Abstract

Described is a method and a device for screen calibration for the true-to-original reproduction of surface colors, the spectral reflection distribution of which is known, wherein by setting parameters the screen can be influenced using software and an electronic controller in each partial region of the screen. The disclosure is characterized in that an observer adapts the reproduced color impression of the screen to the color impression of an original in each partial region of the screen, wherein the original is compared to the screen colors immediately thereafter on the screen surface and the screen parameters are varied until the color impressions of the original and of the screen appear identical to the observer on the respectively viewed partial screen, viewed from a predefined observer angle, and the settings performed are stored in a screen profile.
