My trusty SG3110DN is at the end of its life and I've just bought an SG400 to replace it. In each case I use SG inks and Truepix paper, printing on standard mugs. I've set up VPM on my computer and am printing at 600dpi, but am getting really poor blacks (as the most obvious) compared to the SG3110DN using PowerDriver, nowhere near the same intensity. Anybody else encounter this when first using the SG400?
