I'd like to revive this thread because we're getting this on ArchiCAD 18 (6000 USA Full) with a Cannon C5035.
The problem occurs when printing from ArchiCAD, Acrobat, or Preview; although the problem areas appear different depending on what program we print from. There is nothing different about the splotchy area, in fact it is the same exact wall.
Very frustrating. Any ideas?
