(1) Drawing directly on the computer with printing colors can reduce color difference

(2) The printing color is CMYK, and the default computer software is RGB color mode, and the RGB ratio CMYK has richer and more accurate colors. If you use RGB for drawing and then print with CMYK, the printer will use similar colors for printing, resulting in color difference. In order to avoid the appearance of chromatic aberration, use the CMYK color mode when drawing. CMYK colors are dull and not as expressive as RGB. For the final effect of the printed matter, you have to get used to it.
