11571886 · 2023-02-07 · ·

A printing apparatus prints an image by applying ink to a print surface of an inclined print medium using a print head. A control apparatus for the printing apparatus acquires information on an inclination of the print surface. Based on the information, printing is controlled according to a print condition corresponding to a magnitude of the inclination of the print surface.

An aqueous pigment dispersion includes at least one dispersing agent having the general formula: ##STR00001## The aqueous pigment dispersion can be used in an aqueous inkjet ink which is useful for printing on textile fabrics.

Method for manufacturing colored sheet and colored sheet

A method for manufacturing a colored sheet for coloring an object by adhesion to the object includes, a coloring step of applying by spraying, a first coating fluid containing first microp articles for coloring to a thin film of a print receiver body which has a sheet-shaped support body and the thin film, the thin film being peelably held on the sheet-shaped support body to serve as a base material of an adhesive sheet which is to be adhered to the object, and a restricting step of applying by spraying, before the coloring step, a second coating fluid for restricting the first microparticles from penetrating the thin film to a location where the first coating fluid is to be applied.

Ink jet printer for printing with variable gloss

The invention relates to an ink jet printer having a print carriage, a curing unit and a holder arranged to move a recording medium relative to the carriage assembly in a sub-scanning direction, wherein the print carriage is movable in a main scanning direction normal to the sub-scanning direction, and a print head unit arranged on the print carriage for printing a swath of an image onto the recording medium in each scan pass of the print carriage, the print carriage further having a mirror assembly arranged to deflect light from the curing unit onto an exposure area on the printed swath.

IMAGE RECORDING APPARATUS
20230102944 · 2023-03-30 ·

There is provided an image recording apparatus including: a conveyer; a carriage; a recording head; a memory; and a controller. The controller is configured to cause the conveyer to convey a recording medium in a conveyance direction such that dot recording ranges are partially overlapped with each other in the conveying operation. In a case that a predetermined condition is fulfilled, the controller is configured to cause the recording head to record a dot including a correcting portion by correcting discharge, and in a case that the predetermined condition is not fulfilled, the controller is configured to cause the recording head to record the dot including the correcting portion by ordinary discharge.

Thermal based drop detection

A system comprises a printhead including a nozzle, a temperature sensor and a processor. The temperature sensor detects the temperature of a location of a print surface upon firing the nozzle to eject a drop of printing fluid to the location of the print surface. The processor determines whether the nozzle ejected the drop properly using the detected temperature.

In a case where a line drawing, such as a thin line, is included within input image data, the output of a non-ejectable nozzle is compensated for while suppressing deterioration of reproducibility thereof. Based on positional information for specifying an abnormal nozzle in which an ejection failure has occurred among a plurality of nozzles arrayed in a nozzle column, a pixel value of a pixel on a pixel line corresponding to the abnormal nozzle and a pixel value of a pixel on a pixel line corresponding to another nozzle that is located in close proximity to the abnormal nozzle and in which no ejection failure has occurred are exchanged for the input image data. Then, halftone image data is generated by performing halftone processing for the input image data for which pixel value exchange has been performed.

A printing apparatus configured to perform printing while varying an amount of adjustment of a target of adjustment, executing: printing a first adjustment pattern on a printing medium; reading the printed first adjustment pattern to acquire a first adjustment amount; printing a part of a second adjustment pattern on the printing medium, the printed part of the second adjustment pattern corresponding to only a part of the amount of adjustment according to the first adjustment pattern; reading the printed part of the second adjustment pattern to acquire a second adjustment amount; setting a first parameter that is a result of adjusting the target of adjustment by using the first adjustment amount; and setting a second parameter that is a result of adjusting the target of adjustment by using the second adjustment amount.

Method of printing using overlapping printhead segments
11571914 · 2023-02-07 · ·

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.
