Description
Technical field
The application is related to the multiple bases based on subregion in a kind of textile digit printing（Passage color）Color model is set up
Method and application process（ICC Profile preparation methods）.
Background technology
Generally, the actual color effect of textile digit printing exists certain poor with the effect shown on computer screen
Different, this with fabric and ink used except having outside the Pass, main reason is that the colour gamut of distinct device is different, the energy of apparent color
Power is different, so as to cause the color that computer screen display color goes out with actual spray printing not fully.In order to ensure difference
Consistency of colour between equipment, it is necessary to which color management is carried out to distinct device.The basic ideas of color management are to select first
One is selected with device-independent color space as conversion platform, then each equipment to whole image system is characterized
Description, forms device characteristics file, and the color space and device-independent standard of equipment are finally set up using device characteristics file
The corresponding relation that color space (i.e. conversion platform) is determined, so as to realize that color rendering is consistent.Mainly include three big major parts：
Device characteristics file (ICC Profile), characteristic file connection space (PCS, i.e. conversion platform) and color management module
(ColorManagement Modules, abbreviation CMM).Wherein ICC Profile are the core of color management, its recording equipment
Color characteristics and gamut range necessary believe there is provided be transformed into needed for device independent color space by the equipment color data
Breath.For example by the image on display by printer output, CMM is first with the Profile of display by the color of image
Data are transformed into Lab space by rgb space, and color data is transformed into CMYK by Lab space further according to the Profile of printer
Space, printer utilizes the cmyk data output image now obtained.By changing twice, the color of printer output image can
More consistent effect is obtained with the color shown by display, that is, reaches color accurate delivery between different images equipment,
Specific color data conversion can be illustrated with Fig. 1.
In recent years, the CMYK4 color inks aquaporin of standard printer can not meet high accuracy prints, air brushing, Yi Jifang
Digit printing occasion is knitted, for the high saturation of the color of printout and in high precision, it is necessary in the CMYK four primaries ink of script
Increase such as some other ink channels on the basis of aquaporin, such as red (R), green (G) royalblue (B), orange (O) etc.,
Formed such as the colors of CMYKOB six, the multiple bases ink channel combination such as colors of CMYKRCB seven.Though extra ink adds and improves printed product
Matter, but also band problems.In the multiple bases colour mixture model of standard, the composition of any point color P, P points in colour mixture model
Primary colours number is exactly ink channel N, such as four primary, and by C, M, Y, K, these four inks are constituted P points；For six-basic-color, P points by
This six kinds of ink compositions of C, M, Y, K, O, B.It can be seen that, with the primary colours number increase of ink channel, the composition ink of the P points of colour mixture model
Amount is also continuously increased.
Digit printing is that different colours ink dot is sprayed at into fabric colour generation by multigroup shower nozzle, has substantial amounts of ink dot and exists
It is overlapping on fabric.With the increase of ink channel, the composition ink amount of the ink dot of colour mixture also increases, the folded color probability between ink dot
Gradually increase, this also implies that the colour mixture relation between digit printing ink dot is complicated.Such as during paper printing, due to
The transparency of ink, ink dot, which folds color, can produce the 3rd color, the M of such as equivalent（It is pinkish red）With Y（It is yellow）Mixing can obtain R（It is red）.And it is right
For textile digit printing, due to the particularity of weaving face fabric, fabric is first adsorbed after a kind of ink, then be superimposed absorption it is other
Color is difficult, therefore the color blending effect that the superposition of many inks can not be envisioned, and folds the Y of color equivalent when such as first printing M (magenta) again
(yellow) fold color obtain be intended to reddish violet, if first print Y (yellow) be superimposed again equivalent M (magenta) fold color obtain be inclined to
It is orange；As shown in Figure 2.
The CMYKOB multiple bases colour mixture models of standard are complete colour mixture model combinations, i.e., all colours are involved in colour mixture, mix
The maximum ink amount that color is produced can reach 600% (based on each passage ink amount maximum 100%), and color is folded except increasing considerably ink dot
Probability outside, also considerably beyond general weaving face fabric can bear maximum ink amount（About between 240% ~ 300%）, total ink is measured too high
The increase of surface ink water-water reactor accumulated amount can be caused, causes ink imbibition ink overflow on fabric, the pattern of textile digit printing is influenceed
Precision.
