Raster

Raster graphics are resolution dependent. They cannot scale up to an arbitrary resolution without . This property contrasts with the capabilities of which easily scale up to the quality of the device them. Raster graphics deal more practically than vector graphics with photographs and photo-realistic images, while vector graphics often serve better for or for Modern computer-monitors typically display about 72 to 130 (PPI), and some modern consumer printers can resolve 2400 (DPI) or more; determining the most appropriate image resolution for a given printer-resolution can pose difficulties, since printed output may have a greater level of detail than a viewer can discern on a monitor. Typically, a resolution of 150 to 300 pixel per inch works well for 4-color process printing.
