4' x8' yeah sure, work at 150ppi. That's fine.
But a 30' x 41' banner at 150ppi would be over 14.5 gigs flat! Your printer is gonna hate you! Actually he might laugh when you send in your hard drive...
I am looking for a good photo only dye sublimation (thermal transfer) printer and have been looking at the Kodak 1400 professional. Anyone every use one and if so any pros/cons? I need something to run our prints on and while inkjet does a good job, i am just not that happy with the long lasting ability of inkjet prints. supposedly the 1400 laminateds as well as prints the photos and dye sub is supposed to last 100 years without fading versus only a few years for inkjet prints.
