Problems solved by technology

However, when exposure times are short, for example, for bottom exposure of thinner gauge boards, lamp start non-uniformity and stability become important, leading to difficulties in good exposure control, which in turn results in floor thickness and Difficulty in uniformity control

Abstract

A system and method for producing a flexographic relief image printing plate from a liquid photopolymer printing blank The system comprises producing the relief image printing plate, selected from the group consisting of a glass setting apparatus for setting a desired gauge of the relief image printing plate, an apparatus for controlling UV exposure of the printing plate during an exposure step, and / or an apparatus for automatically performing a masking exposure of the printing plate. A microcontroller is operatively connected to the apparatuses and includes software for controlling the apparatuses and for storing data relating to the apparatuses. A user interface is operatively connected to the microcontroller and to the apparatuses and comprises means for entering data into the storage and means for selecting information relating to the apparatuses of the platemaking system.

Description

technical field [0001] The present invention generally relates to improved methods and apparatus for making liquid flexographic printing elements. Background technique [0002] Flexographic printing is widely used in the manufacture of newspapers and decorative printing for packaging media. In order to meet the needs of fast, inexpensive processing and long-term printing throughput, many photosensitive printing plate structures have been developed. [0003] Photosensitive printing elements generally include a support layer, one or more photosensitive layers, an optional slip film release layer, and an optional protective cover sheet. The protective cover sheet is formed of plastic or any other removable material that protects the above-mentioned plate or photocurable printing element from damage until ready for use. The above-mentioned sliding film can be disposed between the protective cover sheet and the photocurable layer to avoid contamination of the above-mentioned bo...
