ABSTRACT:
A system and method for previsualizing print images interactively on a computer display simulating appearance of the printed image. Quality of the display is sacrificed to the level of a printed image by adding a linear offset to the brightness of each pixel on the display to match the flare of the print, and thereby simulate appearance of a print. By selectively removing this flare from one or two of the primary colors of a pixel, the illusion is presented of a color with higher saturation than normally produced with the phosphors of the display. These expanded colors match colors possible in a print image but not previously possible in a display image. Image appearance in the two different media are further matched by adjusting the gamma of one to match equal marginally perceptible steps of gray across the grayscale individually for each of the three types of color sensors in the retina, accounting for color crossover in the sensors.
