An information processing apparatus includes a processor configured to: acquire a read image resulting from reading a recording medium where a diagnostic image to be used to diagnose an image forming apparatus is formed; acquire, from the read image, an image read portion of the recording medium from which the diagnostic image is read and one specific portion of a non-formation read portion, the non-formation read portion resulting from reading a non-formation portion of the recording medium where the diagnostic image is not formed; and output the image read portion and the one specific portion.

A color calibration method applied to an image-forming device includes: determining whether there is a first task which is an image-forming task being executed or an image-forming task to be executed; when the first task exists, acquiring a size of a first imaging medium corresponding to the first task; determining whether the size of the first imaging medium is within a preset range; and when the size of the first imaging medium is within the preset range, executing the first task and a color calibration task at the same time.

A printing apparatus includes an instruction unit configured to instruct a conveyance unit to convey a first sheet, and a detection unit configured to detect a size of the conveyed first sheet, the detected size being used for image processing for printing on a different sheet from the first sheet. The instruction unit is configured to instruct, before the detection unit detects the size of the first sheet, the conveyance unit to convey a sheet next to the first sheet.

An output product producing method includes acquiring output information, specifying an output condition for an output section, converting the output information into a code having an error-correction amount corresponding to the output condition, and causing the output section to output an output product including the code under the output condition.

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.

Provided is an image forming apparatus that suppresses degradation of performance of processing up to completion of printing while suppressing the occurrence of moire. A data-compression unit stores identification data indicating the presence or absence of periodicity obtained by analyzing printing data, and printing data correlated with the identification data in a first memory area of a RAM. A color-conversion-processing unit that performs a speculative process, causes printing data that has undergone a color conversion process corresponding to printer printing to be stored in a second memory area of a RAM. A screen-processing unit that performs a speculative process, performs an AM screen process on printing data. In addition, a system-control unit causes the image-forming unit to move from a printing pre-start position to a printing start position based on a determination result of a printing color in a color conversion process corresponding to a first printer printing by the color-conversion-processing unit by a speculative process.

In some examples, a supply component for a printing device includes a memory device comprising corrective data to produce a customized color table for a first color gamut, wherein the corrective data corresponds to nodes of a reference color table for the printing device that is able to employ a plurality of color gamuts for printing. The corrective data comprises a plurality of residual values to transform the nodes of the reference color table to the customized color table. The corrective data is accessible by the printing device to transform the reference color table to the customized color table used for printing to a media using the first color gamut.

A printing apparatus includes a processor that causes a conveyance unit to convey a first sheet to print an image on the first sheet in a free size printing mode, before a user instruction for starting printing is accepted, and causes the conveyance unit to start conveying a portion of sheets of a plurality of sheets following the first sheet to print a portion of images on the portion of the sheets following the first sheet, before detection of the size of the first sheet. The processor also causes, in the free size printing mode, the conveyance unit to start conveying other sheets, of the plurality of sheets, following the portion of the sheets following the first sheet, to print other images on the other sheets, in accordance with having confirmed detection of the size of the first sheet.

An image forming apparatus include an apparatus body, a cassette, and a size detector to detect a size of a sheet stored in the cassette. An image forming unit forms an image on a sheet fed from the cassette depending on a size setting and a type setting stored in a memory. In addition, a controller executes a first rewrite process to rewrite the size setting in a memory with size information acquired as a detection result of the size detector, if the cassette in an open state is closed, a determination process to determine whether the size information used for rewriting the size setting in the first rewrite process and the type setting stored in the memory satisfy a predetermined combination condition, and a second rewrite process to rewrite the type setting in the memory with predetermined type information that satisfies the combination condition with respect to the size information used for rewriting the size setting in the first rewrite process if the combination condition is not satisfied in the determination process.

The disclosure discloses a non-transitory computer-readable medium storing a printed-matter producing program for executing steps on a controller of a printed-matter producing apparatus. In a consistency determination step, it is determined whether or not medium specification information acquired is identical to medium specification information stored in a medium specification information storage memory. In a medium specification information replacement step, the stored medium specification information is not replaced with the acquired medium specification information in the case that the acquired medium specification information is identical, and the stored medium specification information is replaced with the acquired medium specification information in the case that the acquired medium specification information is not identical. In a printed-matter production step, a feeder and a printing head is controlled on the basis of one piece of the medium specification information stored in the medium specification information storage memory to produce a printed matter.
