CMYK Color Converter
Screens and printers make colour differently. See a rough ink mix for your colour.
Examples: #007756, rgb(0, 119, 86) or cmyk(100, 0, 28, 53).

For pros
Why screen and press colours differ
A screen mixes red, green and blue light (RGB). A press mixes cyan, magenta, yellow and black ink (CMYK) on paper. Some bright blues, vivid greens and neons on a screen cannot be matched with four inks. See our CMYK vs RGB guide.
How this tool converts
K is 1 minus the largest of R, G and B (each from 0 to 1). C, M and Y are what is left once K is taken out. No colour profile (ICC) is used.
A printer converts with a profile for its press and paper, so its numbers will differ from these. Ask your printer for their profile.
Rich black
Rich black adds other inks to black for a deeper black on large areas. Our file guide gives C60 M40 Y40 K100, which is 240% total ink. Recipes vary, so ask your printer for theirs. Use plain K100 for text under 12 pt.
Total ink
Total ink is C, M, Y and K added together. Our print-ready file guide gives 300% as the usual limit. The very dark and very light notes are Printulu's working rules.
Frequently Asked Questions
What is the difference between RGB and CMYK?
RGB (Red, Green, Blue) is used for digital screens and creates colours by adding light. CMYK (Cyan, Magenta, Yellow, Key/Black) is used for printing and creates colours by subtracting light with ink. Colours can look different when converted between the two.
Why should I convert to CMYK before printing?
Printers use CMYK ink. If you send RGB, the printer converts it for you and colours can shift. Checking in CMYK first shows roughly what to expect. Only your printer's proof shows the real result.
What is total ink coverage?
Total ink coverage is the sum of all CMYK values. Most printers recommend a maximum of 300% total ink coverage to prevent ink bleeding and drying issues.
What is Rich Black?
Rich Black is a deeper black made by adding cyan, magenta and yellow to black ink (typically C:60 M:40 Y:40 K:100, which is 240% total ink). It gives a richer, darker black for large areas. Use plain K:100 for small text.
