At this, above-mentioned colorant fit rate calculating apparatus 100 is provided with CPU (central operation device) (not shown), by by realizing above-mentioned aim colour particular value calculating section 121, hue-angle range computing calculating section 122, CCM calculating part 123, coordinate result look particular value calculating section 124, hue-angle range computing judging part 125, aberration calculating section 126 and centre-of-gravity range judging part 128 each function program (not shown) thus be loaded into and on memory 110, carry out realization.
In addition, above-mentioned each function also can realize with specialized hardware.
Then, with reference to the accompanying drawings of obtaining the substrate information of design object from designer and becoming the color card of aim colour, according to these, decide the action of best colorant fit rate.At this, establish by designer and posted the color card that passes through the color that light source can not reproduce with colorant due to the difference of the substrate of specified substrate and color card.In addition, in determining the processing of colorant fit rate, utilize three kinds of standard sourcess.
Fig. 3 means that colorant fit rate calculating apparatus 100 calculates the flow chart of the action of colorant fit rate.First, select the color of expectation the color card that designer has from designer self, this color card is posted by Bing Xiang ink manufacturing company, and notice is made as the information of the substrate of design object.In addition, designer also can not select color from color card, and carrys out intended target look with method for distinguishing.The director of ink manufacturing company, when receiving color card, measures its spectral reflectance and inputs from the input part 150 of colorant fit rate calculating apparatus 100, is saved in color card spectral reflectance DB 113.The substrate information of then, input notice.
The CCM calculating part 123 of colorant fit rate calculating apparatus 100, when accepting substrate information (step S1) from input part 150, is saved in memory 110 temporarily.Afterwards, aim colour particular value calculating section 121, according to the isochrome function of three kinds of minutes light emission intensity of the spectral reflectance of the aim colour in aim colour spectral reflectance DB 113, minute light emission intensity DB 114 and isochrome function DB 115, is calculated the L of three kinds of aim colours by each light source *, a *, b *value (step S3).
Fig. 4 projects to certain L by the aim colour under three kinds of light sources *the a of value *b *figure in plane.As shown in the drawing, by a *b *the position 401,402,403 of departing from plane represents to project to above-mentioned a *b *aim colour under three kinds of light sources in plane.Hue-angle range computing calculating section 122 is calculated respectively and is projected to a *b *three kinds of formed hue angles of aim colour in plane, calculate the scope of their residing hue angles.In the figure, project to a *b *among three aim colours in plane, certain aim colour (this figure 402) forms θ 1hue angle, a side of other aim colour (this figure 401) forms θ 2, all the aim colour under light source forms hue angle and makes to enter θ 1and θ 2between scope in.Hue-angle range computing calculating section 122 is by θ 1～θ 2value range be saved in (step S4) in memory 110.
Then, colorant fit rate calculating apparatus 100 calls substrate information from memory 110, can be at a of colorant from corresponding with this substrate *b *in the chroma scope of reproducing in plane, select the colorant using in coordinating.At this, as shown in Figure 4, as a under the principal light source in a plurality of light sources or specified light source *b *coordinate, the roughly known chroma scope being represented by colorant.In Fig. 4, show as an example as each colorant at the color particular value of the highest chroma point of each light source (411 in figure, 412 etc.), can utilize CCM calculating part 123 and the cooperation result color particular value calculating section 124 of according to mutual colorant combination and mixing ratio, calculating reflectivity to obtain each the highest chroma point, with curve, be connected their line.At this, the identical point of figure (quadrangle, triangle, circle) being configured on the coordinate plane of Fig. 4 represents it is the color particular value under same light source.
In addition, this illustrates following state: aim colour 403 is at least positioned at the inner side of the line that connects them under the light source of having calculated two color particular values 421,422, can carry out the performance of chroma.On the other hand, mean having calculated under the light source of 431 and 432,411 and 412 color particular value, with the colorant of aluminium substrate, can not reproduce aim colour 401,402.
