I am printing with an Epson 4800 using ColorByte's ImagePrint RIP using Phatte Black. I have never been able to get clean prints when printing double sidded on matte paper. I have no trouble printing the first side but when I print the back side I get what look like roller marks in the dark areas of the first image (as it passes through the printer for the second time, on the reverse of the paper). The roller marks are not from excess ink in the printer; it is as if the rollers are crushing the ink. It shows like a change in the finish of the paper, and it happens most in the dark areas. Has anyone experienced this before? I have tried printing with Plateen Gap at Widest and I've given the paper plenty of time to dry before printing the second side. I have also tried a few different print guard sprays which seem to help, but do not eliminate the problem. I am printing on StoneHinge and MOAB Chinle (entrada) paper/portfolio systems.
Any advise is appreciated.
