Printing device and printing method

摘要

A printing device, which prints an image on a recording medium using a printing head which has a nozzle row, where a plurality of nozzles are aligned in a first direction, for each color of ink, including: a printing control section which executes a plurality of cycles of a dot forming action, where dots are formed on the recording medium along a second direction which intersects with the first direction by discharging ink from the nozzles while the printing head is moved in the second direction, and a transport action, where the recording medium is relatively transported in the first direction with regard to the printing head after completion of the dot forming action.

1. A printing device, which prints an image on a recording medium using a printing head which has a nozzle row, where a plurality of nozzles are aligned in a first direction, for each color of ink, comprising:
a printing control section which executes a plurality of cycles of a dot forming action, where dots are formed on the recording medium along a second direction which intersects with the first direction by discharging ink from the nozzles while the printing head is moved in the second direction, and a transport action, where the recording medium is relatively transported in the first direction with regard to the printing head after completion of the dot forming action, wherein the printing control section is provided with a front position calculating section which calculates a front position of a dot region, which is able to be formed by the dot forming action in an N+1th (where N is an integer of one or more) cycle, for each nozzle row by a predetermined transport amount being added to the position of the dot region which is formed using the dot forming action of an Nth cycle, a skipping amount calculating section which calculates the size of blanking regions for each color from each front position which has been calculated to a portion where a dot row of a color which corresponds to the nozzle row is requested and calculates the smallest amount out of the sizes of the blank regions of each color which have been calculated as a skipping amount, and a transport amount determining section which determines a transport amount in the transport action in the Nth cycle by adding the skipping amount to the predetermined transport amount.
