When designers output screen artwork for print, color distortion often occurs due to the gamut differences between RGB (screen light model) and CMYK (print ink model). This tool uses standard ICC algorithms to achieve bidirectional conversion between the two color modes. Inputting the rgb(R,G,B) format (where R/G/B are integers from 0-255) outputs the cmyk(C,M,Y,K) format (where C/M/Y/K are percentages from 0-100), and vice versa. RGB is defined as the intensity values of the three primary colors in the additive color model, while CMYK is defined as the concentration ratio of the four inks in the subtractive color model.
It must be an integer between 0 and 255. Values outside this range will be automatically corrected to the nearest boundary value.
Because the RGB color gamut (approx. 16.7 million colors) is larger than the CMYK gamut, some highly saturated colors are compressed into the printable ink range during conversion. We recommend using this tool to test key color values before printing.
Inputs must follow the rgb(R,G,B) or cmyk(C,M,Y,K) syntax structure and are case-sensitive. Conversion results are for reference only, as actual print results are affected by paper and ink characteristics. Sensitive data is not stored on our servers.
We recommend designers convert key RGB colors (e.g., a brand color like rgb(0,102,204)) to CMYK to test for color shifts before printing. A typical example is pure red rgb(255,0,0), which converts to cmyk(0,100,100,0); the actual print may lean towards orange and require manual adjustment of the black proportion.
