Deformed example 1

[0045] In the embodiment, the case where the multi-color printing system 100 is provided with four printing units of the first printing unit 10A, the second printing unit 10B, the third printing unit 10C, and the fourth printing unit 10D has been described; Here, it only needs to include two or more printing units.

Deformed example 2

[0047] The calculation method of the misregistration amount is not limited to the calculation method of the embodiment. Those skilled in the art can understand that the registration offset can also be calculated by other calculation methods. For example, the misregistration amount may be calculated using a captured image obtained by capturing a register mark.

Abstract

Provided is a technique capable of reducing an influence of a change in web conveying speed on misregistration. A multi-color printing system prints on a web with a plurality of plate cylinders. The multicolor printing system includes: a determining unit (55) for determining whether or not the conveying speed of the web is changing; a constrasting unit (57) for controlling a plurality of plate cylinders in accordance with the determination result by a determining unit (55), in order to avoid shifting of a printing pattern to be printed on the web by the plurality of plate cylinders.

Description

[0001] This application claims priority based on Japanese Patent Application No. 2016-102363 filed on May 23, 2016. The entire contents of this Japanese application are incorporated herein by reference. technical field [0002] The invention relates to a multi-color printing system and a control method. Background technique [0003] There is known a multi-color printing system in which a plurality of printing units are arranged along a conveying path of a web, and the printing plate cylinders installed in each printing unit are individually driven to rotate so as to sequentially print on the web. In a multi-color printing system, the registration mark printed on the roll material is detected, and the offset of the printing position (registration offset) generated between each printing plate cylinder is calculated according to the detection result, And control the drive motor of the plate cylinder to correct the registration offset. [0004] Patent Document 1: Japanese Pate...
