Abstract: Appearance data including at least color information and gloss information of an object to be reproduced is inputted. Color mapping is performed to map the color information into a color reproducible range of an appearance reproduction apparatus, based on information indicating an appearance reproducible range of the appearance reproduction apparatus. A gloss reproducible range, in which the appearance reproduction apparatus can reproduce gloss while keeping the color information after the color mapping, is obtained based on the information indicating the appearance reproducible range. Gloss mapping is performed to map the gloss information into the gloss reproducible range. An output signal to be outputted to the appearance reproduction apparatus is generated based on mapped appearance data including the color information after the color mapping and the gloss information after the gloss mapping.

Abstract: Systems and methods for replacing cells of an image based on some pre-determined metric are described herein. For example, systems and methods described herein may improve the functioning of a standard imaging system. For example, the systems and methods described herein may be used to post-process existing images in an imaging system based on one or more pre-determined metrics and improve the halftone images according to those pre-determined metrics.

Abstract: Examples of a method and a system for configuring an imaging system are described. These examples involve obtaining a random sample of area coverage representations and grouping these by an estimated color, such as a colorimetric value. In each group a selected area coverage representation is determined with respect to one or more imaging attributes. A color gamut based on the random sample and the selected area coverage representations are used to generate a color mapping from an input color space to an area coverage representation space for use by the imaging system.

Abstract: An image forming apparatus includes a communicator; a medium color input device; an image processor including a color image generator, an edge detector, and a corrector; and an image forming unit. The image processor performs a correction process that corrects first image data corresponding to a first color and second image data corresponding to a second color. The image processor performs the correction process by causing, based on medium color of the recording medium, a first edge of a first image that is in the first image data and a second edge of a second image that is in the second image data and initially correspond, to be distanced from each other. The image forming unit forms the first image and the second image in this order on the recording medium, based on the first image data and the second image data that are corrected by the image processor.
