ink jet component, it is mounted on the balladeur train that can move back and forth in a scanning direction, and for spraying ultraviolet hardening ink; Ultraviolet radiation parts, it to be mounted on balladeur train and to be at least configured in the rear, scanning direction of ink jet component, and to the ultraviolet hardening ink irradiation ultraviolet radiation sprayed from ink jet component; And control assembly, it is for controlling ink jet component and Ultraviolet radiation parts; Control assembly can optionally switch following pattern: coarse shape image rock mechanism, on the outlet of balladeur train and at least one in loop, makes ink jet component spray ultraviolet hardening ink, and from Ultraviolet radiation parts irradiation ultraviolet radiation; Glossy image rock mechanism, on the outlet of balladeur train, makes ink jet component spray ultraviolet hardening ink, and from Ultraviolet radiation parts irradiation ultraviolet radiation on the loop of balladeur train; And accordion image rock mechanism, on the outlet of balladeur train, make ink jet component change spray volume and spray ultraviolet hardening ink, and from Ultraviolet radiation parts irradiation ultraviolet radiation on the loop of balladeur train.
In image processing system of the present invention, if when selecting coarse shape image rock mechanism, then after ink jet component ejection ultraviolet hardening ink and then from Ultraviolet radiation parts irradiation ultraviolet radiation.Its result, because the ultraviolet hardening ink of land droplet-like on the recording medium solidified before smoothing, therefore surface is formed concavo-convex, thus forms the image of the coarse shape of diverging light.In addition, if select glossy image rock mechanism, then after having sprayed ultraviolet hardening ink from ink jet component, until balladeur train turns back to same position place again by moving back and forth, can not from Ultraviolet radiation parts irradiation ultraviolet radiation.Its result, due to until in during irradiation ultraviolet radiation, ultraviolet hardening ink smoothing along recording medium diffusion of land droplet-like on the recording medium, therefore will form image that is surface smoothing, that have reflecting feel.In addition, if select accordion image rock mechanism, then identical with glossy image rock mechanism, after having sprayed ultraviolet hardening ink from ink jet component, until balladeur train turns back to same position place again by moving back and forth, can not from Ultraviolet radiation parts irradiation ultraviolet radiation.Therefore, ultraviolet hardening ink smoothing along recording medium diffusion of land droplet-like on the recording medium.Now, spray ultraviolet hardening ink owing to changing spray volume from ink jet component, therefore the smoothness of the ultraviolet hardening ink of land droplet-like on the recording medium becomes uneven according to position difference.Its result, because the ultraviolet hardening ink smoothing of land droplet-like is on the recording medium while produce suitable concavo-convex, therefore forms the image of accordion.So, by optionally switching three image rock mechanism, on the outlet and loop of balladeur train, control ink jet component and Ultraviolet radiation parts according to selected image rock mechanism, and the kind without the need to changing ink just can form the image of texture of coarse shape, gloss, accordion.
In this case, the feature of ink jet component is, comprises the first ink jet component and is configured in second ink jet component at rear, scanning direction of the first ink jet component.So, owing to being coated on the upper strata of the ultraviolet hardening ink from the first ink jet component ejection from the ultraviolet hardening ink of the second ink jet component ejection, therefore being controlled by the ejection of adjustment second ink jet component, the texture of image can be changed.
In addition, preferably, when selecting accordion image rock mechanism, control part makes the second ink jet component interval reject pixel and spray ultraviolet hardening ink.So, when have selected accordion image rock mechanism, spraying ultraviolet hardening ink by rejecting pixel from the second ink jet component interval, the uneven homogenize of the drop density of the ultraviolet hardening ink of land droplet-like on the recording medium can be made.Thus, owing to can make the ink smoothing of the ultraviolet hardening of land droplet-like on the recording medium while produce suitable concavo-convex, therefore, it is possible to reliably form the image of accordion.
And preferably, when selecting glossy image rock mechanism, the spray volume in the single pass of the ultraviolet hardening ink sprayed by the second ink jet component is set to 1400pg/mm by control part 2~ 3400pg/mm 2.So, when selecting glossy image rock mechanism, owing to passing through, by single pass, the spray volume of the ultraviolet hardening ink sprayed from the second ink jet component being configured in rear, scanning direction is increased to per unit area 1400pg/mm 2~ 3400pg/mm 2, make land adjacent ultraviolet hardening ink on the recording medium be easy to mixing each other, therefore, it is possible to promote the smoothing of ultraviolet hardening ink.Thus, in the process that balladeur train is reciprocal, the concavo-convex smoothing of land ultraviolet hardening ink on the recording medium can be made fully.