Preferably by selection, project to a *b *the a of the aim colour in plane *b *coordinate and at a *b *in plane, be distributed in the shortest locational colorant of distance, carry out the decision (step S5) of colorant.The information relevant with the colorant of selecting is stored in memory 110.Now, for example projecting to as shown in Figure 4 a *b *in the high situation of the chroma of the aim colour in plane, detect two kinds of colorants 411,412.On the other hand, in the situation that chroma is low, select more than three kinds colorants.
Then, the colorant information that detects and preserve in the substrate information that CCM calculating part 123 is inputted from memory 110 reading step S1 and step S5, reads and this substrate, spectral reflectance that colorant is corresponding with DB112 from Color matching.For example, in the situation that substrate information represents that aluminium, colorant information represent colorant A and colorant B, first read aluminium substrate, colorant A in Fig. 2 and be 100%, colorant B is the spectral reflectance under 0% fit rate.Then, carry out spectral reflectance and the allotment of aim colour.Then, then be kept at that Color matching carries out again with the fit rate in DB 112 and the spectral reflectance of aim colour between allotment, whole fit rate of preservation are repeated.Afterwards, aim colour as shown in Figure 5 and colorant coordinate the spectral reflectance of result such, and the fit rate of the colorant by allotment the most successfully, while being minimum with the difference of the spectral reflectance of aim colour is saved in (step S6) in memory 110.At this, the longitudinal axis is spectral reflectance [%], and transverse axis is wavelength [nm].The 501st, the spectral reflectance curve of aim colour, the 502nd, coordinated the spectral reflectance curve of the result of colorant A in aluminium substrate and colorant B.The 511st, the spectral reflectance curve of aluminium itself does not have the color over this curve in the situation that of aluminium substrate in principle, from this figure yet known aim colour, is therefore not reproducible color.In addition the part that also can calculate the decision of colorant as CCM, is carried out.
Then, coordinate result color particular value calculating section 124 to read fit rate from memory 110, from Color matching, with DB 112, read corresponding spectral reflectance, with reference to itself and three kinds of minute light emission intensity of minute light emission intensity DB 114 and the isochrome function of isochrome function DB115, the L that calculates the colorant cooperation result in 3 light sources *, a *, b *value (step S7).
Afterwards, hue-angle range computing judging part 125 is read the range Theta of hue angle from memory 110 1～θ 2.Then, calculate respectively and coordinate the color of result to project to a in the colorant in 3 light sources *b *a in the time of in plane *, b *be worth formed hue angle, judge whether it is all projecting to a *b *the range Theta of the formed hue angle of aim colour in plane 1～θ 2interior (step S8).The result of judgement, when in the range Theta of hue angle 1～θ 2in situation under, the fit rate (step S9) that the fit rate of use is changed to its periphery afterwards, is transferred to step S7 and is repeated to process.
In addition, can carry out the judgement of repetition hue-angle range computing by the ratio that changes each colorant with fixed proportion successively, thereby carry out the change of the fit rate in step S9.In addition, director can also input the change of fit rate.And, undertaker can also carry out colorant change, append.
On the other hand, the result of judgement, when the range Theta at hue angle 1～θ 2in interior situation, each light source of aberration calculating section 126 and three kind of light source is calculated accordingly and is projected to a *b *the a of the aim colour in plane *, b *value and project to a *b *colorant in plane coordinates a of result *, b *poor (step S 10) of value.At this, will project to a *b *the a of the aim colour in plane *b *coordinate is made as (At, Bt), by a of the color of the cooperation result under same light source *b *the calculating formula of the aberration (a, b) when coordinate is made as (Am, Bm) is a=Am-At, b=Bm-Bt.According to this formula, by each light source of three kinds of light sources, calculate respectively a of aberration *, b *value.This computing is equivalent to a of the cooperation result under mobile same light source *b *coordinate makes a that projects under certain light source *b *the a of the aim colour in plane *b *coordinate becomes initial point.
