Four colors are used for ordinary printing. The four basic colors C\M\Y\K are blue, red, yellow and black. With the different ratios of the four colors, any color can be combined. It's much smaller than the RGB color gamut, so in general, the screen display may exceed the printable color. So when making prints, pay attention to the spot color that is mainly applied to the color of some specific trademarks. Because the spot color is not just by four colors. The matching, so the four colors may not be able to deploy the spot color, so when printing, add a special color swatch, such as PANTONE color, it is necessary to use RGB, CMYK level 12 basic colors to make the simplest analogy, for easier Intuitive understanding is also green when painting. If there is green, you can use it directly. When the green is used up, you can only mix yellow and blue in proportion, and you can get green. It is green. What is the difference? The green color after mixing the two colors is reduced in the brightness and purity of the color. The green pigments that are not directly bought are bright and bright. The printing is done by mixing cmyk to obtain various colors. , and the spot color (that is, Pantone color) is not obtained by mixing four colors of cmyk.
