Tom said: >Keep these numbers in mind: > >600 DPI printer: 85 line screen (LPI) >720 DPI printer: 100 line screen (LPI) >1400 DPI printer: 150 line screen (LPI) > >Now, you need an image file that has a PPI of about double your target LPI. >(You can often get by with 1.5x.) So, a 600 DPI printer needs a 170 DPI >file. A 1400 DPI printer, like the Epson Photo needs a 300 PPI file. The Stylus Photo, I believe, is 720 X 720. The Stylus 800 is 1440 X 720. For printers like the 800 should we use the higher resolution, the lower, or in-between, when figuring possible LPI? Please understand I am not taking issue with Tom. Just a footnote. Nick Hunter
