In printing factory,there are four color printing and pantone color printing. but do you know the defference between them?

If you know that,it will be very useful for your printing packaging.

Four colors are used for ordinary printing. The four basic colors CMYK are blue, red, yellow and black. With the different ratios of these 4 colors, any color can be combined. It is much smaller than the color gamut of RGB, so in general, the screen display may exceed the color that can be printed. Therefore, when making prints, pay attention to the spot color mainly used for the color of some specific trademarks. Because the spot color is not only by four colors. The blending, so the four colors may not be able to match the spot color, so the printing must add a special color swatch such as PANTONE color will be composed of RGB, CMYK grade 12 basic colors. Make the simplest analogy, which is more intuitive to understand. It 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 proportionally. Toning, you can also get green, which is also green. What is the difference? The green color after the two colors are mixed, the color brightness and purity are reduced at the same time. The green pigments that are not directly bought are bright, bright and the same, printing It is a combination of cmyk to obtain various colors, and the spot color (that is, Pantone color) is not obtained by mixing four colors of cmyk, and there is no dot.
