| 摘要 |
<P>PROBLEM TO BE SOLVED: To solve such a problem that a beading is generated to degrade an image quality when an image is formed on a coated sheet for commercial and publishing printing. <P>SOLUTION: The line-type liquid discharge head 400 has a plurality of nozzle arrays 402A and 402B, each array having a plurality of nozzles 401 for discharging droplets, and the nozzles in the nozzle array 402A, and the nozzles 401 in the nozzle array 402B are staggeringly arranged. All the nozzles in the respective nozzle arrays 402A and 402B are used to provide a required resolution in a paper width direction. The distance L1 between the nozzles in the respective nozzle arrays 402A and 402B is set to be L1=T1×V1, where T1 is a liquid transfer amount impregnating time to a standard sheet, and V1 is a sheet conveying speed. <P>COPYRIGHT: (C)2008,JPO&INPIT |
