Abstract
A hard copy reproduction is formed of a video image which is an accurate reproduction of the tonal luminance differences and color of the video image. A gray scale and color test image is formed on the video monitor screen and measured using a photometer. The gray scale and color test image is reproduced on hard copy and may be measured using a densitometer. The two sets of measurements are entered into a computer system and used to adjust, on a pixel-by-pixel basis, the electronic controls of the hard color reproduction system to compensate for any deviations from accurate reproduction.