In addition, preferably, Ultraviolet radiation parts have ultraviolet LED.Such as, if use metal halide lamp etc. cannot switch the Ultraviolet radiation parts of ON/OFF at high speed, then the switching device that shutter and shutter are set separately is needed.Therefore, by ultraviolet LED is used as Ultraviolet radiation parts, the ON/OFF of Ultraviolet radiation can be switched at high speed, therefore without the need to arranging the special devices such as shutter, just only can penetrate ultraviolet when needs irradiation ultraviolet radiation, thus can energy-saving be sought.
Image forming method of the present invention utilizes following image processing system to form image on the recording medium, this image processing system comprises: ink jet component, it is mounted on the balladeur train that can move back and forth in a scanning direction, and for ultraviolet hardening ink is sprayed as drop, Ultraviolet radiation parts, it to be mounted on balladeur train and to be configured in the rear, scanning direction of ink jet component, and to the ultraviolet hardening ink irradiation ultraviolet radiation sprayed from ink jet component, and control assembly, it is for controlling ink jet component and Ultraviolet radiation parts, it is characterized in that, when forming the image of coarse shape, the outlet of balladeur train and at least one in loop make ink jet component spray ultraviolet hardening ink, and from Ultraviolet radiation parts irradiation ultraviolet radiation, when formation has the image of reflecting feel, on the outlet of balladeur train, ink jet component is made to spray ultraviolet hardening ink, on the loop of balladeur train, from Ultraviolet radiation parts irradiation ultraviolet radiation, when forming the image of accordion, on the outlet of balladeur train, ink jet component is made to change spray volume and spray ultraviolet hardening ink, on the loop of balladeur train, from Ultraviolet radiation parts irradiation ultraviolet radiation.
In image forming method of the present invention, when forming the image of coarse shape, after ink jet component ejection ultraviolet hardening ink, and then from Ultraviolet radiation parts irradiation ultraviolet radiation.Its result, because the ultraviolet hardening ink of land droplet-like on the recording medium solidified before smoothing, therefore surface is formed concavo-convex, thus forms the image of the coarse shape of diverging light.In addition, when formation has the image of reflecting feel, after ink jet component ejection ultraviolet hardening ink, until balladeur train turns back to same position place again by moving back and forth, can not from Ultraviolet radiation parts irradiation ultraviolet radiation.Its result, due to until in during irradiation ultraviolet radiation, ultraviolet hardening ink smoothing along recording medium diffusion of land droplet-like on the recording medium, therefore will form image that is surface smoothing, that have reflecting feel.In addition, when forming the image of accordion, identical with glossy image rock mechanism, after having sprayed ultraviolet hardening ink from ink jet component, until balladeur train turns back to same position place again by moving back and forth, can not from Ultraviolet radiation parts irradiation ultraviolet radiation.Therefore, ultraviolet hardening ink smoothing along recording medium diffusion of land droplet-like on the recording medium.Now, spray ultraviolet hardening ink owing to changing spray volume from ink jet component, therefore the smoothness of the ultraviolet hardening ink of land droplet-like on the recording medium becomes uneven according to position difference.Its result, because the ultraviolet hardening ink smoothing of land droplet-like is on the recording medium while produce suitable concavo-convex, therefore forms the image of accordion.So, by controlling ink jet component and Ultraviolet radiation parts on the outlet and loop of balladeur train, the kind without the need to changing ink just can form the image of texture of coarse shape, gloss, accordion.
According to the present invention, the image of the texture of the coarse shape of a kind of ink formation, gloss, accordion can be utilized.

Control part 8 controls by unified the printing control that balladeur train 2, ink gun 6, ultraviolet lamp 4 and ultraviolet lamp 5 carry out ink-jet printer 1.This control part 8 optionally can switch the coarse shape image rock mechanism of the image of the texture forming coarse shape, form the accordion image rock mechanism of the image of the glossy image rock mechanism with the image of reflecting feel and the texture forming accordion.In addition, the selection of image rock mechanism can be carried out according to the printed data of the transmission from RIP22, also can carry out according to the setting of ink-jet printer 1.And, control part 8 is according to selected image rock mechanism, by carrying out the drived control of balladeur train 2, the ink-jet of ink gun 6 controls and the Ultraviolet radiation of ultraviolet lamp 4 and ultraviolet lamp 5 controls, and can form the image of the texture of coarse shape respectively, have the image of the image of reflecting feel and the texture of accordion.In addition, control part 8 is such as configured to using the computer containing CPU, ROM, RAM as main body, and each control of control part 8 described later is by reading predetermined computer software and carry out action to realize based on to the control of CPU on CPU, RAM.
