Fig. 3 illustrates the major part of structure shown in Fig. 2 block diagram as functional module.Module corresponding to the equipment shown in Fig. 2 is represented by same Reference numeral.Referring to Fig. 3, the user uses input unit (keyboard and mouse) to import various manual command.CPU (CPU) 303 can be controlled various operation and execution and be stored in wherein program.Read-only memory (ROM) 304 is stored necessary image processing etc. in advance.Random-access memory (ram) 305 interim stored programs and the view data that will handle by CPU303.Hard disk (HD) 308 storage will be sent to program and the view data of RAM305 etc., and the view data crossed of stores processor.Data can be by from compact disk (CD, compact disk) 301 reads or is written to compact disk (CD) 301, compact disk 301 is a kind of of exterior storage medium, and exterior storage medium for example is can write down CD (CD-R), can rewrite CD (CD-RW) or digital versatile dish (DVD).When the program of image editor, Printer Information etc. was stored among the CD301 etc., as required, program or information were installed to HD308 and are sent to RAM305.
Fig. 4 is the flow chart that the processing of carrying out with Fig. 2 and the structure shown in Fig. 3 of first embodiment is shown.The computer executable program of the processing of the flow chart shown in Fig. 4 has been described in storage in advance in ROM304.Selectively, another aspect of the present invention can be by reading and provide the program that is stored among the HD308 to RAM305, and carried out this program and realized by CPU303.
With reference to flow chart shown in Figure 4, the processing that first embodiment is carried out describes.In step S401, obtain the type of print media.In the processing of step S401, for example, as shown in figure 11, the user interface that service routine provides, the user visually judges the kind of print media and the kind of selective printing medium from tabulation.The print media kind that obtains is stored among the RAM305.
In step S402, the print media kind of judging based on middle step S401 and as the facility information of the printer 204 of output equipment, the activation bit of retrieval printer 204.From the activation bit of retrieval, obtain reference information corresponding to print media kind and printer 204.The reference information that obtains is stored among the RAM305.If the size of reference information is big, reference information is stored among the HD308 etc.
In step 403, based on the reference information that in step S402, obtains, generate total painted dosage and judge small pieces, and the total painted dosage that printer 204 will generate judges that small pieces print on the print media of expectation.As shown in Figure 5, total painted dosage judges that small pieces comprise a plurality of images with total painted dosage (as painted dosage 1～4) progressively different in predetermined scope.In addition, each in a plurality of images comprises a plurality of print areas, change at described print area intermediate-resolution (line number), thereby the gap of linear print part and non-printing portion alternately exists with linear mode.In order to realize simpler judgement, the printing portion in the print area has identical resolution.By equally dividing central shaft is preset range by the maximum painted dosage of reference information indication, and uses the binary system parameter progressively to change painted dosage, a plurality of images is generated as the image of a plurality of painted dosage of indication.Because image is generated as a plurality of progressively different painted dosage, thus comparison can be carried out simply, thus reach the judgement of the painted dosage of simpler maximum.Judge that at the total painted dosage of this generation and output small pieces needn't be identical with small pieces shown in Figure 5.For example, as shown in figure 10, the image with progressively different total painted dosage can non-printing portion cruciferous.Each printing portion of small pieces shown in Fig. 5 or 10 and non-printing portion width can by the expectation mode set.Can set width based on the reference information that obtains according to the combination of print media kind and colorant type among the kind of the print media that obtains in the step 401 and the step S402.For example, when relating to the processing resolution of printer, because in conjunction with causing a large amount of inks to ooze out, so carry out the processing that increases gap length.
In addition, the small pieces shown in Figure 12 can be as the small pieces of judging total painted dosage.Small pieces shown in Figure 12 are a kind of thick printing small pieces (that is, a kind of three-dimensional small pieces), wherein, use the different total painted dosage of combination output of multiple colouring agent.For the use of small pieces shown in Figure 12, can observe the deterioration of the granularity that caused colouring agent is assembled when print media can not be accepted colouring agent.In the combination of colouring agent, when the small pieces shown in Figure 12 are output, for example, according to based on print media and colouring agent in conjunction with defined acceptance (infiltrations) speed, the colouring agent of low acceptance (infiltration) speed is preferentially used.In addition, the combination of colouring agent can judge according to the reference information of each device type of obtaining among the step S402, and reference information comprises in the information of acceptance (infiltration) speed of the information of viscosity of every kind of colouring agent and every kind of print media at least a.
Obviously, for example, as shown in figure 13, by being output in conjunction with the formed image of above-mentioned small pieces.Can change the combination or the arrangement of small pieces in the mode of expectation.
