Image to CMYK Color Separation

CMYK color separation is the process of splitting a full-color image into four component channels: Cyan (C), Magenta (M), Yellow (Y), and Key/Black (K). Each channel represents the amount of ink that will be applied during the printing process. This is essential for offset printing, screen printing, and other professional print workflows where each color is printed separately using dedicated plates or screens.

This tool provides a simulated CMYK separation based on sRGB color space conversion. It is excellent for preview, education, and preliminary proofing. For professional print production, you should use dedicated software like Adobe Photoshop with the appropriate ICC color profiles (e.g., FOGRA39, GRACoL) and consult with your print service provider for their specific requirements. Our tool does not account for dot gain, ink trapping, or paper stock characteristics.

Total ink coverage (TIC) is the sum of C+M+Y+K percentages at any given point. Most print processes have a maximum limit of 300-340%. Exceeding this can cause problems like ink not drying properly, smudging, paper curling, or ink peeling. This tool calculates the average coverage per channel and estimates the maximum total coverage. If you see a warning about high ink coverage, consider using a lower TIC setting in your design software or applying GCR (Gray Component Replacement) techniques.

In Color Tinted mode, areas with more ink appear more saturated in that channel's color — darker cyan means more cyan ink will be applied. In Grayscale mode (toggle off the color tint), darker areas represent more ink coverage, simulating traditional print films. White areas mean no ink of that color is needed. The Proof/Composite view simulates how all four inks will look when overlaid on paper.

Downloads are in PNG format. These can be used for reference, client presentations, or as a starting point for manual separation work in software like Photoshop or Illustrator.

Slight differences between the Original and Proof views are normal. This is because RGB and CMYK have different color gamuts — some vibrant RGB colors (especially bright greens, blues, and neon tones) cannot be perfectly reproduced with CMYK inks. The Proof simulates what the printed result may look like. This gamut difference is why soft-proofing before printing is so valuable.
