When preparing images for professional printing, RGB color mode is not enough. Printers work in CMYK (Cyan, Magenta, Yellow, Key/Black), and an RGB image sent to a print shop will be automatically converted — often with unpredictable color shifts. Switch & Shrink lets you control this conversion yourself using industry-standard ICC profiles. FOGRA39 is the standard for coated paper in Europe (ISO 12647-2). GRACoL 2006 is the North American standard for commercial printing. SWOP 2006 is used for publications and periodicals. By converting to CMYK before sending your files, you get consistent, predictable color reproduction and avoid unpleasant surprises when the printed piece comes back. The conversion is performed server-side using calibrated ICC profile data, ensuring accurate gamut mapping from RGB to the narrower CMYK color space.
Frequently Asked Questions
Why do I need to convert to CMYK for printing?
Printers use CMYK inks, not RGB light. If you send an RGB file to a printer, they will convert it automatically — but the result may not match what you intended. Converting to CMYK yourself gives you full control over the color output.
Which ICC profile should I choose?
Use FOGRA39 for European coated paper printing (the most common European standard). Use GRACoL 2006 for North American commercial printing. Use SWOP 2006 for North American magazine and publication printing. When in doubt, ask your print shop which profile they use.
Will the colors change after conversion?
Some color shift is normal and expected — the CMYK color space is smaller than RGB, so highly saturated colors may become slightly less vivid. The ICC profiles ensure the conversion is as accurate as possible within the CMYK gamut.
What file formats can I convert to CMYK?
Switch & Shrink converts JPG, PNG, WebP, TIFF, and BMP images to CMYK. Output is saved as TIFF or JPEG CMYK, depending on your settings.
