Printing common sense-ink color list
The results of subtractive color mixing are summarized as follows:
Yellow = white-blue
Purple = white-green
Cyan = white-red
Yellow + purple = white-blue-green = red
Yellow + Cyan = White-Blue-Red = Green
Purple + Cyan = White-Green-Red = Blue
Yellow + Purple + Cyan = White-Blue-Green-Red = Black
These relations indicate the relationship of the pigments added in sequence, and the brightness of the color obtained after mixing is reduced.
The paint coloring technology mainly includes solid color paint coloring, transparent paint coloring, etc. Generally, before formulating the coloring formula, it should be analyzed according to the color template or according to the color of a certain object. First, understand the hue range, which consists of several colors Composition, which is the main color, which is the secondary color, how is the relationship between the color and the color, what is the proportion of each, and then the coloring formula is initially drawn out based on experience, and then the sample is debugged. When coloring, first add the main color Color, and then use the color with strong coloring force as a pair, slowly and intermittently add and continue to stir, to observe the color change at any time, sample wipe, brush, spray or dip on a clean template, wait for the color to stabilize and the original template For color comparison, the principle of "from shallow to deep" must be mastered throughout the color adjustment process. It can be seen from the principle of the subtractive color method, if the sample is compared with the standard board, the excessive red can use the subtractive color method or add green, the excessive green can use the subtractive green or add purple, the excessive blue can use the subtractive blue or add yellow method to adjust , And vice versa, because yellow, cyan, purple and blue, red, and green are complementary colors, but this mixing of pigments will result in a decrease in brightness, and black and white can be used to adjust the brightness of the mixed color. At present, paint manufacturers generally prepare black, white, red, green, blue, yellow, cyan, purple and other color pastes for color mixing. When color matching of solid color paints, light color gamuts are often used in white base paints. The color concentration of less than 5% high-concentration color paste, and the use of varnish in the dark area to reinforce the quantitative color paste color mixing method. The transparent color is selected by some transparent pigment slurry or dye liquid. The color change of the transparent color is also affected by the thickness of the coating and the substrate. In the actual color comparison, it should be within the specified thickness and substrate For comparison. Knowing the basic knowledge of these paint toning, diligent in practice, will quickly master this technology.
