IMAGE FORMATION DEVICE, IMAGE FORMATION CONTROL METHOD AND IMAGE FORMATION CONTROL PROGRAM

摘要

PROBLEM TO BE SOLVED: To enable high quality image formation by preventing image deterioration with wrinkles, skew or the like of a medium to be recorded due to ununiformity of moisture distribution.SOLUTION: An ink jet recording device 1 forms an image by discharging ink of each color to roll paper P from a colored line head 31 consisting of line head units 31Bk, 31C, 31M, 31Y of each color in accordance with image data to detect the change in the roll paper P width direction before and after the image formation with a paper width detection sensor 4. The ink jet recording device 1 discharges transparent ink from a transparent line head unit 32 to a non-image formation region so that the paper width change of the roll paper P becomes uniform.