At this, the function of above-mentioned RIP22 is described.
RIP22 is based on the view data of the EPS form utilizing application program 21 to create, TIFF form etc., generate the printed data for the some form utilizing ink-jet printer 1 to carry out printing, and this printed data is sent to ink-jet printer 1 and form image on ink-jet printer 1.This printed data by the ultraviolet hardening ink of the image for each predetermined exploring degree spacing ejection whether, the ejection number of times of ultraviolet hardening ink, the spray volume etc. of ultraviolet hardening ink form.And this printed data is associated with ink gun 6a ~ ink gun 6f respectively, and each pixel of printed data and first sprays each nozzle (not shown) that region A1 and second sprays region A2 is associated.
Usually, this RIP22 generates the printed data making ultraviolet hardening ink at all pixel ejection ink, but process is rejected at the interval also can carrying out the one part of pixel of interval rejecting printed data.It is make the ejection of ultraviolet hardening ink whether from the process changed to nothing for predetermined pixel that process is rejected at interval.In addition, predetermined mask can be utilized specify by the predetermined pixel that interval is rejected, also can utilize random number, predetermined formula etc. specifies.In addition, this interval is rejected process and can be carried out after generation printed data, also can carry out when generating printed data.
At this, as an example, use for all pixel ejection ultraviolet hardening ink and form the printed data that printing concentration is the image of 100%, illustrating that process is rejected at interval.In this case, if owing to maintaining the printed data carried out before the rejecting process of interval, then whether the ejection of ultraviolet hardening ink has been set in all pixels, therefore can for all pixel ejection ultraviolet hardening ink.Therefore, if such as spray the ultraviolet hardening ink of 100% concentration from the ink gun 6e the second ejection region A2 and ink gun 6f according to the printed data before the rejecting process of interval, then print concentration and become 200%, the drop density of ultraviolet hardening ink becomes roughly even.On the other hand, if carry out interval to reject process, then due to ultraviolet hardening ink ejection whether for the one part of pixel in printed data from changing to nothing, ultraviolet hardening ink can not be sprayed for one part of pixel.Therefore, if reject the printed data of process from the second ejection region A2 ejection ultraviolet hardening ink according to having carried out interval, ultraviolet hardening ink then owing to spraying to medium can not spray one part of pixel, therefore print concentration less than 200%, the drop density of ultraviolet hardening ink becomes uneven.
And generated printed data, when making ink-jet printer 1 form the image of coarse shape and the glossiness texture of tool, is sent to ink-jet printer 1 by RIP22 as former state.On the other hand, RIP22 is when making ink-jet printer 1 form the image of the texture of accordion, the printed data that region A 1 is associated is sprayed as with first, generated printed data is sent to ink-jet printer 1 as former state, spray as with second the printed data that region A2 is associated, the printed data (can not from the printed data of the one part of pixel ejection ultraviolet hardening ink eliminated by interval) having carried out interval and reject process is sent to ink-jet printer 1.
And, about the control part 8 of ink-jet printer 1, if select coarse shape image rock mechanism, then on the outlet of balladeur train 2 and at least one in loop, spray ultraviolet hardening ink according to the printed data sent from RIP22 from the first ejection region A 1 and second ejection region A2, and from ultraviolet lamp 4 and ultraviolet lamp 5, the one injection ultraviolet at the moving direction rear that is at least configured in balladeur train 2.In addition, in the present embodiment, be set to penetrate ultraviolet from both ultraviolet lamp 4 and ultraviolet lamp 5 on the outlet of balladeur train 2 and the both direction in loop.
In addition, about control part 8, if be chosen as glossy image rock mechanism, then on the outlet of balladeur train 2, spray ultraviolet hardening ink from the first ejection region A1 and second ejection region A2 according to the printed data from RIP22 transmission, and penetrate ultraviolet from least one of ultraviolet lamp 4 and ultraviolet lamp 5 on the loop of balladeur train 2.In addition, in the present embodiment, ink-jet printer 1 is set on the loop of balladeur train 2, makes ultraviolet only from the device that ultraviolet lamp 4 penetrates.
