The artist who does most of the work for the Daytona shop I printed at doesn't understand the concept of "spot color". The guy is a good artist, does some stuff now for Disney, but I don't know if he was just so hard-headed and arrogant that he thought that was beneath him, or just plain lazy. The owners had to discect his files to output film. From what I understand, they tried to explain it to him but he just never "got it". An he was no kid -- gotta be in his 40s.
