Originally posted by Outis It end in .icm. I tried installing some other printers' ICC profiles without problems, so I ended up writing this printing service to see what they have to say. Anyway, I"ll let you know!
From the blurb.com support website:
Quote: Soft proofing and ICC Profiles in Lightroom
Lightroom does not support the CMYK color space, so our profile will not appear in Lightroom's ICC profile list.
Blurb's ICC profile is designed specifically for use in CMYK supported applications such as Adobe Photoshop.
Could this problematic profile of yours be for the CMYK colour space?
