Problems solved by technology
[0002] At present, the color matching of ordinary dyes must be done by an experienced colorist. However, the human eye increases with age, which makes the vision tend to age, and it is easy to distinguish similar colors. During manual color matching, the proportion of the color samples of the three primary colors depends on the color matching master, which often causes errors when different people match the same color; when using software to simulate color matching, it is often impossible to display the closest color samples for color matching that cannot be matched The color sample area makes it impossible to complete the color matching, and for the color samples that can be matched, it is impossible to make various observations and display the color area where it is located, which needs to be improved

Embodiment Construction
[0028] as attached figure 2 As shown, select red, yellow, and blue dyes, dye red O1, dye yellow O2, and dye blue O3. To analyze whether the target color sample P1 can be completely matched, when it is displayed, check the parameters of the function selection switch area L , including frame L1, dye L2, target color L3 and boundary color L4 to change the display state, and change the parameters of the coordinate area M, including L * Shaft adjustment M1, a * Axis adjustment M2 with b * The function of axis adjustment M3 is to change the rotation angle of the displayed coordinate axis, and to adjust the size of the color ball N1 and the size of the view N2 to change the displayed size distance and the size of the target color ball P1 to be smaller than that in the figure;
[0029] Since the function of the boundary color L4 is not checked, only the main color curves Q1, Q2, Q3 and the target color sample ball P1 to be analyzed are displayed. In the figure, CIE L * a * b * T...

The invention provides a three dimensional image judge method of color compounding of dyestuffs. It belongs to chemical industry field. Its steps include start, color measure, CIE Lab value computation, color sample display in three dimensional coordinate, canceling display flag of the sample, CIE coordinate zoom, recalculating CIE Lab value, the color sample zoom, recalculating sphere size of color sample, color axis of CIE Lab rotation, each axis of CIE Lab recalculation, display in screen and information process and end. Merits of the invention are that veracity of colors matching is improved, error rate is reduced, color curve, surface and solid can be displayed in multiple ways and zoomed and rotated discretionarily, which is convenient and practical.
Description
technical field [0001] The invention relates to chemical industry, in particular to a method for judging three-dimensional graphics of color matching of dyed pigments. Background technique [0002] At present, the color matching of ordinary dyes must be done by an experienced colorist. However, the human eye increases with age, which makes the vision tend to age, and it is easy to distinguish similar colors. During manual color matching, the proportion of the color samples of the three primary colors depends on the color matching master, which often causes errors when different people match the same color; when using software to simulate color matching, it is often impossible to display the closest color samples for color matching that cannot be matched The color sample area makes it impossible to complete the color matching, and for the color samples that can be matched, it is impossible to make various observations and display the color area where it is located, which need...
