Inkjet printer having switched firing of adjacent nozzles applying common color

摘要

A printing system includes a printhead having adjacent inkjet nozzles for dispensing a common colored ink and a controller adapted to direct firing of the adjacent inkjet nozzles so that adjacent local areas using the common colored ink are printed on a printing medium with alternate firings of the adjacent inkjet nozzles.

主权项

1. A printing system comprising:
an array of nozzles forming a printhead including a first inkjet nozzle and a second inkjet nozzle, aligned in a column direction, that comprise a nozzle pair, wherein the nozzle pair is arranged such that the second inkjet nozzle is the closest inkjet nozzle to the first inkjet nozzle in the column direction and the first inkjet nozzle and the second inkjet nozzle are configured to dispense a common colored ink; wherein the image data is such that the first inkjet nozzle and the second inkjet nozzle are arranged in a logical pair for a local region of the image, wherein the length of the local region in the column direction is less than the length of the nozzle array that forms the printhead; a controller configured to implement a printing process comprising: receiving the image data, and alternating an activation of the first inkjet nozzle and the second inkjet nozzle with respect to the local region such that both the first inkjet nozzle and the second inkjet nozzle are activated to print the image date within the local region during the printing process.
