The present disclosure relates particularly but not exclusive to a method for printing in a multipass print mode using a first printhead (PT1) and a second printhead (PT2), the method including printing in a first pass a first image in a first area of a print medium using a first set (ST21) of nozzles (N5-N24) from the first printhead (PT1), printing in a second pass a coating layer over the first image using a second set (ST22) of nozzles (P4-P22) from the second printhead (PT2), and printing in a third pass a second image over the coating layer using a third set (ST23) of nozzles (N1-20) from the first printhead (PT1).

A printing apparatus to which a consumable part filled with a printing material can be detachably attached, so as to perform printing according to a color mode setting by use of the printing material filled in the consumable part whose type differs according to a contract, includes: a setting unit configured to set a contract status, based on information related to the contract; a first obtainment unit configured to obtain a set color mode; a second obtainment unit configured to obtain the type of mounted consumable part which corresponds to the contract status; and a print control unit configured to control printing by allowing or restricting the printing, based on the contract status that is set by the setting unit, the color mode that is obtained by the first obtainment unit, and the type of consumable part that is obtained by the second obtainment unit.

A repeatable manufacturing process uses a printer to deposits liquid for each product carried by a substrate to form respective thin films. The liquid is dried, cured or otherwise processed to form from the liquid a permanent layer of each respective product. To perform printing, each newly-introduced substrate is roughly mechanically aligned, with an optical system detecting sub-millimeter misalignment, and with software correcting for misalignment. Rendering of adjusted data is performed such that nozzles are variously assigned dependent on misalignment to deposit droplets in a regulated manner, to ensure precise deposition of liquid for each given area of the substrate. For example, applied to the manufacture of flat panel displays, software ensures that exactly the right amount of liquid is deposited for each “pixel” of the display, to minimize likelihood of visible discrepancies in the resultant display.

A measurement method of nozzle overlapping width, in a main scanning direction intersecting a conveying direction of a recording medium, in an inkjet recording apparatus including a plurality of heads each having a plurality of nozzles that eject ink, includes a first step (S120), a second step (S130), and a third step (S140). The first step (S120) includes forming an image for measurement on the recording medium, using image data including combination patterns of droplet sizes, different with respect to each of blocks extending along the main scanning direction. The second step (S130) includes selecting the block having uniform density along the main scanning direction, in the image for measurement. The third step (S140) includes determining the nozzle overlapping width using a droplet size ratio adopted to form the image for measurement, on a basis of a position of the selected block.

A droplet measurement system (DMS) is used in concern with an industrial printer used to fabricate a thin film layer of a flat panel electronic device. A clear tape serves as a printing substrate to receive droplets from hundreds of nozzles simultaneously, while an optics system photographs the deposited droplets through the tape (i.e., through a side opposite the printhead). This permits immediate image analysis of deposited droplets, for parameters such as per-nozzle volume, landing position and other characteristics, without having to substantially reposition the DMS or printhead. The tape can then be advanced and used for a new measurement. By providing such a high degree of concurrency, the described system permits rapid measurement and update of droplet parameters for printers that use hundreds or thousands of nozzles, to provide a real-time understanding of per-nozzle expected droplet parameters, in a manner that can be factored into print planning.

An information processing device performs processing of specifying a positional relationship between a first printing section and a second printing section based on image capturing data of a test image that is printed on a printing medium by the first printing section and the second printing section in each of which a plurality of printing elements are arranged. The test image includes a plurality of first lines which are printed by the first printing section so as to have printing positions different from each other in a line arrangement direction on the printing medium and a plurality of second lines which are printed by the second printing section so as to have printing positions different from each other in the line arrangement direction. The information processing device contains a printing coordinate acquisition section, a printing position acquisition section, and a positional shift amount calculation section.

A liquid discharge apparatus records dots of liquid on a medium by interlace recording. The liquid discharge apparatus includes a head, a mover, a tilt adjuster, and control circuitry. The head discharges the liquid from nozzles. The mover relatively moves the head and the medium in each of main-scanning and sub-scanning directions. The tilt adjuster changes a tilt of the head with respect to the medium. The control circuitry controls recording on the medium. The control circuitry causes the mover to relatively move the head and the medium in the main-scanning direction with the head tilted to at least a first angle or a second angle. An interval between adjacent nozzles in the sub-scanning direction is a first interval in a state where the tilt is the first angle. The interval is a second interval different from the first interval in a state where the tilt is the second angle.

A droplet deposition apparatus (1) comprising: a first head module (101A, 101B, 102A) and a second head module (101B, 102A, 102B) arranged in at least partially overlapping relationship, each head module having a plurality of nozzles in at least one nozzle array (A1, B1); and a storage (200) configured to store a table of determined best aligned nozzle pairs in an overlap region and corresponding skew angles (Θi) of at least one of the head modules relative to a datum of the droplet deposition apparatus and/or a corresponding positional offset of the second head module relative to the first head module; wherein, in the overlap region, nozzles of the first head module are arranged at a first nozzle pitch (P2) and nozzles of the second head module are arranged at a second nozzle itch (P3). Associated methods in respect of determining misalignment information in respect of such a droplet deposition apparatus, and determining one or more best aligned nozzle pairs in an overlap region between at least two head modules, are also provided.

A printing apparatus includes a printing head configured to eject ink onto a medium based on print data, a carriage that is mounted with the printing head and that is configured to reciprocate along a main scanning direction, a control unit configured to control the carriage and the printing head and execute a pass corresponding to ink ejection of the printing head along with movement of the carriage, and a colorimetric unit configured to measure density on the medium when the pass is completed.

The mover is configured to execute, among a first moving operation of moving a sheet-like medium and a second moving operation of moving the liquid ejection head, at least the first moving operation. The controller causes the liquid ejection head and the mover to alternately or simultaneously perform execution of the first moving operation and execution of ejection and second moving operations, and adjusts at least one selected from the group of an amount of liquid to be ejected, a time interval between the ejection operations when alternately performing execution of the first moving operation and execution of the ejection and second moving operations, and a moving speed of the medium when simultaneously executing the ejection operation and the first moving operation, according to medium information relating to curling of the medium.
