Frequently Asked Questions

Why do CMYK and RGB look different?

CMYK describes ink on paper (subtractive), RGB describes light on screens (additive) — conversion is approximate because monitors cannot reproduce every printable color and vice versa.

What is K in CMYK?

K is the black channel (the 'key plate'); C, M and Y are cyan, magenta and yellow.

Can I convert CMYK to Pantone?

Pantone matching needs official ink libraries. This tool gives you the RGB/HEX equivalent, which you can match to the nearest Pantone swatch in design software.
