Graphics
Resolution
Resolution can be broken down into two categories: image resolution and printer resolution. These are two entirely different measurements.
Image resolution refers to the pixel size of an image. In graphic arts terminology, image resolution refers to the number of pixels per inch in an image at the size it is to be reproduced.
Printer resolution refers to the number of laser passes the printer uses per inch to create an image. This is commonly referred to as dots per inch. A low resolution desktop laser printer would typically print at 300 dots per inch, whereas a high resolution imagesetter would typically be capable of printing at 3600 dots per inch. Just to indicate the difference between lpi, ppi (pixels per inch) and dpi . . . a 600 dpi printer could print a 300 ppi image at 100 lpi screen frequency.
