Four-color printing

Four-color printing, printing with subtractive color three primary colors (yellow, magenta, cyan) and black.

If you use a color ink other than the four-color inks of yellow, magenta, cyan, and black inks to copy the original color, you should not call it “four-color printing” but should be called “special color printing” or “point color.” print”.

Four-color printing is a lithographic method that achieves full-color reproduction by using the three primary colors of red, green, and blue and black colorants (ink or dye) according to the principle of subtractive color mixing.
