PRINTING APPARATUS AND PRINTING METHOD
First Claim
1. A printing apparatus for performing printing on a medium in an inkjet method, comprising:
- a head unit having a plurality of nozzles for ejecting ink drops onto the medium ;
a main scan driver configured to drive the head unit to perform main scan operations of ejecting ink drops from the nozzles while moving in a main scan direction which is predetermined; and
a controller configured to control operations of performing printing on the medium by controlling the main scan operations of the head unit and the main scan driver,wherein, when the main scan operations are performed, the controller performs control with respect to each area of the medium such that the head unit ejects ink drops of one selected color onto a plurality of first selection pixels selected on a basis of a first mask data item and a plurality of second selection pixels selected on a basis of a second mask data item different from the first mask data item in an arrangement of a plurality of pixels to be selected.

Abstract
With respect to a configuration for performing printing in an inkjet method, the disclosure implements a more appropriate configuration in which it is difficult for the quantity of printing to deteriorate. This configuration includes a head unit (12), a main scan driver (14), and a controller (20). When main scan operations are performed, the controller (20) performs control with respect to the same area on the medium (50) such that the head unit (12) ejects ink drops of one selected color onto a plurality of first selection pixels selected on the basis of a first mask data item and a plurality of second selection pixels selected on the basis of a second mask data item different from the first mask data item in the arrangement of a plurality of pixels to be selected.

10. A printing method of performing printing by ejecting ink drops from a head onto a predetermined area on a medium while moving the head in a main scan direction, comprising:
-
a step of ejecting ink drops of one selected color from the head onto pixels of the predetermined area of the medium selected on a basis of a first mask data item; and a step of ejecting ink drops of a same color as that of the ink drops associated with the first mask data item, from the head onto pixels of a same area as the predetermined area selected on a basis of a second mask data item different from the first mask data item.
