Methods of printing calibration patterns, calibration methods, and printers
摘要:
A calibration-pattern printing method in a page-wide array printer having an array of print nozzles extending in a transverse direction of the printer comprises printing a respective calibration pattern portion on a substrate by at least one first portion of the nozzle array, changing the relative position of the nozzle array and substrate in the transverse direction then printing a respective further calibration pattern portion on the substrate by the at least one first portion of the nozzle array so that a given first nozzle-array portion prints a calibration pattern portion and further calibration pattern portion that are at least partially aligned with each other in the longitudinal direction and join up in the transverse direction to form an enlarged calibration pattern portion.