Centre-of-gravity range judging part 128 is presented at the input requirements of the value of the scope of using in the judgement of position of centre of gravity on efferent 160.When taking on that people sees it and during from input part 150 input value, the centre-of-gravity range judging part 128 of colorant fit rate calculating apparatus 100 of having accepted it is that calculate according to aberration calculating section 126, project to a *b *aim colour under 3 light sources in plane and coordinate the aberration of result, judges that their formed leg-of-mutton barycentric coodinates are whether within the scope of the value of input (step S11).In addition, also can preset the scope that the judgement of position of centre of gravity is used.Illustrate below and will project to a *b *the a of aberration in plane, in 3 light sources *b *coordinate is made as (a 1, b 1), (a 2, b 2), (a 3, b 3), by a *be made as-α of axial scope～+ α, by b *the judgement formula of barycentric coodinates during be made as-β of axial scope～+ β.
[formula 1]

Like this, calculate and project to a *b *a in plane, that comprise the aim colour in 3 light sources respectively *, b *the scope of hue angle of value, judges a of the result that a plurality of colorants coordinate *b *whether coordinate is in the scope of hue angle, the in the situation that of in scope, the fit rate that shows corresponding colorant, therefore can calculate effectively by due to light source kind, not reproducible aim colour is reproduced as no less than the colorant fit rate of the Color matching result degree of being undertaken by people.
In addition, by L *a *b *l in color specification system *value is made as constant, at a *b *in plane, obtain the fit rate of colorant, therefore generally only consider the chroma that importance degree is high, thereby can alleviate the load of calculating processing of colorant fit rate.
In addition, in the above-described embodiment, used the center of gravity for three kinds of light sources, but can be also more than two kinds or three kinds.The in the situation that of two kinds of light sources, calculate a *b *the mid point of two aberration in plane.Thus, with respect to the situation of three kinds of light sources, can alleviate the load of processing.In addition, more than three kinds light source in the situation that, calculate about at a *b *the center of gravity of the figure using each aberration as summit in plane.Thus, can under the light source of a plurality of kinds, evaluate colorant and coordinate result, can obtain the colorant fit rate of versatility.
In addition, in the above-described embodiment, illustrated at L *a *b *in color specification system at a *b *the worthwhile situation that goes out the fit rate of colorant of plane, but also can consider respectively L *, a *, b *, similarly utilize scope, center or the center of gravity of hue angle, calculate the fit rate of colorant.In addition process, the difference of the processing that is only 2 peacekeeping 3 dimensions.
In addition, in the above-described embodiment, scope when judgement of barycentric coodinates also can be on specific direction of principal axis additional coefficient.Thus, can access the result that the direction of principal axis of designer's attention has been carried out to weighting.Specifically, by being multiplied by coefficient in the mid point obtaining or center of gravity or being multiplied by coefficient in the value of the scope shown in presentation graphs 6, undertaken.

The colorant that the embodiment of the present invention is described is with reference to the accompanying drawings selected servicing unit.Fig. 9 means the block diagram of the structure of the colorant selection servicing unit in present embodiment.In Fig. 9, to the part mark prosign identical with the device shown in Fig. 1, the description thereof will be omitted.The point different from the colorant fit rate calculating apparatus shown in Fig. 1 be point that the structure of the colorant control part 220 of selecting servicing unit 200 is different, the different point of the structure of DB 112 ' Color matching for, be also provided with the point that colour gamut is calculated use DB 116.The following describes the point different from the device of Fig. 1.In addition, in colorant is selected servicing unit 200, directly or by network etc. be connected with not shown display unit, control part 220 outputs to this display unit by the result of processing etc.
Control part 220 possesses colorant display part 221, aim colour display part 222, colorant selection portion 223, selects colorant display part 224, CCM calculating part (colorant fit rate calculating section) 225, CCM result display part 226.
