Why do RGB to CMYK values vary between tools?

CMYK values depend on print profiles, paper, ink and software settings. A browser converter can provide an RGB-based approximation, but professional apps may use ICC profiles.

Can I use RGB to CMYK values for final print?

Use them as a starting point for planning. For final production, convert and proof colors with the ICC profile required by your printer.

CMYK stands for cyan, magenta, yellow and key black. These channels describe ink amounts used in many print workflows.

Convert RGB to CMYK

CMYK is used for print workflows, but browser colors are displayed in RGB. This converter gives an RGB-based CMYK approximation, which can vary in professional tools depending on ICC color profiles.

Use it to estimate print-oriented values from screen colors, compare nearby CMYK-like samples, and prepare a color conversation before sending artwork to Illustrator, Photoshop or a print provider.

Important print note

RGB to CMYK conversion is not universal. The final result changes with the selected ICC profile, paper type, ink system and printer setup.

RGB to CMYK FAQ

Why does CMYK look different in Illustrator?

Illustrator and Photoshop use ICC color profiles. This tool gives a mathematical RGB-based approximation, so print software may show different values or previews.

Can I use these CMYK values for final print?

Use them as a starting point. For final production, check with your printer and convert colors inside the correct print profile.

What does K mean in CMYK?

K is the black channel. It controls how much black ink is added to cyan, magenta and yellow.
