Self-configuring inspection systems for printers
Systems and methods are provided for print review systems. One embodiment is a print review system that includes a memory that stores inspection parameters of print media marked by a printer, an interface that communicates with the printer, and a controller that, in response to the printer initiating processing of a print job, receives an indication via the interface of settings used by the printer in processing the print job, modifies the parameters based on the settings, inspects the print media based on the modified parameters, and reports compliance of the print job with the modified parameters.
Image forming apparatus and flushing control method for assigning respective dot patterns for use in flushing with inks of different colors according to number of overlapping dots in image
An image forming apparatus includes a recording head that ejects inks of different colors on a recording medium to form an image based on image data, a storage device that stores a plurality of different dot patterns for flushing, and a control device that functions as: a controller that allows the recording head to make flushing; an image area detector that detects an image area in the image data; an overlapping dot counter that counts a number of overlapping dots for each of the plurality of dot patterns according to which flushing is to be made on the image area, the number of overlapping dots being a number of dots in the dot pattern of the ink ejected on the image area; and a dot pattern assignor that assigns, according to the number of overlapping dots, the respective dot patterns for use in flushing with the inks of different colors.
PLATEN WITH EDGE SPIT OPENINGS
Examples of a platen for a printing device are described. In some examples, the platen may include a spit opening located at a side of the platen. In some examples, the spit opening may include an angled lead-in edge to facilitate travel of print media in the printing device. In some examples, an inside portion of a leading edge of the print media contacts the angled lead-in edge of the spit opening and pulls an outside edge of the print media up as the print media moves across the platen.
INK-JET RECORDING APPARATUS
An ink-jet recording apparatus includes a recording head, an irregularity detecting unit, a recording medium conveyance unit, and a control unit. The irregularity detecting unit detects an irregularity with the recording medium conveyed toward the recording head. The recording medium conveyance unit has a recording medium diversion unit into which the recording medium with which an irregularity has been detected by the irregularity detecting unit is conveyed. The control unit can perform flushing operation and, when the irregularity detecting unit detects an irregularity with the recording medium, the control unit cancels the flushing operation set immediately before the recording medium with which the irregularity has been detected and conveys, by controlling the recording medium conveyance unit, the recording medium to the recording medium diversion unit.
Printhead and printhead maintenance
Printing liquid is spat from ai least one printhead nozzle onto a printing medium in a spitting zone when the printhead traverses the spitting zone during printing. The spitting zone is an area of the printing medium located at least partially in a second half of the printing medium in the direction of printhead travel, and wherein a centre point of the spitting zone is located in the second half of the printing medium in the direction of printhead travel.
Image forming apparatus
When performing on-sheet preliminary ink ejection, a control unit (a) determines a nozzle that performs the on-sheet preliminary ink ejection, (b) randomly selects on a print sheet an ejection position candidate of an ink droplet ejected from the determined nozzle, (c) determines whether the selected ejection position candidate is included by a mask area that includes a postprocessing object, (d1) if the selected ejection position candidate is not included by the mask area, sets as the selected ejection position candidate an ejection position of an ink droplet ejected from the determined nozzle, and (d2) if the selected ejection position candidate is included by the mask area, does not set as the selected ejection position candidate an ejection position of an ink droplet ejected from the determined nozzle and sets an ejection position of an ink droplet ejected from the determined nozzle outside of the mask area.
PRINTING METHOD FOR USE IN MANUFACTURE OF DISPOSABLE WORN ARTICLES
A method including: a conveying step of conveying a continuous sheet to be a component of a disposable worn article in a longitudinal direction; a printing step of repeatedly printing a predetermined pattern by spraying ink from a first group of nozzles of an inkjet print head onto a surface of the continuous sheet; and a flushing step of performing a flushing operation of spraying ink from at least a second group of nozzles of the head onto the surface of the continuous sheet.
TEXTILE PRINTING
It is hereby disclosed a textile printing method comprising a controller to: receive a print job; and determine a print area of a garment based on the print job; wherein the controller is to instruct a printhead comprising a pre-treatment liquid to eject a pre-treatment liquid in a pre-treatment area of the garment being the pre-treatment area associated to the print area; and to instruct a printhead comprising printing fluid to print the print job on the print area.
Method and apparatus for printhead maintenance
In an example, there is provided a method and apparatus for controlling spit on page operation, the method comprising receiving at least one image to be printed, for each row of a plurality of rows of the image: identifying two or more pixels of the row of the image to be printed by a nozzle of a printhead, determining if a spacing between two consecutive pixels of the two or more pixels is greater than a threshold distance, and in response to a determination that the spacing between the two consecutive pixels is greater than the threshold distance, providing an indication that spit on page dots should be provided when printing the image.
Safety zone for a maintenance task
Examples relate to a method to print a print job. The method comprise comparing an operational parameter of the print job with a reference operational parameter and determining to perform a maintenance task during the print job based on at least a result of comparing the operational parameter with the reference operational parameter. If the maintenance task is to be performed, the method further comprises determining a safety area on a printable medium and performing a maintenance task on a printable medium.
