Frequently Asked Questions

Why are RGB and CMYK different color spaces?

RGB is an additive color model used for screens (light is combined), while CMYK is subtractive (ink absorbs light). Some bright screen colors cannot be reproduced in CMYK print.

How accurate is this RGB to CMYK conversion?

This tool uses a standard mathematical conversion. For professional print work, a color-managed workflow with ICC profiles will give more accurate results depending on your paper and printer.

What does the K in CMYK stand for?

K stands for Key, which refers to the black ink plate (the key plate in the printing process). Using K instead of B avoids confusion with Blue in RGB.
