Frequently asked questions

Why CMYK?

Commercial printers use CMYK. Converting ensures colors print accurately.

Will colors look different after conversion?

Slight color shifts are normal when converting from RGB to CMYK because the color gamuts differ. Blues and greens shift the most.

Can I convert specific elements only?

The tool converts all color elements. Images, text, and vector graphics are all mapped from RGB to CMYK color space.

What ICC profile is used?

The default CMYK profile is US Web Coated (SWOP) v2. Contact us for custom ICC profiles for specific print workflows.
