Abstract

Disclosed is a control method for a digital ink-jet printing device to carry out multicolour ink-jet printing on an intermittent rotary printing device. The method includes the following steps: judging whether the current page is the first page; if yes, calculating an image length of the current page which needs to be printed, by subtracting the distance between an imaging components group and a reference from the page length, wherein the reference is the foremost printed imaging components group in the direction of the movement of a printed body, and acquiring the length of the current page as the image data of the calculated length after delaying the distance; if no, acquiring the unprinted length of the previous page as the image data of the distance, and the length of the current page as the image data of the calculated length. Accordingly, a control system is disclosed. The method and the system combine digital ink-jet printing technology with traditional printing technology, thus not only preserving the production efficiency of traditional printing but also greatly improving the utilization ratio of dielectric materials.
