A method for printing on an item, that includes generating a scanned shape of the item, performing a lookup of the scanned shape in a shape database, making a determination that the scanned shape matches a saved shape in the shape database, and based on the determination, measuring an item rotation of the item, generating a transformed print image based on the item rotation, causing a printhead to print on the item using the transformed print image.

A printer and a method for printing of pages on a continuous media, such as labels, with any desired or practical spacing using fixed head printheads that have spacing limitations for printing pages on the continuous media. The printer can be configured to detect a top of form mark on the continuous media as it is moved through a media path in the printer and initiating printing of an image on an adjacent page or label at the position indicated by the top of form mark.

A printing system comprises a transport apparatus adapted to transport a flexible web along a process direction and first and second individually controllable ink jet imager units offset from one another along the process direction. Each of the first imager unit and the second imager unit includes a first portion operable to print on a first portion of the web and a second portion operable to print on the second portion of the web wherein each of the first portion and second portion of the first and second imager units is stationary along the process direction and the lateral direction.

In a printing method, at least one image of a substrate supported in a printing system is acquired. An actual position of a first alignment feature on the substrate in a frame of reference of the printing system is determined based on the at least one image. Expected positions of second alignment features on the substrate are determined based on the actual position of the first alignment feature. Actual positions of the second alignment features in the frame of reference of the printing system are determined based on the at least one image and the expected positions of the second alignment features. Target positions of print regions on the substrate are determined based on the actual positions of the second alignment features. Ejection of print material onto the substrate in the print regions is controlled based on the target positions of the print regions.

A liquid discharge apparatus includes a head, processing circuitry, and a memory. The head includes a plurality of nozzle rows in each of which a plurality of nozzles are arranged. The processing circuitry detects landing positions of the liquid discharged from the plurality of nozzle rows and corrects the landing positions of the liquid based on a result of detecting the landing positions of the liquid. The memory stores data related to a relation among the landing positions of the liquid. The processing circuitry detects landing positions of the liquid discharged from one representative nozzle row. The processing circuitry corrects landing positions of the liquid discharged from all of the plurality of nozzle rows based on a result of detecting the landing positions of the liquid discharged from the one representative nozzle row and the data related to the relation among the landing positions stored in the memory.

A processor identifies print defect locations where printing defects occur and a assigns different sensitivity values to different zones of a job image being prepared for printing by a printing engine. The processor changes the orientation of the job image to a revised orientation, relative to print media, to avoid locating one or more high-sensitivity zones of the job image in the print defect locations. The high-sensitivity zones are ones of the zones having a sensitivity value above a threshold sensitivity value. The printing engine prints the job image on the print media at the revised orientation.

A printing system comprises a transport apparatus adapted to transport a flexible web (24) along a process direction and first and second individually controllable inkjet imager units (44, 60, 70, 82) offset from one another along the process direction. Each of the first imager unit and the second imager unit includes a first portion (226) operable to print on a first portion of the web and a second portion (228) operable to print on the second portion of the web wherein each of the first portion and second portion of the first and second imager units is stationary along the process direction and the lateral direction.

The present disclosure provides a substrate treating apparatus capable of stably moving a substrate and discharging an ink at an accurate position. The substrate treating apparatus of the present disclosure comprises: a stage extending in a first direction and moving a substrate along the first direction; moving units disposed on both sides of the stage extending in the first direction, respectively, and configured to move the substrate in the first direction; and a control unit configured to align the substrate, wherein the moving unit includes a first gripper and a second gripper configured to adsorb one side and the other side of the substrate, respectively, after the first gripper adsorbs one side of the substrate, the control unit aligns the substrate, and after the substrate is aligned, the second gripper adsorbs the other side of the substrate and the substrate is moved in the first direction.