Colorant display part 221 is calculated the coordinate position of the colorant in appointed substrate in the three-dimensional color space of regulation.Now, colorant display part 221 is handled as follows: use and be stored in the colorant reflectivity information of the colorant in DB 112 ' for Color matching, a plurality of concentration to this colorant are obtained the coordinate position in this solid space, and the variation using the change in concentration of this colorant as coordinate position on this three-dimensional color space shows.Each colorant of 221 pairs of registrations of colorant display part carries out above-mentioned processing.In addition, solid space is to represent above with 3 dimensions the color space of color position, for example, be XYZ color specification system, L *a *b *color specification system, L *u *v *color specification system etc.In the present embodiment, the L of the image that approaches the Color matching that becomes this device user will be can be described as *u *v *color specification system describes as the example in three-dimensional color space.
Aim colour display part 222 is handled as follows: use the aim colour reflectivity information being stored in aim colour spectral reflectance DB 113 to calculate L *u *v *the coordinate position of the aim colour in color specification system, the coordinate position of the aim colour that demonstration is calculated.Colorant selection portion 223 enters following processing: impel the user of device to select the more than one colorant coordinating, obtain for determining the colorant information of the colorant of being selected by not shown input unit by user, and store in memory 110.Select colorant display part 224 to carry out can reproducing the Graphics Processing etc. of the colour gamut of selected colorant in the substrate of appointment.CCM calculating part 225 is used the colorant spectral reflectance information of the colorant of selecting and aim colour spectral reflectance information etc. to calculate the fit rate of the selected colorant in the substrate of appointment.The fit rate information of the colorant that CCM result display part 226 use are calculated by CCM calculating part 225 shows the processing of result.
At this, above-mentioned colorant selects servicing unit 200 that CPU (central operation device) (not shown) is installed, by the program (not shown) that realizes each function of above-mentioned colorant display part 221, aim colour display part 222, colorant selection portion 223, selection colorant display part 224, CCM calculating part 225, CCM result display part 226 is loaded in memory 110 and carries out and realize.In addition, also can realize above-mentioned each function with specialized hardware.
Then, DB 112 ' for Color matching is described.Figure 10 means and is stored in the figure of an example of the colorant spectral reflectance information in DB 112 ' for Color matching.As shown in the figure, Color matching is stored the spectral reflectance information 304 of each colorant 302 with DB 112 '.And, about the spectral reflectance in a plurality of dilutions 303, store each colorant.At this, dilution be to coloring material for mixing the fit rate of the diluent for colorant during diluent.Thereby dilution is that the situation of zero " 0 " represents the situation that extended color is not used.In addition, when substrate is different, the spectral reflectance of material of all kinds changes.Therefore, by each substrate 301, preserved respectively the spectral reflectance of each colorant.In addition, the dilution of colorant for example possesses the spectral reflectance of 95,90,80,70,50,40,20,0 situation.In addition,, although do not illustrate, also can apply the further spectral reflectance that increases each colorant while thickening by the China ink when printing in Figure 10.
Illustrate that colour gamut calculates with DB 116.Figure 11, Figure 19 mean that colour gamut calculates the figure by the structure example of DB116.When selecting colorant display part 224 to carry out the relevant processing of colour gamut with selected colorant, with reference to colour gamut, calculate with DB 116.In order to show in the substrate of the colorant appointment of selecting reproducible colour gamut outer rim and the boost line that shows colour gamut in the colour gamut inside can enough two colorants showing, utilize the colour gamut shown in Figure 11 to calculate with DB 116.Colour gamut shown in Figure 11 is calculated the mixing condition 312 that represents the fit rate of two colorants (colored 1, colored 2) and diluent with DB 116 storages.In Figure 11, as the concentration 311 of two colorants, show the example in 4 stages of 100%, 50%, 25%, 12.5%.For example, the fit rate of 50% pair of two colorant of concentration is carried out a plurality of stage settings, and the fit rate sum that to make the ratio of the diluent of colorant be 50%, two colorant becomes 50%.In the example of Figure 11, the cooperation stage of two colorants is made as to 5 stages.In addition, as can be seen from Figure 11, the fit rate of two colorants also comprises the situation that do not comprise a colorant, the fit rate of a colorant is zero situation.