In summary, although the multiple bases colour mixture color model gamut range of standard has increased, excessive ink leads to
Road participates in colour mixture and causes ink dot to fold color relation confusion, and folded color is more, and colour generation is more inaccurate, the stability and standard of deleterious effects on color
True property, is accomplished by providing a kind of new colour mixture model for these problems.

Referring to Fig. 1~Fig. 6, the present embodiment is based on subregion multiple bases color（Colour mixture）Modular concept：
The multiple bases colour mixture model of standard is complete colour mixture model combination, i.e., all colours are involved in colour mixture.In many bases of standard
In color contamination color model, any point color P, P composition primary colours number are exactly ink channel number in colour mixture model, such as four bases
Color, by C, M, Y, K, these four inks are constituted P points；For six-basic-color, by C, M, Y, K, O, B, this six kinds of inks are constituted P points.With
Primary colours number N increases, colour mixture ink amount increase, add ink dot and fold color probability, folded color is more, and colour mixture relation is more chaotic, influence colour generation
Accuracy.
N color colors of the invention based on subregion（Colour mixture）Model：
Color space is divided into by primary colours（N-1）Individual region（Note：K is not involved in subregion）, any point color P in each subregion, its
Constitute color by two kinds of adjacent primary colours of the form and aspect for constituting subregion plus K colour cells into and unrelated with total primary colours number N.Color colour mixture
Situation is generated according to different zones, if any point P only has C, B, K primary colours composition in CBK regions, if in BMK regions
Also only B, M, K primary colours participate in colour mixture, i.e., in the color models of CMYKOB six, only 5 areas, any color point P in each subregion
Constituted by the adjacent primary colours of two form and aspect in the CMYOB five colors plus K colors, the boundary color in Liang Ge areas is exactly one
Primary colours add K colors, that is to say, that at most only need to be expressed with three kinds of colors, as shown in Figure 3.It is mixed in each subregion after subregion
Color, which is constituted, only constitutes the most three kinds of colors of two kinds of primary colours plus K colors of the subregion, and stamping ink water is no more than 300%, and not with
The increase of printing primary colours ink channel and increase, the overlapping probability of ink dot can be substantially reduced, be expected to increase the accuracy of color
And stability；The black consumption increases of K after other subregion colour mixture, are expected to make neutral gray scale stable, improve grey balance effect；Adopt simultaneously
Total ink amount can be substantially reduced with the partition model, the printing cost of digit printing is reduced.
By taking the CBMK regions of the colors of CMYKOB six as an example, as shown in figure 4, the CKMx areas in the multiple bases colour mixture model of standard
It is theoretically by this six kinds of primary colours colour mixtures of C, M, Y, K, O, B, but the royalblue actually in this region of CKMx in domain
The ratio that B participates in colour mixture is low-down, only just has royalblue B to participate in colour mixture, therefore royalblue B inks in CBMx regions
Usage amount it is not high.And be that colour mixture is carried out according to region difference in the colour mixture model set up based on subregion, CBMK is divided into
Two different regions of MBK and CBK, any point color in MBK regions is M, B, K these three primary colours composition, in CBK areas
Domain is tri- kinds of primary colours compositions of C, B, K, and the boundary color in MBK and CBK Liang Ge areas only adds K colors with single royalblue B,
Royalblue B usage ratio is greatly increased in whole CBMK regions, so more meets the original intention of multiple bases (multichannel) printer.
In addition, minimum based on the ink channel that colour mixture is participated in subregion multiple bases colour mixture color model, color is not easy sideslip, therefore
All can be advantageous in terms of bright-colored degree, muted color grey balance, increase spot color inks usage amount.
The present invention illustrates the ICC characteristic file preparation methods to the color colour mixture model generation based on subregion.
Based on subregion multiple bases color（Colour mixture）The ICC Profile generation methods of model：
The first step：By the colour mixture principle of multiple bases color model of the present invention based on subregion, the ICC Profile of printer are generated
The color table of characteristic file.Each sample value is uniformly distributed in printer color space as far as possible in color table, and can true reappearance
Printer colour gamut.In order to which the ICC Profile generations for meeting standard ICC color management require that sample is divided into 2 portions in color table
Point：
（1）Main part：
Subregion distribution generation color table sample is pressed, all samples are former fully according to the colour mixture of the multiple bases color model based on subregion
Reason, i.e., the combination for adding K inks according to 2 primary colours inks is generated.
