Version 4 ICC files do not seem to work with MacOS 11 and Affinity Photo.
After contacting the paper company and working through my problem, we discovered that using version 4 ICC files when printing from Affinity Photo produce an incomplete print. In my case just yellow and light cyan. They kindly sent me a version 2 ICC profile of the same file, and it worked.
Has anyone else been having this problem?
