An information processing device includes an acquisition unit acquiring image data and status data, a transmission unit transmitting, to a server, the image data and the status data, a reception unit receiving, from the server, first data generated by the server based on the image data and the status data, a storage unit storing the first data received by the reception unit and second data, and a control unit, wherein the first data is data defining a learned model learned by machine learning, the learned model being configured to, when the image data and the status data are input, output fabric data indicating a feature value of the fabric, the second data indicates a correspondence relationship between the fabric data and a recommended parameter, and the control unit derives, based on the first data and the second data, the recommended parameter from the image data and the status data.

A first conveyance path and a second conveyance path are formed in a housing. The first conveyance path extends in a conveyance direction to reach a first discharge port for discharging a sheet. The second conveyance path extends in the conveyance direction at a position higher than the first conveyance path to reach a second discharge port for discharging a sheet. The second discharge port is located at a position upstream of the first discharge port in the conveyance direction. A first print engine is provided at the first conveyance path. The first print engine is configured to print an image by using a recording agent on a sheet conveyed along the first conveyance path. A second print engine is provided at the second conveyance path. The second print engine is configured to print an image by using a recording agent on a sheet conveyed along the second conveyance path.

An information processing device processes information related to a printing process performed by an inkjet device drawing an image onto a fabric and at least one of a pre-processing device performing pre-processing on the fabric before an image is drawn and a post-processing device performing post-processing on the fabric after an image is drawn, the information processing device including an acquisition unit acquiring image data and original image data, the image data being obtained by digitizing, as an image, the fabric on which the printing process is performed, the original image data being original data of the image drawn on the fabric, a transmission unit transmitting, to a server, the image data and the original image data, and a reception unit receiving, from the server, an image quality parameter obtained by quantifying, by the server, image quality of the image data with respect to the original image data.

Misalignment of printing positions between print heads associated with thermal expansion is reduced without increasing a data processing load. To this end, printing element substrates in a reference head and an adjustment target head are adjusted to a target temperature, and a liquid is circulated through the print element substrates. After thermal expansion of the reference head and the adjustment target head reaches a steady state, a first printing region being a printing region of the reference head and a second printing region being a printing region of the adjustment target head in a longitudinal direction are obtained from an image printed by using all printing elements. Then, used regions to be used for actual printing are set among the printing elements arranged on the reference head and the adjustment target head based on the first printing region and the second printing region.

A printing system is described herein. The printing system has a massive base disposed on a flotation support, a flotation substrate support disposed on the base, a print support comprising a printhead assembly support and an auxiliary support, a printhead assembly coupled to the printhead assembly support, and a printhead supply assembly coupled to the auxiliary support.

A digitally printed security document includes: a security document substrate; a first digitally printed print working on a first surface of the substrate in a first region, the first print working including a first array of printed elements arranged according to a first grid of lattice points having a first pitch; and a second digitally printed print working on the first surface of the substrate in a second region, the second print working including a second array of printed elements arranged across a second grid of lattice points having a second pitch different from the first pitch.

A method of printing an image using a printing system including at least first and second overlapping printhead segments, the method includes the steps of: feeding media past the printhead segments along a media feed direction; determining an extent of wander of the media in a direction perpendicular to the media feed direction; selecting a stitching method based on the determined extent of wander; and printing the image using the first and second printhead segments. The printing step includes stitching the first and second printhead segments using the selected stitching method.

A modular textile printing apparatus is made up of multiple modules which are combined together. Each module has one rail for bearing a printing functional unit such as a print head. A second rail perpendicular to the first rail faces the first rail, and carries a printing tray or platen holding items to be printed. The tray moves along the rail. A third rail parallel to said second rail and facing away from the printing functional unit, is also for carrying the tray. The modules are connected together and the apparatus provides a starting point for loading and unloading the trays. The second rails are aligned with each other to form a continuous printing feed along the modules and the third rails are aligned to provide a return path after printing to the starting point for reloading.

There is disclosed a printhead control method, printhead controller and printer. The method may comprise determining whether ink drop variability is likely to occur based on a first time period in which a printhead is uncovered during a print action but before printing begins, and a second time period that is a minimum period for ink drop variability to occur when the printhead is uncovered. The method may further comprise setting a printhead firing frequency for the print action based on the determination.

In one example method, a determination is made via a processor that a document is to be printed using a printer including a printhead assembly and a printhead accessory based on a received print job. A determination is made via the processor that a first portion of the document is to be printed by the printhead assembly and a second portion is to be printed by the printhead accessory based on a characteristic of the printhead accessory. The first portion of the document is printed via the printhead assembly and the second portion of the document is printed via the printhead accessory.
