Embodiment
Below, the several preferred embodiment of the present invention is enumerated and to coordinate accompanying drawing to be described in further detail as follows:
First, the method of a preferred embodiment of the present invention coloring matter comparison, its first step irradiates the tested sample of a coloring matter with specific light, and measure the reflectance value of this coloring matter different wave length in default wave band, to obtain reflectance spectrum: this specific light can be the light that Halogen lamp LED is launched, and utilize the tested sample coloring matter of a spectrometer measurement at the reflectance spectrum of different-waveband (as 350nm to 1000nm), as shown in Figure 2, this coloring matter is carmetta (magenta) ink of printer, and its tested sample is as the R in Fig. 2
aline.
Second step of the present invention chooses the reflectance spectrum of the coloring matter master sample of a predetermined color and concentration: select and that concentration different coloring matter master sample identical from this tested sample component, measure the reflectance spectrum of this coloring matter master sample, this coloring matter master sample is as the R in Fig. 2
bline.
Third step of the present invention is according to the comparison of following comparison formula this tested sample and master sample:
Wherein, R'
afor the reflectance value calculated, R
bfor the reflectance value of this coloring matter master sample, n is concentration ratio, C
1, C
2for correction factor.
Aforementioned comparison formula is that the reflectance formula correction of foundation Lambert-Beer's law comes, according to aforementioned correction formula R '
a=(R
b× C
2)
nthe reflectance value of each master sample is multiplied by correction factor C
2after union, reflectance value shown in dotted lines in Figure 2 can be obtained, wherein, C
2=1.15, n=0.63.As shown in Figure 2, will only cannot coincide by surplus next section in reflectance spectrum, i.e. 450nm ~ 600nm.
Final step of the present invention judges whether the tested sample of this coloring matter and master sample are homochromy: as shown in Figure 2, the dotted line obtained by aforementioned correction formula computing, it is at wave band 600 ~ 950nm and grey filled lines (R
aline) comparison coincide, therefore, the tested sample of this coloring matter known and master sample are homochromy.
Base this, the method for this coloring matter comparison of the present invention, by abovementioned steps, it not only can judge whether the tested sample of coloring matter and master sample are homochromy, the problem that the wave band that when more can improve comparison, reflectivity is higher cannot coincide.
Secondly, the present invention more provides the method for another preferred embodiment coloring matter comparison, required correction cannot be covered completely mainly for coloring matter, also be, when pigment application is in object surface, often can see in color having the white part of object surface (the dot matrix colouring particularly industry printing adopted), for avoiding the reflectivity counting white during reflective spectral measure, the reflectivity of white must be deducted after measurement, its step is identical with previous embodiment substantially, difference be in: it is according to following correction formula comparison this tested sample and master sample:
Reflectivity is deducted correction factor C by this correction formula
1after launch to scale, then coordinate the correction formula of previous embodiment rewrite form, wherein, R'
afor the reflectance value calculated, R
bfor the reflectance value of this master sample, n is concentration ratio, C
1for the covering correction factor of this coloring matter coating, C
2for the top layer correction factor of this coloring matter coating.
By this, to compare correction, can obtain the reflectivity comparison data fitted like a glove after recalculating according to aforementioned correction formula, namely variable concentrations spectrum can complete comparison under albedo measurement, as shown in Figure 3, wherein, and C
1=0.0285, C
2=1.148, n=0.595.
Base this, even if coloring matter does not cover object surface (pigment application is uneven) completely, by above-mentioned correction formula, the interference that spectral measurement time error causes can be removed completely, the reflectance spectrum that the acquisition tested sample of coloring matter and master sample fit like a glove, whether the spectrum degree that coincides is high, can identification coloring matter be identical component exactly, and more adequately can be applied to the judgement of concentration.
Secondly, inventor more utilizes the experiment of following measurement multiple concentration coloring matter reflectance spectrum, and proved invention is applicable to the coloring matter comparison of variable concentrations, as shown in Figures 4 and 5:
First, utilize laser printer on white A4 paper, print off cyan (Cyan) primary colors of variable concentrations (25%, 50%, 75%, 100%, 200% and 300%), this experiment is with the benchmark (dark solid) of C300 (concentration 300%) as comparison, utilize this benchmark spectrum to carry out computing (dotted line) and carry out other concentration optical spectrums of comparison, first use known Lambert-Beer's law to carry out luminance factor pair, the person of connecing re-uses aforementioned correction formula and compares:
And in order to know difference mainly in which part after comparison, more former spectrum and spectrum to be subtracted each other, the foundation which wave band is the data (x line) of gained just can misfit at as spectrum.As shown in Figure 4, use known Lambert-Beer's law to carry out concentration ratio pair, can find that reflectance spectrum cannot coincide, wherein cover with pigment the impact not exclusively producing white part again the most obvious.And as shown in Figure 5, use correction comparison formula to carry out concentration ratio pair, can find that all concentration all can be coincide in comparison, the mean difference of comparison is less than 0.8%, the spectroscopic data closely measured.
Accordingly, method of the present invention is applicable to the coloring matter comparison of variable concentrations really, and comparison result is all identical.
In addition, as shown in Figure 6, the present invention more provides a kind of system 10 implementing aforementioned coloring matter comparison method, includes lamp source 12, spectrometer 14 and an operating unit 16.This lamp source 12 is Halogen lamp LED, (by an optical fiber 22) the tested sample of coloring matter and master sample 1 is irradiated in order to light can be produced, this spectrometer 14 is known spectra instrument, the reflection ray of the tested sample of coloring matter and master sample 1 is received by another optical fiber 24, this operating unit 16 is the computer equipment connecting this spectrometer 14, the spectrogram of the tested sample of color substance and master sample 1 can be had, include a computing module 26, for the operational software of built-in Lambert-Beer's law reflectivity correction formula, the computing of reflectance value can be carried out according to the comparison formula described in previous embodiment, in order to judge whether the coloring matter of this tested sample and master sample 1 is homochromy.
As from the foregoing, the method and system of this coloring matter comparison of the present invention, it is by the measurement of pigment spectrum, and to be compared computing by the Lambert-Beer's law revised, the error that the factor such as can remove gloss reflection completely and pigment application is uneven causes, the reflectance spectrum comparison of identical coloring matter can accurately be coincide, and then the detection of multiple coloring matter or medicine mixing, the classification of coloring matter data bank and automatic comparison can be applied to, more can be used for the judgement of concentration, very have practical value.
Moreover when the non-pure white of the object that pigment is coated with (paper or painting canvas) its substrate, its comparison formula can be modified to:
