Digital Print Quick Reference table (RGB)
It is most common, if not universal, to use RGB files for output from desktop printers.
A resolution of 72 dpi is most commonly used for on screen and website viewing.
200 dpi is for images to newsprint as well as the minimum requirement for Lightjet printing, although 360 dpi provides best results for the latter.
300 dpi is required for inkjet (desk top) printers to glossy paper.
Lamda prints are possible at 360 dpi, but are most detailed at 600 dpi.
The reference of file size below are for RGB color printing.