In step S404, judge small pieces according to the total painted dosage of in step S403, exporting, the maximum painted dosage of the print media of input expectation.The user is the maximum painted dosage of perception from the output result, and import maximum painted dosage with input unit (keyboard and mouse) 313.To use small pieces for example shown in Figure 10 that maximum painted dosage is described.Maximum painted dosage is the painted dosage corresponding to the image that can clearly judge the non-printing portion of cross.In addition, when the maximum painted dosage of input, expectation is ready to show the indicating device (indicator) of the damage degree of cross image.In this indicating device, can distinguish damage degree and the damage degree of printing under the photograph situation under the ready-to-print text situation.
After the processing of step S404 finished, this processing sequence was done.
For above-mentioned processing controls, even for not being driven the print media that device is supported, the user that printing device is had a technological know-how seldom is executable operations and judge the maximum painted dosage that reaches the optimal printing result simply.
Among first embodiment, in step S401, the user is from visually judging the kind of print media.Yet, no matter the kind of print media, or the attribute of print media can be by using as glossmeter, spectroreflectometer or microscope etc. can be carried out measurement for the transducer of certain value with the Feature Conversion of surface of print media and obtain.When system carries out judgement automatically according to obtaining attribute, also can reach similar advantage by realizing aspect of the present invention.
In step S402, reference information needn't obtain from the driver being installed in computer 202.Reference information can obtain from exterior storage medium, as CD310.In addition, computer 202 can be transmitted in the print media kinds of information that obtains among the step S401 and as the facility information of the printer 204 of output equipment, and can obtain to transmit the result.In addition, print image not only can be generated by computer 202, also can obtain by the exterior storage medium of for example CD310.
In addition, although total to be used for the painted dosage of step S403 be by using as the maximum painted dosage definition at the center of preset range, but the central shaft of preset range also can move by the mode of expectation.In addition, although in step S403, total four types of painted dosage are arranged on total painted dosage and judge in the small pieces, but obviously total painted dosage judges that small pieces needn't comprise four types of total painted dosage.In addition, the gap needs not to be nonprinting region.The gap can be not use colouring agent print media to be carried out the part of handling.
In addition, in step S404, can automatically perform judgement about the painted dosage of maximum.For example, scanner 201 grades can automatically perform judgement after reading and printing die image and extract the non-printing portion of cross.In addition, being installed in after transducer in the printer 204 reads small pieces shown in Figure 5 of for example CCD (not shown), can generate the acutance data of every kind of painted dosage, thereby maximum painted dosage can be judged automatically based on these acutance data.The standard of judging can rely on be printed to as if text still be photo and changing.For example, can different resolution thresholds be set for text and photo.Selectively, estimate that resolution relies on text or photo changes.Changing criterion suitably makes and can carry out the judgement that each image gets the painted dosage of best maximum.
In addition, print small pieces for thick (solid) of the combination of using colouring agent shown in Figure 12, when the operator watched small pieces, the operator can import the granularity of the sensation of granularity as the colouring agent assembly.Selectively, can calculate the granularity of the image that scanner or C CD transducer caught, thereby can judge whether predetermined threshold value is exceeded.

In step S1701, generate total painted dosage and judged small pieces, the total painted dosage of generation judges that small pieces are outputed on the expectation recording medium by the interface (I/F) that allows communication between computer 202 and the printer 204 by printer 204.
Figure 18 and Figure 19 illustrate the example that total painted dosage is judged small pieces.Total painted dosage shown in Figure 18 judges that small pieces comprise a plurality of images with predeterminated level scope of total painted dosage.In each of a plurality of images, selectively there be recording section and non-recording section with linear mode with different resolution (line number).Total painted dosage shown in Figure 19 judges that small pieces comprise a plurality of images with predeterminated level scope of total painted dosage, and each in a plurality of images comprises the non-recording section of cross.Total painted dosage judges that small pieces needn't be configured to Figure 18 or shown in Figure 19.Can use the total painted dosage of any kind to judge small pieces, as long as image comprises recording section and non-recording section adjacent to one another.Though Figure 18 and Figure 19 illustrate four types total painted dosage, can also use the total painted dosage of two kinds or three types, or five kinds or more eurypalynous total painted dosage.In addition, the image of record needn't be generated by computer 202.The image of record can obtain by exterior storage medium or the transfer equipment 314 of for example CD310 or FD311.
After image was recorded, this processing proceeded to step S1702.
