It's over my head I'm afraid. My comments have all been about utilizing multiple channels and inks to "extend" monochromatic scale. There is clearly much going on at the driver/printer level as well. That the Piezo driver addresses the printer differently than the Epson driver seems obvious. It's maximum allowable image area for a given page setup size is different, and watching the ink go down one can observe obvious clear bands or rows as it proceeds as opposed to the soft progression of ink the Epson driver puts down. I think this is part of the reason Jon says the driver doesn't dither. The definition of "dither" seems to be the problem, and in this case is more related to Photoshop's dither option than the actual creation of printing dots from pixels. I have seen RIPs that allow user adjustable "multi-pass" options, so there seem to be several options at driver level software design. I don't pretend to know anything about that end of things, just some dangerous uninformed suppositions. Tyler