In the situation that the colorant of selecting is more than 3 looks, in the colour gamut foot for the colour gamut outer rim inner side in becoming specified substrate, show the boost line of colour gamut, with reference to the colour gamut shown in Figure 19, calculate with DB 116.At this, the fit rate mixing condition 321 of each colorant while being set with the colorant of having selected 3 looks.In this colour gamut, calculate with in DB 116, the fit rate sum of setting 3 looks for is 100%.About the mixing condition setting, separately explain.
Use Figure 12 that the action of colorant selection servicing unit 200 is described.First, colorant selects servicing unit 200 to accept the spectral reflectance information of color card, to reproducing the substrate of the color of this color card, carry out the input of definite information.Control part 220 stores the spectral reflectance information of the color card of input in aim colour spectral reflectance DB113 into, and stores the information of determining substrate in memory 110 (step S21).In addition, this color card becomes the aim colour showing with more than one colorant for the substrate in appointment.
Colorant display part 221 is with reference to DB 112 ', light splitting reflected intensity DB114 for Color matching, calculates L in each dilution of each colorant in the substrate of appointment, under regulation light source *u *v *the coordinate position of color specification system.Colorant display part 221 carries out following processing: utilize the coordinate position of calculating, the variation (step S22) of coordinate position when coordinate position, colorant when demonstration colorant is diluted from 0% to 100% produces change in concentration by dilution.At this, the change list of the coordinate position while carrying out colorant to produce change in concentration is shown in L *u *v *the plane of every 2 axles in color specification system, be u *v *plane, L *u *plane, L *v *graphics Processing in these 3 planes of plane.
Figure 13 is the flow chart that illustrates in greater detail the processing of colorant display part 221.First, colorant display part 221 is calculated the L of the colorant (i, j) in the colorant of appointment *u *v *coordinate position in color specification system (step S22a).At this, " i " represents the kind (numbering) of colorant, and " j " represents the dilution stage (concentration stage) of this colorant.At this, be located at Color matching with being registered with m kind colorant in DB 112 ', as dilution stage, registered the p stage.In addition L, *u *v *the coordinate position of color specification system is calculated and can be obtained by following processing: according to the light splitting reflected intensity of the concentration of the spectral reflectance of the colorant in the substrate of appointment, colorant, regulation light source, calculate the coordinate position in XYZ color specification system, utilize isochrome function from the coordinate position of XYZ color specification system, to be transformed to L with DB 115 *u *v *the coordinate position of color specification system.In addition, this processing is the calculation method of color specification system coordinate position known in this field, omits detailed explanation.Thus, obtain colorant (i, j) { i:0 <=i < m; The L of j:0 <=j < p} *u *v *the coordinate position of color specification system.In addition, the light source of regulation being made as to inhomogeneous few standard sources is below D65.
Then, colorant display part 221 is handled as follows: the u that uses the coordinate position of obtaining *value, v *value, the variation of coordinate position when colorant has been produced to change in concentration is presented at u *v *in plane (step S22b).Figure 15 (a) is at u *v *the display case of the variation of the coordinate position while having produced respectively change in concentration is shown about 8 colorants in plane.In (a) of Figure 15, from " A " to " H " represents colorant name.Like this, be preferably in while showing and also add that colorant name shows.In addition, about the change in concentration of each colorant, both can describe simply m stage concentration, also can describe in addition to make to supplement the concentration in m stage.And, during demonstration, as long as change color by each colorant, describe.
221 couples of L of colorant display part *u *plane, L *v *plane is also carried out the processing identical with step S22b (step S22c, S22d).(b) of Figure 15, (c) are respectively at L *u *plane, L *v *the display case of the variation of the coordinate position while having produced respectively change in concentration is shown about 8 colorants in plane.
