I've got a little problem I'm trying to work through over here. I have a few stand alone gerber files that were not part of any altium project. I can easily import them to altium, however I'm having a bit of trouble exporting them out to pdf's. And before somebody mentions it, yes I've tried gerbv. The problem is that it doesn't export accurately and seems to add color channels that screw up the printing process. Any help or suggestions would be greatly appreciated.
