The composition of the color spectrum

Printing color spectrum by various manufacturers including the following 4 parts: color, bi-color, tri-color, four color parts, because the premise differences, using objects, their composition, color display and colors, there's a definite difference in the number. Common use in chromatography to clarify local, will introduce the color spectrum of manufacturing and printing premises, using information and skills of primary parameters, fundamental data, and so on.

GC to clarify. Clarified in chromatography, introduced the fundamental form of chromatography, chromatographic wedges, screen angle, printing paper, ink and other materials testing premise, data and test data. The largest local in the chromatography (color part) monochrome part, Wong Ching is divided into, 15%, 3%, 5%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, 13, black 3%, 5%, 10%, 15%, 20%, 30%, 50%, 60% nine. In this way, changes various monochrome shades of color can be obtained. Bi-color parts, is the combination of yellow, magenta and cyan 22, wedges to identify two primary colors in accordance with horizontal and vertical display, each can constitute the two primary colors 13x13=169 colors, a total of 169x3=507 secondary colors can be combined. Tri-color parts, is in a two-color (magenta, cyan) on the basis of, in superposition in the third primary color (yellow) and black, combined to make the third color. A total of 6084 colors color. Four color parts, Wong Ching and black ink in accordance with wedges-dot area rate of disagreement are superimposed, overprint 18804 colors
