FAQ
What formula does this use?
A common simplified conversion (K = 1 - max(R,G,B), C = (1-R-K)/(1-K), etc.). Real print results vary with ink, printer, and paper, so treat this as an approximation.
Why might this look different from what a print shop produces?
This is a simple mathematical conversion. Real printing involves ICC color management and ink/paper characteristics, so accurate color reproduction requires your print shopโs color management process.
What is K (the key plate)?
The black ink component. Mixing only cyan, magenta, and yellow to produce black gives poor results and costs more ink, so print processes use a separate black (K) ink.
