- Sep 01, 2017 -

Whether it is sheet-fed offset press or web offset press, you can use the following three kinds of registration detection and control system.

1, off-line registration detection and Open-loop control system

The operator may hand the registration mark Reader, to measure the position of the printed longitudinal and transverse registration mark, to adjust the relative parts of the printing plate cylinder by calculating the difference between the actual measurement data and the standard sample registration data.


2, on-line registration detection and Open-loop control system

During the printing process, the online registration detection and Open-loop control system of the printing press can automatically detect the position of the longitudinal and transverse registration mark, and when the difference between the test data and the standard sample registration data exceeds the range of the prescribed registration tolerance, the operator can adjust it according to the actual situation.


3, on-line registration detection and closed-loop control system

In the process of printing, the online registration detection and closed-loop control system installed on the printing press can automatically detect the position of the specimen longitudinal and transverse registration mark, the registration control system will be the actual detection data and the original set of registration data control, the system will be based on the size of the value of the range of tolerance, printing plate cylinder and other related parts of the adjustment.
