Abstract

An ejection condition adjustment apparatus includes a unit configured to set, in a case where a large head to be driven includes a plurality of small heads each having a number of orifices and the small heads are disposed adjacent to one another on the large head such that regions of the respective small heads where the orifices are provided partially overlap one another, a range of orifices to be used and an ejection timing for the individual small heads such that positional shifts between adjoining ones of patterns formed by the respective small heads are minimized.

Description

technical field [0001] The present invention relates to a technique for adjusting ejection conditions of a large head including a plurality of small heads each having an ejection hole for ejecting ink or other type of liquid. According to the embodiments of the present invention, there are provided an ejection condition adjusting device, a liquid ejecting device, and an ejection condition adjusting method and program. Background technique [0002] Hereinafter, several kinds of inkjet heads will be taken as examples to illustrate the related art. FIG. 1 is an external view of an exemplary nozzle head (hereinafter referred to as "small head") 1 in which a plurality of nozzle holes 3 are arranged in a row. [0003] FIG. 2 is an example row type spray head (hereinafter referred to as "big head") 5 in which a plurality of small heads 1 are arranged at staggered positions along the longitudinal direction of the large head 5 . In the case shown in FIG. 2 , the small heads 1 adjac...