In step S1702, judge small pieces according to the total painted dosage of exporting among the step S1701, maximum total painted dosage of the recording medium of input expectation.About the total painted dosage of maximum, for example, judge small pieces according to the total painted dosage shown in Figure 19, the threshold value of the non-printing portion of cross is clearly discerned in user's perception, and uses input unit (keyboard and mouse) 313 these threshold values of input.Can directly import maximum total painted dosage, maybe can be input as the value or the symbol of each small pieces definition.
When the maximum total painted dosage of input, expectation is ready to show the indicating device of the damage degree of cross part.In indicating device, the damage degree under damage degree under the recording text situation and the record photograph situation can be to prepare separately.Maximum total painted dosage of input is stored among the ROM304.
In step S1703,, retrieve one or two and have the existing LUT that equals or approach total painted dosage of maximum total painted dosage based on maximum total painted dosage of importing among the step S1702.
Figure 20 illustrates a storage and shows the existence of pre-prepd existing LUT (existing color-separated table) or the tabulation of non-existent data.For example, existing LUT is present in the driver that is contained in the computer 202, and can be used as the exterior storage medium issue, as CD310 or FD311, maybe can obtain by transfer equipment 314.Selectively, existing LUT can issue as exterior storage medium by transfer equipment 314.
Referring to Figure 20, as existing LUT, for example, maximum painted dosage is that 180 table is present in storage medium etc., does not exist and maximum painted dosage is 200 table.When maximum total painted dosage of importing among the step S1702 is " 200 ", " 220 " or " 240 ",, retrieve corresponding existing LUT owing to exist for the existing LUT of the total painted dosage of corresponding maximum.Relatively, when the total painted dosage of maximum " 180 " or " 260 " are transfused to or be not present in the table shown in Figure 20 corresponding to the value of the total painted dosage of input, because corresponding existing LUT do not exist, so retrieve one or more available LUT.For example, retrieve corresponding near the existing LUT of total painted dosage of input value or corresponding to two LUT of total painted dosage that input value is clipped in the middle.The information stores of the LUT that retrieves is in ROM304 or HD308.Retrieving a LUT, still will to retrieve two LUT be predetermined according to the explanation of color-separated system for example.
In step S1704,, be created on the best LUT of the recording medium of the expectation that is used to export among the step S1701 based on the LUT that retrieves among the step S1703.When the LUT that in step S1703, retrieves two types, based on the generation of carrying out LUT corresponding to the maximum painted dosage of the LUT that retrieves by interpolation.For example, use the maximum painted dosage of the existing LUT retrieve and the maximum painted dosage of the recording medium of the expectation imported carries out interpolation in step S1702.In other words, be used as the ratio of inner interpolation corresponding to the difference between the total painted dosage of the total painted dosage of each LUT that retrieves and input, the corresponding gridden data of the grid point by using same position is carried out the gridden data that interpolation is obtained new LUT by this ratio.
When in step S1703, retrieving LUT,, the gridden data execution of the LUT that retrieves etc. is doubly handled, thereby carried out the coefficient multiplication with the ratio of total painted dosage of painted dosage of maximum and the LUT that retrieves.The LUT that obtains is stored among ROM304 or the HD308, and is arranged so that can be printed the machine driver when processing finishes uses.
After step S1704 finished dealing with, a series of processing finished.
The 5th embodiment
Though the user judges in the step S1702 of the 4th embodiment and imports maximum total painted dosage, judges and needn't be carried out by the user.
Apparently, can automatically perform judgement among the step S1702.For example, after scanner 201 grades read the record die image shown in Figure 19 and extracted the non-recording section of cross, judgement can automatically perform.In addition, after the CCD in being installed in printer 204 etc. reads small pieces shown in Figure 180, can generate the acutance data of each painted dosage, thereby judge maximum painted dosage automatically based on the acutance data.The standard of judging can according to write down to as if text still be photo and changing.For example, can provide different resolution thresholds for text and photo.
The 6th embodiment
Though the input information on Qi Wang the recording medium is the data of maximum painted dosage in the aforementioned embodiment, this information needs not to be the data of maximum painted dosage.
Figure 21 illustrates the block diagram according to the color-separated image processing structure of the 6th embodiment.In handling according to the color-separated of the 6th embodiment, maximum painted dosage decision chart generation unit 801 outputs are used to judge the chart of the maximum painted dosage of the recording medium of being selected by medium kind acquiring unit 803.Maximum painted dosage acquiring unit 802 uses this chart to obtain the maximum painted dosage of the recording medium of expectation.Then, medium kind acquiring unit 803 is from for example obtaining the medium kind glossy paper, half machine-glazed paper and the art paper.Based on recording medium kind of obtaining and maximum painted dosage, when at least one existing LUT of reference record medium, new LUT generation unit 804 generates new LUT.
