PRINTING CONTROL DEVICE AND PRINTING CONTROL METHOD

摘要

A sub-scanning distance in a case in which a gap between a recording head and a platen is broader than a second gap broader a first gap is lengthened more than a sub-scanning distance in a case in which the gap is the first gap more when sub-scanning which is sub-scanning of a longer distance than a pitch of nozzles of a nozzle line in a sub-scanning direction is performed. A sub-scanning distance in a case in which the record density of a print image of a specific print region is second record density higher than first record density may also be lengthened more than a sub-scanning distance in a case in which the record density is the first record density when the sub-scanning which is the sub-scanning of the longer distance than the pitch of the nozzles of the nozzle line in the sub-scanning direction is performed.

主权项

1. A printing control device for a printing unit that is capable of adjusting a gap g between a recording head having a nozzle line in which a plurality of nozzles are arranged in a different direction from a main scanning direction and a platen facing the recording head and supporting a print substrate and performs main scanning to move the recording head in the main scanning direction with respect to the print substrate and sub-scanning to move the print substrate in a sub-scanning direction relative to the recording head, the printing control device comprising:
a sub-scanning control unit that lengthens a sub-scanning distance in a case in which the gap g is a second gap broader than a first gap more than a sub-scanning distance in a case in which the gap g is the first gap when sub-scanning which is sub-scanning of the same printing scheme and is sub-scanning of a longer distance than a pitch of the nozzles of the nozzle line in the sub-scanning direction is performed.
