For color or greyscale pictures that are (like) photos, 150 dpi in final si= ze is mostly enough, even for quality offset printing. =84In final size=93 =3D not scaled up If you have fine lines, like diagrams or scanned text, you might need 300 d= pi. For black & white lineart, you should use the resolution of your printe= r, but even for offset printing 800 dpi is enough (more than 1200 dpi are a= lways nonsense).
