CMYK Fallback Profile

cmyk-fallback-profile

The cmyk-fallback-profile parameter controls which ICC color profile is used as a fallback when converting CMYK images to sRGB during rendering. It applies when the source image is in CMYK color space but does not have an embedded ICC profile.

cmyk-fallback-profile accepts the following values:

  • swop — SWOP (Specifications for Web Offset Publications), a US web offset printing standard
  • fogra39 — FOGRA39, a European offset printing standard
  • generic — A generic CMYK fallback profile

When cmyk-fallback-profile is not specified, a default profile is applied automatically.

When does this parameter apply?

This parameter only has an effect on CMYK images without an embedded ICC profile. CMYK images that include an ICC profile will use that embedded profile for conversion. Images in other color spaces (sRGB, Adobe RGB, etc.) are not affected.

For more information about how Imgix handles color space conversions, see the cs (Color Space) parameter.
