Technical question 6, the difference between RGB color and CMYK color?

Customers often have RGB color and CMYK color problems when submitting proofing materials. The documents provided by the customer are in RGB color, but in actual printing, the color must be in CMYK. Turning RGB to CMYK will cause a big change. What is the reason?

RGB color is commonly known as display color, which is the color displayed by the monitor. RGB color is difficult to be printed if it is not changed to professional printing in daily application, even if it is changed to professional color printing, some of the colors cannot be printed.

CMYK colors are printed colors and are composed of red, yellow, blue, and black. In printing, the color of the pattern is restored by matching the color ratio. CMYK colors are not as bright as RGB colors, but colors can achieve more than 80% in daily life. Especially in the pattern printing of the water cup industry, all CMYK colors are used, and each printing process is also used for pattern printing around these four colors.
