We know that RGB is additive color model and CMYK is subtractive color model. RGB starts with darkness (black) and we gradually add light; an CMY(K) image requires to be illuminated by white light.
When a printer performs printing operation, how do CMYK and RGB work together to print on white paper? And why does CMYK technology need both, white paper and white color?
N. B. - I want to understand the intuition rather than details. Please don't use too much technical term.