In addition, about control part 8, if be chosen as accordion image rock mechanism, then from first ejection region A1 and second ejection region A2 spray ultraviolet hardening ink with changing spray volume according to the printed data from RIP22 transmission in the outlet of balladeur train 2, and penetrate ultraviolet from least one of ultraviolet lamp 4 and ultraviolet lamp 5 on the loop of balladeur train 2.In addition, in the present embodiment, be set to according to utilizing RIP22 to carry out the printed data of interval rejecting process and spray ultraviolet hardening ink from the second ejection region A2 on the outlet of balladeur train 2, and only penetrate ultraviolet from ultraviolet lamp 4 on the loop of balladeur train 2.
Then, the action of ink-jet printer 1 is described with reference to Fig. 3 A and Fig. 3 B.Fig. 3 A and Fig. 3 B is the figure of the action case of the ink-jet printer represented in coarse shape image rock mechanism, and Fig. 3 A represents the outlet of balladeur train, and Fig. 3 B represents the loop of balladeur train.Fig. 4 A and Fig. 4 B is the figure of the action case of the ink-jet printer represented in glossy image rock mechanism, and Fig. 4 A represents the outlet of balladeur train, and Fig. 4 B represents the loop of balladeur train.Fig. 5 A and Fig. 5 B is the figure of the action case of the ink-jet printer represented in accordion image rock mechanism, and Fig. 5 A represents the outlet of balladeur train, and Fig. 5 B represents the loop of balladeur train.In addition, the printing action of illustrated below ink-jet printer 1 utilizes the control of control part 8 to carry out.That is, in control part 8, the handling part (not shown) be made up of CPU etc. is according to the program be recorded in the storage devices such as R OM, and unification controls balladeur train 2, ink gun 6, ultraviolet lamp 4 and ultraviolet lamp 5, thus carries out following process.
First, with reference to Fig. 3 A and Fig. 3 B, the situation that have selected coarse shape image rock mechanism is described.
In coarse shape image rock mechanism, first, RIP22 generates printed data according to the view data utilizing application program 21 to generate.Now, RIP22 does not carry out the interval rejecting process of printed data.And this printed data is sent to ink-jet printer 1 by RIP22.On the other hand, if ink-jet printer 1 obtains the printed data sent from RIP22, then make balladeur train 2 move back and forth on the S of scanning direction, thus scan.
And, as shown in Figure 3A, on the outlet of the balladeur train 2 of balladeur train 2 forward movement on the S of scanning direction, drive the first ejection region A1 and second ejection region A2, the drop of ultraviolet hardening ink is sprayed from the first ejection region A1 and second ejection region A2, and lights ultraviolet lamp 4 and ultraviolet lamp 5.So, from first ejection region A1 and second ejection region A2 spray droplet-like ultraviolet hardening ink land are on medium after and then illuminated from ultraviolet lamp 4 and ultraviolet lamp 5 injection ultraviolet.Its result, because the ultraviolet hardening ink of the droplet-like of land on medium solidified before smoothing, therefore surface is formed as concavo-convex, thus forms the image of the coarse shape of diverging light.
On the other hand, as shown in Figure 3 B, identical with the outlet of balladeur train 2, on the loop of balladeur train 2 balladeur train 2 of reverse movement on the S of scanning direction, drive the first ejection region A1 and second ejection region A2, the drop of ultraviolet hardening ink is sprayed from the first ejection region A1 and second ejection region A2, and lights ultraviolet lamp 4 and ultraviolet lamp 5.Thus, identical with the outlet of balladeur train 2, form the image that surface is coarse shape.
Then, the situation that have selected glossy image rock mechanism is described with reference to Fig. 4 A and Fig. 4 B.In glossy image rock mechanism, first, RIP22 generates printed data according to the view data utilizing application program 21 to generate.
