I don’t know if I did or not. Is there any way to look at the file to find out? I do know that the sample was printed from a 150dpi file(I had to downsize it because I forgot that I could use Dropbox to email large files) The last printing (the one that had the problem) was 300dpi.
Hmm… I don’t know. I’m sure there is software that could tell you if you knew what to look for… Is it possible to send me the sample AND the final file, so I can take a look? It would be a lot easier for me to do it myself, than to try to tell someone else how to look. 🙂 Scaling from 300 to 150 dpi won’t affect colors any, but if you selected a different preset (such as “web”) for getting a smaller file size, then it’s entirely possible that it did change some color settings somewhere.
