(2) The printing color is CMYK, and the computer software defaults to RGB color mode, which is much richer and more accurate than CMYK. If you draw with RGB first, and then print with CMYK, the printer will print similar colors, resulting in color difference. In order to avoid chromatic aberration, we use CMYK color mode when drawing. CMYK is dull in color, and its expressive force is not as good as RGB. For the final effect of printed matter, we can only get used to it.
