A print processing portion causes a print device to execute printing of a print image based on print data in accordance with a first scanning amount detected when manual scanning is performed at a first time. A density complementation processing portion causes the print processing portion to execute reprinting in accordance with a second scanning amount detected when the manual scanning is performed at at least a second time. When the manual scanning is performed at at least the second time, the density complementation processing portion identifies density insufficient parts in the print image printed by the print device based on the scanning amount and an image read by an optical reading device. Furthermore, the density complementation processing portion causes the print processing portion to execute the reprinting for the density insufficient parts.

According to one example of the present invention there is provided a method of printing, with a printer, an image on a substrate, the printer comprising a substrate support. The method comprises obtaining an image to be printed, determining an offset position of a substrate positioned on the substrate support relative to a predetermined reference printing position, and controlling the printer to print the image to be printed at the determined offset position.

A printer comprising a printhead comprising a number of non-staggered nozzles and a processor communicatively coupled to the printhead, in which the processor executes computer usable program code to adjust the firing time of a number of nozzles within a group of nozzles by a portion of a full dot row. A method comprising, with a processor, adjusting the firing time of a number of nozzles within a group of nozzles of a printhead by a portion of a full dot row by delaying the firing of a subset of those nozzles by a full dot row, in which the nozzles of the printhead are not staggered.

The disclosed nanoimprinting method suppresses fluctuations in thickness of residual film and defects due to residual gas in a resist film, onto which a pattern of protrusions and recesses is transferred, in a nanoimprinting method that employs the ink jet method to coat a substrate with droplets of resist material. Droplets are coated onto a substrate such that the spaces between the droplets along an A direction which is substantially parallel to the direction of the lines of a linear pattern of protrusions and recesses are longer than the spaces between the droplets in a B direction which is substantially perpendicular to the A direction, in a nanoimprinting method that coats a substrate with the droplets of a resist material using the ink jet method.

A method of controlling a printer is disclosed, the printer including a number of print heads extending across a print zone, and each print head including at least one nozzle array extending in a direction of a print head axis. Each nozzle array comprises a center section of nozzles and side sections of nozzles, wherein the side sections of neighboring nozzle arrays overlap defining an overlap region and the center sections of the nozzle arrays define non-overlap regions. The method includes: printing a test pattern using at least two nozzle arrays, the test pattern comprising an interferential-type pattern printed by the side sections of the nozzle arrays in the overlap region and a reference pattern printed by the center sections of the nozzle arrays in the non-overlap regions; detecting characteristics of the printed test pattern; comparing the characteristics of the printed test pattern in the overlap region and in the non-overlap region; and deriving information concerning the alignment of nozzle arrays from the comparison

An inkjet printing device includes a stage part including a stage, an inkjet head part including at least one inkjet head that disposes an ink on the stage, the ink including dipoles and a solvent having the dipoles, a heat treatment device that removes the solvent, a first sensing part that measures a position of the ink disposed on the stage, a second sensing part that measures a position of the inkjet head, and a third sensing part that measures a position of each of the dipoles disposed on the stage. A dipole aligning method includes disposing an ink on a substrate, the ink including dipoles and a solvent having the dipoles, generating an electric field on the substrate and disposing the dipoles on the substrate by the electric field, removing the solvent, and measuring a position of each of the dipoles disposed on the substrate.

In one example, an apparatus is described, which includes a platen locating the print medium, at least one printhead for marking on the print medium, a carriage holding the at least one printhead, a sensor at least partially mounted to the carriage to measure a printhead-to-platen spacing (PPS) along scanning axis during scanning, and an integrated circuit including a dynamic compensation module and a PPS analysis module to delay firing of printing fluid drops from the at least one printhead to compensate platen defects based on the measured PPS.

Systems and methods are provided for seeding print defects and inspecting print jobs. One embodiment is a system that includes a print server. The print server includes an interface that receives a test print job, a memory that stores the test print job, and a print controller that determines a number of copies of the test print job to print, subdivides each sheetside image of the test print job into a number of distinct zones corresponding to the number of copies, assigns each of the zones to a different copy of the test print job, and for each copy of the test print job, and seeds a print defect into each sheetside image of the copy within a zone assigned to the copy.

A deposition device is described. The deposition device has a substrate support and a laser imaging system disposed to image a portion of a substrate positioned on the substrate support. The laser imaging system comprises a laser source and an imaging unit, and is coupled to a deposition assembly disposed across the substrate support.

An inkjet printing method, performed by an industrial inkjet system to form a decoration layer, includes the steps of, printing copies of a decorative image with a printing unit on a substrate by transmitting consecutive bitmap rows of the decorative image to a printing unit, measuring dimensional changes in the substrate while printing copies of the decorative image, and compensating the dimensional changes while printing copies of the decorative image by one of: skipping at least one bitmap row of the decorative image upon dimensional expansion, or reprinting at least one bitmap row of the decorative image on the substrate upon dimensional shrink.
