You will appreciate how in print, the resolution of an image is related to the quality of the paper. For newsprint you will use coarse (80 LPI) screens and for high quality litho or gravure, fine (180 LPI) screens. Type is rendered at something like 2400 dots per inch on an imagesetter. On any computer screen, there is only one resolution for images and type alike - 72 pixels per inch. The size of the pixels may vary slightly from one monitor to another and even the size of the inches, but the 72 PPI resolution of a Web page represents the borderline between having visible individual pixels on the screen and their blending into one another to form a smooth image.