Fig. 5 is CMYKOB six-basic-color spatial distributions, it can be seen that whole space is divided into five sub-regions, is respectively
MBK, BCK, CYK, OYK, MOK, form sample basic framework.Any color lump concentrated for color card, by calculating color
Hue angle can determine the subregion where the color, fall each color in subregion and can use two primary colours of the subregion to add
Upper black is replicated.In this color model, the weight of two Essential colour determines the form and aspect of color, and the ratio of black is then
The brightness of color can be adjusted.
Color lump in sample is generated according to different zones, there was only C, B, K color composition in CBK regions, in BMK areas
Domain also only has B, M, K ink to participate in colour mixture, i.e., the color of the sample color lump of each subregion only has two kinds of adjacent primary colours to add
Black.
The BtoA that main part is used in ICC Profile（Conversion of the standard PCS to device color spaces）Life
Into, and AtoB tables (conversion of the device color spaces to standard PCS) part.
For example tag file connection space uses CIE Lab, any CIE Lab chromatic values（Only take multiple bases color model
In two primary colours blacken color）Mutually it is mapped with the colour mixture data for blackening color according to above-mentioned two primary colours in device color spaces.
（2）Redundancy section：
In main part color table sample, BtoA in ICC Profile disclosure satisfy that（Standard PCS arrives device color spaces
Conversion）The formation condition of table.But because the colour mixture model based on subregion, in each subregion, only use constitute the subregion 2 kinds
Ink adds K inks, and the ink of other subregions does not participate in colour mixture, therefore in whole equipment color space to PCS spaces
In conversion, each Color Channel of device color spaces is not circulated completely, it is impossible to meet generation AtoB tables in ICC specifications
The condition of (conversion of the device color spaces to standard PCS).So needing to increase some equipment redundancy data circulated completely, come
Meet AtoB establishment condition.
The complete loop-around data of the redundancy refer in N color color model except the adjacent primary colours of two form and aspect and black with
Outer chromatic value combination, it is only for meet the establishment requirement of ICC Profile AtoB tables.For based on subregion colour mixture mould
The practical application of type, in print procedure, only uses BtoA tables., it is necessary to use AtoB table transforms in Soft proofing and display are used
When, by BtoA table transforms to the ink channel in printer space combine and belong to main part data, therefore redundancy section number
According to seldom encountering, the circulation value of redundancy is 0:50:100%.
2nd step：According to ICC color management specifications, color table is printed, and measurement.This step is standard method.
Obtain meeting the printer colorspace data based on subregion multiple bases color model colour mixture principle（2 primary colours inks
Plus K ink）With Standard Colors data（ICC PCS, such as CIE Lab）Corresponding relation.
3rd step, creates ICC Profile, comprises the following steps：
Creation method：
BtoA ：The main part data creation that sample is generated based on subregion is fully utilized；
AtoB ：In addition to using the main part data generated based on subregion, constituted along with the complete loop-around data of redundancy
The color data of tag file connection space.Specific steps are setting up the face based on subregion referring to Fig. 7, the innovative point of the present embodiment
Colo(u)r atlas color table step, remaining is prior art.
Compared with existing ICC Profile preparation methods, the present invention has advantages below：
The present invention creates multichannel color colour mixture model, to ink based on multichannel ICC Profile by partitioned mode
Channel sample is combined, it is assumed that port number is N, and the sampled point quantity of each passage is G, two kinds of adjacent primary colours (N-1 of selection form and aspect
Group) closed with black ink K colour cells, the structure of property samples collection is individually carried out to each subregion, the sample per sub-regions is limited
At most it is made up of three kinds of inks, such total sample number has been reduced to G3× (N-1), sets up property samples collection and prints, measurement
The corresponding CIE Lab chromatic values of sample set are obtained, are then set up by mathematical method between sample set chromatic value and input signal
Mathematical modeling, comply fully with ICC codes and standards.
For multichannel printer, on the basis of (blue or green, product, Huang is black) of traditional 4 color, by expanding primary colours number
Amount carrys out the gamut range of expanded view picture, makes printing color more gorgeous, improves the degree of accuracy of Color Replication, and colour gamut subregion not only drops
Low color space dimension, and eliminate color redundancy, sample set sum is also greatly lowered, and alleviates printing and measurement
Workload.
Simple deformation or the combination of every present techniques feature and technical scheme, it is considered that fall into the protection of the application
Scope.
