It depends on what you mean by "working with". If you do any tonal corrections (aside from very very very minor ones) with 8 bit data, you will get posterization. If you want to work with 8 bit files, get the tonality correct in the scanner driver (which means it is done using high bit data). Do you know what is meant by "tonal corrections" as opposed to changes that do not change the tonal curve? > If > I use the Epson 2200 printer, am I limiting the output quality? That depends on the printer, printer driver, and how you print. The human eye can only see, at most, a few hundred graytones in any give lighting. Some of the quadtone systems (like Piezography) smooth the tonal transitions so though you can't distinguish the different tones, the transition is smooth between them. This is a good thing. I am not familiar with the 2200. Does the 2200 use more than one ink for printing B&W? If so, you are subject to a dither pattern using only one ink, which is far inferior to using quadtone inks (four tones). If you are dedicating this printer to B&W printing, you might want to consider getting quad/hex tone inks for it and either using the piezography driver (if it supports the 2200) or something like Paul Roark's curves. If you want more info on any of this, please ask. Regards, Austin - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
