Descriptive of an image—either on a computer display or in printed form—that has a high number of dots per square inch. On computer screens and digital output devices, images are essentially composed of very small dots (technically called spots) which when put together in certain shapes, form the text or image that is output. The more spots per square inch, the sharper the image, and the greater the resolution. A high resolution image on a computer monitor is defined roughly as 1,000 x 1,000 pixels per 12-inch diagonal display, a resolution which tends to generate the most realistic-looking images and most effective color transitions. On output devices, high resolution may be 600 spots per inch or greater, depending on the image. Also called high-res. (See Resolution.)
