RGB to CMYK Converter
Convert screen colors to print-ready CMYK percentages.
Convert an on-screen RGB color to its CMYK ink percentages for print work — with the honest caveat that final CMYK depends on the press profile.
CMYK conversion here is the standard formula without a printer ICC profile — real presses vary, so treat CMYK values as a starting point and let your printer do the final separation.
How it works
- Enter R, G, B values (or paste a HEX code).
- Read the CMYK percentages instantly.
- Copy values with one tap.
Frequently asked questions
Why does my printed color not match my screen?
Screens show light-based RGB colors, many of which sit outside what CMYK inks can physically reproduce — vivid blues and greens shift the most. Professional printers convert using calibrated ICC profiles; this tool uses the standard formula to get you close.
Does embroidery use CMYK?
No — embroidery uses solid pre-dyed threads, picked from numbered charts like Madeira or Isacord. Thread matching is part of every DigitEMB digitizing order.
