About RGB to CMYK Converter
CMYK is the color model used in color printing, standing for Cyan, Magenta, Yellow, and Key (Black). While screens use additive RGB color, printers use subtractive CMYK. Converting from RGB to CMYK is essential when preparing digital designs for print, as the color gamuts of the two models differ. Note that this tool provides a mathematical approximation; actual print results may vary by printer profile. All calculations happen entirely in your browser.
