'100 dpi at full size is plenty big enough for digital input. The rip software takes care of the rest. The only time you need 150 to 300 dpi is when youre going to film.' are you sure on this? I work at a print firm where we routinely work at 300dpi on a Kamori 5 stage printer.. I asked them today about printing at 100dpi for 'fine art'.. I won't repeat the reply since children may be reading.. but the general concencous was 'are they kidding???'
