US 2011/0032297 A1 · PRINTING METHOD, COMPUTER-READABLE MEDIUM, AND PRINTING APPARATUS

Abstract

A printing method etc. capable of suppressing degradation in image quality of border sections between regions respectively printed by a plurality of nozzle rows that eject ink droplets is achieved. The printing method includes a step of setting, when at least two print heads that move in a movement direction intersecting a carrying direction and that include a plurality of nozzle rows each including a plurality of nozzles arranged in the carrying direction are moved in the movement direction, one ejecting method, of among a plurality of ejecting methods in which the nozzles for actually ejecting ink droplets are appropriately changed between an upstream-side nozzle and a downstream-side nozzle, for each of a plurality of aligned nozzle sections that are arranged such that the downstream-side nozzle of one print head and the upstream-side nozzle of the other print head, of the nozzle rows provided in different print heads, are aligned in the movement direction; and a step of ejecting ink droplets from the aligned nozzle sections according to the one ejecting method that has been set.

Dependent claims

A printing apparatus that prints an image by ejecting ink from nozzles onto a medium that is transported in a transporting direction, the printing apparatus comprising:

a) a first print head, mounted on a carriage moving in a carriage movement direction during printing, provided with a nozzle row including nozzles which are arranged in a row along the transporting direction;
b) a second print head mounted on the carriage and provided with a nozzle row, a section of the nozzle row of the second print head overlapping a section of the nozzle row of the first print head to form a first aligned nozzle section;
c) a third print head mounted on the carriage and provided with a nozzle row, a section of the nozzle row of the third print head overlapping a section of the nozzle row of the second print head to form a second aligned nozzle section;
d) a memory that stores information about a number of nozzles in each of the first and second aligned nozzle sections;
and
e) a controller that controls a timing at which the ink is ejected from the first, second and third print heads based on the information about the number of nozzles in the each aligned nozzle section.