Now, RIP22 becomes 1400pg/mm respectively with the spray volume in the single pass (1pass) of the ultraviolet hardening ink (transparent ink) sprayed from ink gun 6e and the ink gun 6f of the second ejection region A2 2~ 3400pg/mm 2mode generate printed data.Therefore, 2800pg/mm is become from total spray volume of the ultraviolet hardening ink of ink gun 6e and ink gun 6f ejection 2~ 6800pg/mm 2.And then, when forming image with many pass, become 1400pg/mm from each total spray volume of the ultraviolet hardening ink of ink gun 6e and ink gun 6f ejection 2~ 3400pg/mm 2pass several times.Such as, when forming image with 12pass, the ultraviolet hardening ink sprayed from ink gun 6e and ink gun 6f respectively becomes 1400pg/mm 2~ 3400pg/mm 2the 16.8ng/mm of 12 times 2~ 40.8ng/mm 2if merge the ultraviolet hardening ink sprayed from ink gun 6e and ink gun 6f, then become 33.6ng/mm 2~ 81.6ng/mm 2.In addition, method for making the spray volume of the ultraviolet hardening ink of per unit area increase can be any means, such as, the method etc. making the method for the drop amount of each drop sprayed from ink gun 6e and ink gun 6f increase by the translational speed of reduction balladeur train 2, improve the method for the ejection density of the drop sprayed from ink gun 6e and ink gun 6f, increase the quantity of the ink gun be mounted in the second ejection region A2 can be enumerated.In addition, the ultraviolet hardening ink (color ink) sprayed from ink gun 6a ~ ink gun 6d suitably sets this spray volume according to formed coloured image.
And this printed data is sent to ink-jet printer 1 with rejecting process by the interval that RIP22 does not carry out printed data.On the other hand, if ink-jet printer 1 obtains the printed data sent from RIP22, then make balladeur train 2 move back and forth on the S of scanning direction, thus scan.
And, as shown in Figure 4 A, on the outlet of the balladeur train 2 of balladeur train 2 forward movement on the S of scanning direction, drive the first ejection region A1 and second ejection region A2, spray the drop of ultraviolet hardening ink from the first ejection region A1 and second ejection region A2, and extinguish ultraviolet lamp 4 and ultraviolet lamp 5.Now, the ink-jet carrying out ink gun 6e and ink gun 6f controls, and becomes 1400pg/mm respectively to make the spray volume the single pass (1pass) of the transparent ink sprayed from ink gun 6e and the ink gun 6f of the second ejection region A2 2~ 3400pg/mm 2mode.Therefore, total spray volume of the ultraviolet hardening ink sprayed from ink gun 6e and ink gun 6f in single pass (1pass) becomes 2800pg/mm 2~ 6800pg/mm 2.So, spread and sink in out and lower thickness on medium gradually after land are on medium from the ultraviolet hardening of the droplet-like of the second ejection region A2 ejection is black, thus the concavo-convex smoothing on surface.And, because total spray volume of ultraviolet hardening ink is formed as 2800pg/mm 2~ 6800pg/mm 2, the drop density of ultraviolet hardening ink is higher, is therefore easy between adjacent drop, produce contact and mixing, thus promotes smoothing.
On the other hand, as shown in Figure 4 B, on the loop of balladeur train 2 balladeur train 2 of reverse movement on the S of scanning direction, stop the driving of the first ejection region A1 and second ejection region A2 and stop the ejection of ultraviolet hardening ink, light ultraviolet lamp 4, and extinguish ultraviolet lamp 5.So, although on the outlet at balladeur train 2 ejection and land on medium ultraviolet hardening ink irradiation ultraviolet radiation and ultraviolet hardening ink solidification, but from after spraying ultraviolet hardening ink in the outlet of balladeur train 2 until on the loop of balladeur train 2 during irradiation ultraviolet radiation in, the ultraviolet hardening ink fully smoothing of land on medium.And, because ultraviolet hardening ink is so cured with smoothing state, be therefore formed with the image with reflecting feel.
Then, the situation that have selected accordion image rock mechanism is described with reference to Fig. 5 A and Fig. 5 B.In accordion image rock mechanism, first, RIP22 generates printed data according to the view data utilizing application program 21 to generate.Now, RIP22 for and second spray printed data that region A2 is associated and carry out interval and reject and process.Then, this printed data is sent to ink-jet printer 1 by RIP22.On the other hand, if ink-jet printer 1 obtains the printed data sent from RIP22, then make balladeur train 2 move back and forth on the S of scanning direction, thus scan.
