I have a Epson 3800 and I have been printing a PSD file from my windows laptop and everything works fine, checked colour profile and everything is the same. The Mac has CS4 and the laptop CS3, I let the printer handle the colours. When I print from the Mac the colours come out dull and flat. I am using Epson Velvet Fine Art Paper 13 X 19. Just wasted 2 sheets plus ink! Damn what the hell is wrong?
