INK-JET RECORDING DEVICE AND INK-JET RECORDING METHOD

摘要

An ink-jet recording device and method capable of recording a high-quality image with no conspicuous joint belt-like line formed along the border portions between bands each of which is formed by horizontal scannings by serial recording. A band having a width corresponding to a predetermined amount M of movement is formed by (n+1) recording scannings. The ink-jet recording device has a control unit (10) which allows a second group of nozzles (61) to perform recording when the (n+1)+1-th horizontal scanning and beyond are performed under the condition that the relations L=M×(n+1)+α and M>α are satisfied where L is the length of a row of the whole nozzles (61) of a recording head (6) and α is the length of a row of a second group of nozzles (61) and allocate recording data to each of the nozzles (61) so that the border in the region recorded by the horizontal scannings on the upstream side of the relative vertical scanning direction of the ink-jet head relative to the recording medium may be formed in an intermediate portion of the width of the band formed by the first to (n+1)-th horizontal scannings.
