PATTERN PRINTING SYSTEM FOR PARALLELISM ADJUSTMENT, PRINTING DEVICE, PRINTING CONTROL DEVICE, PATTERN PRINTING METHOD FOR PARALLELISM ADJUSTMENT AND PATTERN PRINTING PROGRAM FOR PARALLELISM ADJUSTMENT

摘要

PROBLEM TO BE SOLVED: To be able to easily adjust a parallelism and to make it easy to judge whether the parallelism after the adjustment is proper or not.;SOLUTION: A printing pattern to adjust a parallelism is printed by controlling by a computer a printing device which can print a bidirectional print and can adjust a parallelism of a reciprocating movement direction of head to an ink jetting face of a printing medium. In this case, the controlling computer prints a pattern print wherein a jetting ink at going movement and a jetting ink at returning movement are alternately adhered along the reciprocating movement direction on the printing medium in the printing device. Here, if a parallelism of the reciprocating movement direction of the head to a jetted face of the printing medium is not kept, a roughness appears due to lapping both ink adhesion positions at border of the jetting inks at going movement and at returning movement. As these results, an improper parallelism can be recognized.;COPYRIGHT: (C)2002,JPO
