摘要： PURPOSE:To provide a paint color matching method that can rapidly obtain precise mixture. CONSTITUTION:In this paint color matching method, the predictive result obtained by computing the paint film color of a mixed paint, obtained by mixing plural raw material paints, on the basis of basic data every raw material paint is compared to the colorimetric result of a color sample, and raw material paint mixture with the difference between both results being within a specified range is obtained. At this time, the predictive result is computed by a two- constant method, and when the difference between the colorimetric result and predictive result is not within the specified range, a single constant method is applied, or in a color matching method to a color sample with high saturation, the predictive result is computed by a single constant method.

摘要： PURPOSE:To accurately make color of a colored resin product coincide with that of a color sample, by incorporating an influence of a filler as a correction factor in a computer color matching method to carry out color matching. CONSTITUTION:In carrying out color matching by calculating a coloring formula of a resin product containing a filler is calculated using a computer color matching method, an influence of the filler on coloring as a correction factor is incorporated in the calculation process to perform color matching. The amount of the filler is calculated by using fundamental data of each pigment determined from mass tone prepared by using a resin without containing a filler and letdown color sample and filler data obtained from the resin containing the filler and color sample prepared by blending the resin with a white pigment (titanium oxide) or black pigment (carbon black).

摘要： PURPOSE:To obtain a method for predicting result of color mixing through which even an unskilled person can select an appropriate object of calculation, i.e., a coloring agent, and which can realize computor color matching in which fluctuation due to individual difference is suppressed. CONSTITUTION:In the method for predicting the result of color mixing, a color is sectioned into a plurality of color sections R...P according to the hue and the chroma and a group of coloring agents suitable for the color tones in respective color sections is set for respective color sections. A decision is then made with which color section the color of color sample corresponds and the color section corresponding with the color of the color sample is selected. Result of color mixing is operated through computor processing when an object is colored with a coloring agent belonging to a coloring agent group corresponding with thus selected color section.

摘要： PROBLEM TO BE SOLVED: To be able to express colors more similar to real colored articles as a color sample composed of colored images made by CG technology, and to realize an accurate and quick toning operation.
SOLUTION: The color sample to evaluate an expression color in a coloring status of an object article to be colored by a coloring agent is comprised of a color sample image 30 displayed by an image display device. The color sample image 30 is obtained by combining shape characteristic information relating to a surface shape of the object article and color characteristic information of the coloring agent. Coloring with the color characteristic information is performed to the surface with the shape characteristic information. In this manner, the colored image of an virtual object is obtained.

摘要： PROBLEM TO BE SOLVED: To reduce work quantity required for calculation and to realize rapid prediction by calculating a K/S parameter of a mixed coloring material from a K/S parameter measured of each basic coloring material by a specific expression. SOLUTION: A plurality of liquid samples are prepared, which include every the same amount of non-coloring materials which indicate a bigger scattering coefficient than that of a basic coloring material and include a stepwisely different amount of the basic coloring material. With respect to every liquid samples, a spectral reflectance is measured and a K/S parameter of the respective basic coloring materials is calculated from the spectral reflectance measured. At this time, in the spectral reflectance of the liquid samples, the influence of scattering is controlled by the non-coloring material containing the same amount. Even if the amount of the basic coloring material is different, the influence to scattering can be ignored and an absorption coefficient may be only considered as a parameter influencing to the difference of the color. Accordingly, the K/S parameter (K/S)m of the mixed coloring material can be simply calculated from the K/S parameter (K/S)i and the mixed amount Ci by an expression. Thereby, work quantity required for calculation can be reduced and the K/S parameter of the mixed coloring material can be rapidly predicted.

摘要： PURPOSE:To carry out proper color matching easily by finding an actual color value of a color reference and a predictive color value for a material to be colored after correcting spectral reflectance. CONSTITUTION:When a combination of plural coloring agents, which are used for coloring a material to be colored the same color as the color of a color reference, is computed by a computer process, an actual color value of the color reference is found on the basis of a spectral reflectance R of the color reference, and on the other hand, a predictive color value is found on the basis of a predictive spectral reflectance (r). In these both computing processes, a corrected spectral reflectance Ralpha, which is found by adding a difference (a-b) between a spectral reflectance (a) containing a mirror face reflected light in a single coloring sample used for obtaining respective data of coloring agents and a spectral reflectance (b) containing no mirror face reflected light to a spectral reflectance B containing no mirror face reflected light in the color reference, in other words, which is indicated by a formula Ralpha=B+(a-b), is used for a reflectance R, and an actual color value of the color reference is found.

摘要： PURPOSE:To perform color matching quickly and sufficiently accurately by using the data of the composition of resin to be colored which is obtained from the spectral reflectance from a sample for measuring the composition data of the resin to be colored together with coloring agent data, and computing the result of color mixing. CONSTITUTION:A resin sample A is independently colored with each coloring agent among a plurality of coloring agents. A resin sample B is colored by using both a coloring agent and an achromatic color agent. A coloring-agent-data measuring sample comprises the sample A and the sample B. The coloring agent data obtained from the spectral reflectance from the coloring-agent-data measuring sample are used as a basis and processed in a computer. In addition, a resin composition sample C is prepared only with the composition of the resin to be colored as the sample for measuring the composition data of the resin to be colored. A resin composition sample D is prepared with the composition of the resin to be colored which is colored with only the achromatic color agent. The composition data of the resin to be colored obtained from the spectral reflectance from the sample for measuring the composition data of the resin to be colored are used together with the coloring agent data, and the result of the color mixing is computed. In this way, man-hours for preparing the sample can be saved because it is sufficient that only a few items of the composition data of the resin to be colored need be measured and the prototypes are manufactured.
