If color work: Have all photos, graphics or any other links have been opened and converted to CMYK format?
If RGB files exist within the document, there is a chance that the colors will not print correctly–regardless of how it looked on the monitor or inkjet printer. If you don t have the programs to do this correctly, one option we have is to open the pdf in Photoshop and convert the file to a CMYK PSD file and import into a layout program.* The downside to doing this is everything will be four color process, including black text. There is a risk of mis-registration or fuzzy type.
