File Conversion Tools
Convert color RGB parameters to CMYK models for print designs.
Follow these simple steps to get instant, accurate results directly in your browser:
Input Red (0-255), Green (0-255), and Blue (0-255) channel values.
Review Cyan %, Magenta %, Yellow %, and Black (K) % ink distributions.
Copy the formatted CMYK string (e.g. cmyk(0%, 50%, 100%, 0%)) for prepress documentation.
The RGB to CMYK Converter translates digital additive RGB screen colors (Red, Green, Blue from 0 to 255) into subtractive CMYK process printing ink percentages (Cyan, Magenta, Yellow, Key/Black from 0% to 100%).
Digital computer screens generate colors by emitting additive light mixtures of red, green, and blue. Commercial four-color process printing (offset and digital printing presses), however, applies subtractive inks of cyan, magenta, yellow, and black onto white paper. This tool calculates standard four-color subtractive ink percentages, ensuring graphic designers avoid out-of-gamut color shifts before sending files to print.
Calculations execute locally in your web browser with zero server delay, complete with live print ink breakdown charts.
Calculates C, M, Y, K percentages using standard subtractive color space formulas.
Calculates total ink limit percentage (TIC/TAC) to prevent over-inking on press.
Displays digital screen RGB swatch alongside estimated CMYK rendering.
Your proprietary brand colors are calculated locally with zero server uploads.
Translate web and digital screen brand colors into CMYK ink formulas for brochures and business cards.
Obtain baseline subtractive color coordinates for digital design drafts and collateral mockup.
Provide commercial printers and prepress technicians with initial mathematical four-color ink estimates for further RIP/ICC profiling.
