In some examples, a supply component for a printing device includes a memory device comprising a plurality of corrective data to produce a corresponding plurality of color tables each customized for a respective media type of a plurality of media types, wherein a respective corrective data of the plurality of corrective data corresponds to nodes of a reference color table for the printing device that is able to accept the plurality of media types for printing. The respective corrective data includes a plurality of residual values to transform the nodes of the reference color table to a customized color table for use with a selected media type of the plurality of media types.

White-balance is improved when printing on colored media, while minimizing the time and use of costly materials required by present approaches. In an embodiment, the typical solid white fill or background layer is altered by including in the white layer one or more of the other colors already available in the printer to shade this layer. Thus, a small amount of cyan, for example, helps balance a pink-ish (red) media; yellow is used for blue media; and magenta is used for green media; as well as combinations thereof. A combination of transparent process inks and opaque white helps to maintain brightness (luminosity).

An image-processing apparatus generates data to be outputted to formation unit which form a shaped article on a recording medium. An acquisition unit acquire first shape data that represents a shape of unevenness. A first generation unit generates edge data that represents a shape of an edge of the unevenness, based on the first shape data. A second generation unit generates first recording amount data that represents a recording amount of a first recording material that is used to form at least a part of the edge in the edge data on the recording medium, or first dot arrangement data that represents dot arrangement of the first recording material on the recording medium, based on the edge data.

A transform wrapper is stored on a memory device and the memory device may be included in a printer cartridge. The transform wrapper may dynamically build a transform map for a printer based on metadata stored at the memory device. The metadata may indicate at least one of a type of depositing material, transform map, print media and printer.

Systems and methods manage information relating to paper media to enhance the quality of printing by printers. Systems and methods efficiently maintain color management profiles for different papers and ensure that the most appropriate (e.g., optimal) color management profile is employed for color conversion on a specific paper. In particular, embodiments may employ dynamic management of data stored in paper catalogs of printing systems. As such, a paper catalog of a printer device can effectively associate a paper with a color management profile that provides the best possible color reproduction on that paper.

An information processing apparatus, an information processing method, and a storage medium that execute density characteristics acquisition processing at an appropriate timing are provided.

An image forming apparatus including a plurality of sheet feeding cassettes includes a control unit. The control unit performs control. In a case where a predetermined condition is satisfied during execution of a print job to print image data, the control unit performs control to execute interruption processing of a correction job to print a correction patch. The control unit performs control to determine, from the plurality of sheet feeding cassettes, a sheet feeding cassette to be used for the correction job based on information on the sheet feeding cassette used for the print job.

A color printing system includes a printing device and other components that use color printing resources, such as calibration and ICC profiles, to complete color printing operations. These color printing resources are used for a large number of paper types stored in a paper catalog. The paper types can be further placed into paper groups within the paper catalog. The paper groups may be formed by assigning new papers into the paper catalog to those having paper types with existing calibration data and ICC profiles. These relationships are shown in a paper catalog map. The print shop can use the paper catalog map for selling paper types, providing different capabilities for paper types, and other information. The paper catalog map also may be used to select a paper type from a primary paper type and a secondary paper type.

A method of operating a printer separates the image data content of a sheet in a print job into multiple color separations. The first color separation printed on the sheet includes at least two fiducials printed in the least perceptible color of ink in the printer. The at least two fiducials are used to identify the process direction and skew of the printed sheet before the remaining color separations are printed on the sheet with the first color separation.

An image forming apparatus includes: an image forming unit configured to form an image onto a sheet; a conveyance roller configured to convey the sheet through a conveyance path, the conveyance path including a curved path being bent; a sensor configured to read the image formed on the sheet conveyed through the conveyance path by the conveyance roller, the sensor being configured to read the image formed on the sheet when a part of the sheet is conveyed through the curved path; and a controller configured to obtain information related to a type of the sheet, and to control, based on the information, a conveying speed of the sheet conveyed by the conveyance roller when the sensor reads the image.
