Printing apparatus and printing method

摘要

A printing apparatus which can form an image formation dot for printing an image defined as an object to be printed on a printing medium, the printing apparatus comprising a line head which includes a nozzle array arraying a plurality of nozzles, by moving at least one of a printing medium and the head, in a direction intersecting a direction relatively changing a position of the printing medium and the head and a control unit which performs a specific operation forming a flushing dot besides the image formation dot by discharging a liquid on the line head, wherein, when a specific condition increasing viscosity of the liquid is satisfied, the control unit performs the specific operation of discharging the liquid to the printing medium and the specific operation of discharging the liquid to a place other than the printing medium.

1. A printing apparatus which can form an image formation dot for printing an image defined as an object to be printed on a printing medium, the printing apparatus comprising:
a line head which includes a nozzle array arraying a plurality of nozzles, by moving at least one of a printing medium and the head, in a direction intersecting a direction relatively changing a position of the printing medium and the head; and a control unit which performs a specific operation forming a flushing dot besides the image formation dot by discharging a liquid on the line head, wherein, when a specific condition increasing viscosity of the liquid is satisfied, the control unit performs the specific operation of discharging the liquid to the printing medium and also performs the specific operation of discharging the liquid to a place other than the printing medium, and wherein, when the specific condition is not satisfied, the control unit performs the specific operation of discharging the liquid to the printing medium and does not perform the specific operation of discharging the liquid to a place other than the printing medium.