Then, as shown in Figure 5A, on the outlet of the balladeur train 2 of balladeur train 2 forward movement on the S of scanning direction, drive the first ejection region A1, spray the drop of ultraviolet hardening ink from the first ejection region A1 according to printed data, drive the second ejection region A2, reject the printed data after process according to interval and spray from second the drop that region A2 sprays ultraviolet hardening ink, and extinguish ultraviolet lamp 4 and ultraviolet lamp 5.So, reject pixel from the second ejection A2 interval, region and spray the drop of ultraviolet hardening ink, ultraviolet hardening ink can not be sprayed for the pixel eliminated by interval.And, identical with glossy image rock mechanism, spread and sink in out at medium gradually after land are on medium from the ultraviolet hardening ink of the droplet-like of the first ejection region A1 and second ejection region A2 ejection, lower thickness.Now, due to can not from the second ejection region A2, the pixel ejection ultraviolet hardening ink that eliminated by interval but become perforate state, the drop density of the ultraviolet hardening ink therefore on medium is by uneven homogenize, and the smoothness of ultraviolet hardening ink also becomes uneven according to position difference.Therefore, the ultraviolet hardening ink smoothing of the droplet-like of land on medium is while produce suitable concavo-convex.
On the other hand, as shown in Figure 5 B, on the loop of balladeur train 2 balladeur train 2 of reverse movement on the S of scanning direction, stop the driving of the first ejection region A1 and second ejection region A2 and stop the ejection of ultraviolet hardening ink, light ultraviolet lamp 4 and extinguish ultraviolet lamp 5.So, although on the outlet at balladeur train 2 ejection and land on medium ultraviolet hardening ink irradiation ultraviolet radiation and make ultraviolet hardening ink solidification, but from after spraying ultraviolet hardening ink in the outlet of balladeur train 2 until on the loop of balladeur train 2 during irradiation ultraviolet radiation, ultraviolet hardening ink by smoothing while produce suitable concavo-convex.And, because ultraviolet hardening ink so to produces suitable concavo-convex state cured, therefore form the image of the texture of accordion.
So, according to the present embodiment, by optionally switching coarse shape image rock mechanism, glossy image rock mechanism and accordion image rock mechanism, the first ejection region A1, the second ejection region A2, ultraviolet lamp 4 and ultraviolet lamp 5 is controlled according to each image rock mechanism, just can with the image of the texture of the coarse shape of a kind of ultraviolet hardening ink formation, gloss, accordion without the need to the kind changing ultraviolet hardening ink.
And, when have selected coarse shape image rock mechanism, by spraying ultraviolet hardening ink from the first ejection region A1 and second ejection region A2, image can be improved and form speed.In addition, when have selected glossy image rock mechanism, by increasing the spray volume of the ultraviolet hardening ink in single pass, the smoothing of ultraviolet hardening ink can be promoted.In addition, when have selected accordion image rock mechanism, spraying ultraviolet hardening ink by rejecting pixel from the second ejection A2 interval, region, the uneven homogenize of the drop density of the ultraviolet hardening ink of the droplet-like of land on medium can be made.Thus, due to the smoothing of the ultraviolet hardening of the droplet-like of land on medium ink can be made to produce suitable concavo-convex, therefore, it is possible to suitably form the image of accordion.
In addition, when have selected glossy image rock mechanism, due to by the spray volume of ultraviolet hardening ink sprayed from each ink gun 6 of the second ejection region A2 being configured in S rear, scanning direction in single pass is increased to per unit area 1400pg/mm 2~ 3400pg/mm 2, make the drop of the adjacent ultraviolet hardening ink of land on medium be easy to mixing each other, therefore, it is possible to promote the smoothing of ultraviolet hardening ink.Thus, in the process that balladeur train is reciprocal, the concavo-convex smoothing of the ultraviolet hardening ink of land on medium can be made fully.
And then, owing to passing through to use UVLED in ultraviolet lamp 4 and ultraviolet lamp 5, the ON/OFF of Ultraviolet radiation can be switched at high speed, therefore without the need to be arranged on use cannot switch the metal halide lamp etc. of the ON/OFF of Ultraviolet radiation at high speed when required shutter etc. special device, just only can penetrate ultraviolet when needs irradiation ultraviolet radiation, thus can energy-saving be sought.
