IMAGE DATA CREATION DEVICE, IMAGE DATA CREATION METHOD AND INK-JET SYSTEM

摘要

A host PC that creates image data used in an ink-jet printer capable of landing ink with a multi-pass method includes an image data creation means that creates the image data so that the ink jet printer forms an image with a halftone dot which is configured so that a relationship between a pass number and a dot pitch in a vertical scanning direction of an ink-jet head does not become an integral multiple relationship when the pass number is odd number, and a dot pitch does not become even number when the pass number is even number.
