RGB vs CMYK
By Waleed Sheeraz, independent operator of A2Z Edit · Updated 2026-09-09
RGB mixes light on screens; CMYK mixes inks on paper. They are different worlds.
A2Z Edit’s RGB ↔ CMYK converters help you approximate values when coordinating digital and print.
Do this on A2Z Edit
Open the RGB to CMYK Converter and follow the steps below.
Open RGB to CMYK ConverterSteps
- Decide whether the deliverable is screen or press.
- Design on-screen in RGB/HEX for web work.
- Convert to CMYK when talking to a printer.
- Request proofs for brand-critical inks.
- Keep both values documented in the brand kit.
Why it matters
Expecting identical neon RGB on a press is a common disappointment.
Tips
- Start from printer-provided swatches when possible.
- Do not hard-convert photos casually without reviewing results.
- Use contrast tools for on-screen accessibility separately from print checks.
Screens are not presses
RGB is light on a display. CMYK is ink on paper. A naive math conversion is a conversation starter, not a contract proof. A2Z Edit labels these tools as approximate on purpose.
If a printer asks for CMYK, ask which ICC profile they expect. Do not send a screenshot of our converter as press-ready art.
Frequently asked questions
Which is better?
Neither—each matches its medium.
Can CMYK show all RGB colors?
No. Many bright screen colors fall outside CMYK gamut.
HEX in print?
Convert toward CMYK; printers do not run on HEX.
