Has anyone ever had any problems with printing blue jeans on a fine art canvas gallery wrap?
We printed a small (11x14) gallery wrap of a family portrait for a client. The father was wearing blue jeans, and the print arrived with black, vertical banding over the blue jeans (nothing else, just the jeans).
We looked at the JPEG we had sent in to WHCC and, seeing no such flaws, resent the file and asked them to reprint. They reprinted it without question, but the second had the same flaw.
After this we inspected the JPEG again - at a wide variety of zoom ratios - and again saw nothing abnormal. Just to be sure, we looked at the RAW file as well, and it didn't have any abnormalities either.
Called up WHCC again and discussed some more. They said the applied a localized gausian blur to the jeans and it took care of the problem. They are going to send me a copy of the file with their edits to inspect, but I haven't seen it yet. The last guy we spoke to with WHCC said this is becoming a more common problem, although it typically manifests itself in men's shirts.
Has anyone else heard of this?
And how in the world do you prevent this if the problems aren't visible in the files?? Sounds like a printing problem to me, but I don't want to jump to conclusions.
