== Halftoning ==
[[File:Halftoningcolor.svg|thumb|This diagram shows three examples of color halftoning with CMYK separations, as well as the combined halftone pattern and how the human eye would observe the combined halftone pattern from a sufficient distance.]]
{{main|Halftone}}
With CMYK printing, ''[[halftone|halftoning]]'' (also called ''screening'') allows for less than full saturation of the primary colors; tiny dots of each primary color are printed in a pattern small enough that humans [[color vision|perceive]] a solid color.<ref>{{cite book|url=https://books.google.com/books?id=nRoMo3V5AEwC&pg=PA1|title=Digital Color Halftoning|page=1|last=Kang|first=Henry R.|publisher=SPIE Press|year=1999|isbn=0-8194-3318-7}}</ref> Magenta printed with a 20% halftone, for example, produces a pink color, because the eye perceives the tiny magenta dots on the large white paper as lighter and less saturated than the color of pure magenta ink.{{citation needed|date=October 2020}} Halftoning allows for a continuous variability of each color, which enables continuous color mixing of the primaries. Without halftoning, each primary would be binary, i.e. on/off, which only allows for the [[color reproduction|reproduction]] of eight colors: white, the three primaries (cyan, magenta, yellow), the three secondaries (red, green, blue), and black.
