Opening/Viewing OPPO file January 27, 2012, 01:18:45 PM Running Nexus 9.0.3. Anyone know how I can open an OPPO file (.opo)? I use InSight to open or edit PSTI files, but that will not allow me to open OPPO files. Printer is insisting that files I gave them for a previous job were not trapped. The workflow I use for their stuff creates a trapped Artpro file which then among other modules goes through a Print File to Nexus Module where the OPPO file and link are produced. I opened all the Artpro files (in Artpro) and they all have trap. The proofs I made are from the OPPO file and the trap is visible in the proof. I give the printer the Artpro file with mapped tiffs as well as the .opo file and low res link. I don't want to get into a pissing match with the printer. I just want to make sure I have all my ducks in a row before the next round of work comes through that will going to the same printer. This is the only printer I have ever had to supply an OPPO file to.As an aside, I am strictly doing the prepress on this and I believe that printer is just trying to make my company look bad so they can do the prepress as well. I'm sure nobody has heard that one before..... I attached screen capture of the workflow if that helps. Thanks again in advance.
