Modern gravure has a history of nearly one hundred years, and the technology is mature and stable, so that the gravure is a main printing mode for large-scale efficient printing production. With the development and application of gravure printing technology in recent 30 years, it was found that when printing materials such as PE films which are easy to stretch, a deviation correcting device must be provided on a gravure press because of uneven edge material of the PE film.
On intaglio printing presses, it is most common for the deviation correction device to be arranged between the traction unit and the first color intaglio printing unit; secondly, the deviation correcting device is arranged on the unwinding unit. In practical applications, the two methods have disadvantages:
