Frequently Asked Questions
Not exactly — this uses a standard mathematical RGB-to-CMYK formula, which doesn't account for your specific printer, ink set, or paper's real-world color profile (ICC profile). For color-critical print work, get a proof from your print shop rather than relying solely on this conversion.
RGB is additive light (screens emit red/green/blue light) while CMYK is subtractive ink (inks absorb light off paper) — the two use fundamentally different physical processes, so some RGB colors, especially bright saturated ones, can't be reproduced exactly in CMYK ink.
No — the calculation happens entirely in your browser.
