I'm confused about that. If Piezo is your output medium, the ALWAYS scan at the full resolution of the scanner. ALWAYS. Do NOT use any interpolation in PhotoShop when you resize your image. Let the PPI fall where it does. The Piezo driver wants as much resolution as it can get. The Piezo driver has to convert the grayscale image to the four inks, and you really only want one conversion in the process (the driver), or you degrade your image more than you need to. There has been some misinformation about "magic" printer PPI...and there is NONE for grayscale images. These "magic" PPIs are ONLY for line art (text/graphics that only contain pure black ink, no halftoning). They do NOT apply to Piezo at all, Piezo has NO "magic" PPI. - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
