PAGE-WIDE ARRAY PRINTING

摘要

A method in a page-wide array printing apparatus comprising at least first and second printing dies that overlap in a page width direction comprises the steps of calibrating the printing apparatus in a media advance direction to a higher resolution than the page width direction, the media advance direction being perpendicular to the page width direction, and using printing masks to control the operation of a plurality of nozzles in an overlap area between the first and second printing dies to reduce any visible defects caused by dot placement errors in the page width direction.
