摘要： A tandem printing system that can achieve stable web conveyance, regardless of the configuration of a tandem printing system or the type of a web, by preventing malfunctions including a broken web that may occur when slack in a web occurs at the time the printing operation stops and the slack is then eliminated after the printing operation has started.By executing low-speed conveyance of web by a web feeding mechanism before the printing operation begins, slack W22a, W10a, and W15a in the web located downstream of the guide rollers, and the slacked web is accumulated in the air loop portion, thereby completing the standby for printing. At that time, the amount of web conveyance (accumulation) is saved. Then, high-speed printing operation begins, and when the amount of printing has reached the amount of web conveyance saved, high-speed conveyance by the web feeding mechanism begins.
