1. To print, use cmyk mode.

2. The color area of ??cmyk mode is smaller than rgb, and there are some bright colors that are not found in cmyk

3. The colors are very bright and beautiful. It is a problem of 4-color mixing. Pure and single colors are gorgeous. The mixed color will be darker, because the more mixed the cmyk is, the darker it will be, and the more mixed the rgb will be, the brighter it will be, such as bright red, which is two colors of magenta and yellow. Adding cyan will make it darker, but if you want a deep red, you need to add cyan, and if you want it dark, add black. Just need to lower cmyk. There are also color management files, you can set Japanese ones, which are generally brighter and brighter than European and American color files. .
