An analysis unit analyzes whether or not each of the plurality of partial data divided by the division unit is suitable for compression at any of a plurality of stages of image processing in which feature of image changes. A compression unit compresses the partial data at the stage when the analysis unit analyzes that it is suitable for compression. A decompressing unit decompresses the partial data compressed by the compression unit at the stage when it is compressed. A processing execution unit executes processing at the stage of image processing on the partial data decompressed by the decompressing unit.

Printing apparatus having an expandable housing and printing control method

A printing apparatus includes a printing head to move in a first direction, a conveying roller to convey the printing medium in a second direction intersecting with the first direction, and a housing to house the printing head and the conveying roller and be expandable and contractible in the first direction. The printing apparatus performs predetermined notification based on information related to a length of the housing in the first direction, wherein the conveying roller is incapable of conveying the printing medium having a predetermined size when the length of the housing in the first direction is a first length and conveys the printing medium having the predetermined size in a case where the length is a second length larger than the first length. The predetermined notification is performed based on the information related to the length of the housing indicating information corresponding to the first length.

20220413421 · 2022-12-29 ·

A method for reducing artifacts in an electrophotographic printing system includes receiving a print job including image data for a set of pages. The electrophotographic printing system is used to print a block of pages from the print job to provide corresponding printed pages. The image data for the block of pages is analyzed to determine an average toner usage rate. If the determined average toner usage rate for the block of pages falls outside an acceptable toner usage rate range, image data for a compensation image and a number of compensation images are determined such that the average toner usage rate will be brought back into the acceptable toner usage rate range.

Dosing ink for digital printing on reflective substrates

A computer-implemented method is provided for dosing ink in a digital printing device with multiple ink channels, when printing on a reflective substrate. A digital printing system configured with the method is also provided. Target color data of a target color to be printed on the reflective substrate is captured, including both color data and spectral reflectance data. The captured color data is processed with a printer model to output a preliminary dosing ratio for each ink channel. A digital opacity value for the target color is computed from the dosing ratio of each ink channel. A natural opacity value for the for the target color is computed from the captured spectral reflectance data, and a difference between the digital and natural opacity values is calculated. A predicted dosing ratio for each ink channel is obtained by interpolating the difference against an ink step of a diffuse ink component of the target color.
