Abstract: A color image processor is configured to locate at least two zones within a document. Within the zones, content types are recognized, wherein the content types may include: text and lines; graphic images; photographic images; and background. A color rendering intent is applied to each of the at least two zones based on the content type within the zone. The zones are then merged into an image.

Abstract: A method is provided of personalizing color reproduction of an output device by determining a user-specific color mapping. A user is enabled to individually select different color reproductions of a plurality of different test images according to the user's preferences, wherein the different color reproductions are associated with different color mappings. The test images are reproduced by the output device or a display device simulating the output device. The user-specific color mapping is determined by combining the color mappings of the selected color reproductions.

Abstract: A method for assessing color performance in a printing device, which is provided with color printing means for printing at least three primary color inks, comprises the steps of: (a) providing a printing file for printing at least one color scale, said scale comprising: a plurality of colored regions defined by substantially equal amounts of a first primary color ink and of a second primary color ink and a variable amount of a third primary color ink, said amount of third primary color ink increasing progressively from each region to the adjacent region in one direction of the scale, and a transition region defined by substantially equal amounts of the three primary color inks; (b) printing said printing file with said printing device to obtain a printed color scale; and (c) visually analysing the printed color scale to assess the performance of said color printing means for printing said third primary color ink, on the basis of the position of the transition region along the color scale.