Above, describe preferred embodiment of the present invention, but the present invention is not limited to above-mentioned embodiment.Such as, in the above-described embodiment, describe and on the outlet and loop of balladeur train 2, spray ultraviolet hardening ink in coarse shape image rock mechanism, but such as shown in Fig. 6 A and Fig. 6 B, also can be set to outlet and loop any one on spray ultraviolet hardening ink.In this case, on the outlet of the balladeur train 2 of balladeur train 2 forward movement on the S of scanning direction, as shown in Figure 6A, drive the first ejection region A1 and second ejection region A2, spray the drop of ultraviolet hardening ink from the first ejection region A1 and second ejection region A2, and light ultraviolet lamp 4 and ultraviolet lamp 5.On the other hand, on the loop of balladeur train 2 balladeur train 2 of reverse movement on the S of scanning direction, as shown in Figure 6B, stop the driving of the first ejection region A1 and second ejection region A2, and light ultraviolet lamp 4 and ultraviolet lamp 5.In addition, on the loop of balladeur train 2, irradiation ultraviolet radiation is the solidification in order to promote ultraviolet hardening ink, therefore also can irradiation ultraviolet radiation on the loop of balladeur train 2 especially.
In addition, in the above-described embodiment, describe in accordion image rock mechanism, reject process by the interval of carrying out printed data on RIP22 and reject pixel by control part 8 interval and spray ultraviolet hardening ink from the second ejection region A2, but also can be set to the interval of carrying out printed data in control part 8 rejects process.
In addition, in the above-described embodiment, describe in accordion image rock mechanism, the drop of ultraviolet hardening ink is sprayed by rejecting pixel from the second ejection A2 interval, region, thus make the spray volume change of the ultraviolet hardening ink sprayed from ink gun 6, but any parts also can be utilized to make the spray volume change of the ultraviolet hardening ink sprayed from the second ejection region A2.Such as, the spray volume increase and decrease of the ultraviolet hardening ink made in each pixel can be also set to.
In addition, in the above-described embodiment, describe the nozzle rows the first ejection region A1 of ejection color ink being set to latter half on direction of feed F, second ejection region A2 of the transparent ink of ejection is set to the nozzle rows of first half by the direction of feed F of ink gun 6, but also the first ejection region A1 and second ejection region A2 can be set to the whole region of nozzle rows.In this case, because the first ejection region A1 and second ejection region A2 is in same position on direction of feed F, the ejection of color ink and the ejection of transparent ink is therefore separately carried out.That is, first, to direction of feed F pumped (conveying) medium, the printing color image from the first ejection region A1 ejection color ink, afterwards, makes medium once return.Then, again to direction of feed F pumped (conveying) medium, spray transparent ink from the second ejection region A2, be coated with transparent ink on the surface of coloured image.On the other hand, inferior in the situation being printed with coloured image, without the need to printing color image, not spray color ink from the first ejection region A1, but spray transparent ink from the whole region of the nozzle rows the second ejection region A2, i.e. ink gun 6e and ink gun 6f.
In addition, in the above-described embodiment, describe and only spray ultraviolet hardening ink from the first ejection region A1 and second ejection region A2 of ink gun 6, such as, also can be set to from the nozzle rows of ink gun 6a ~ ink gun 6d, to be configured in region ejection on first half relative to the transparent ink sprayed from the second ejection region A2 at direction of feed F be the color ink of 5 below volume %.Thus, owing to mixing the color ink of 5 below volume % in single pass in transparent ink, therefore, it is possible to form the film of the transparent ink of colorize.
In addition, in the above-described embodiment, describe and only spray a kind of ink from each ink gun 6, but also can form multiple row nozzle rows on the S of scanning direction and change the kind of the ink of ejection for every row nozzle rows.In addition, describe on head unit 3 with every look only the mode of a group carry the ink gun of ejection color ink, but also can be set to and carry ink gun in the mode of every look many groups.
In addition, in the above-described embodiment, not specifying especially from the forward mobile handoff of balladeur train 2 is the action of oppositely movement, but such as when have selected glossy image rock mechanism, simultaneously be also because of the interaction between medium and ink etc. cannot fully smoothing when, also can after the forward mobile end of balladeur train 2, after the standby scheduled time, start reverse movement.Thus, because ultraviolet hardening ink is spread and sunk in out further, therefore, it is possible to promote smoothing further.
In addition, in the above-described embodiment, describe to be printed by printing zone at twice, but do not limited by number.Such as, when point to be printed by printing zone for 12 times, using by the nozzle rows of ink gun 6 divided by the width (passing through width) obtained as 12 by number as a conveying capacity of medium, print identical printing zone with the scanning of 12 times (by numbers).
