Abstract
There is provided a system or apparatus for washing out flexographic printing plates. The system is presented in two distinct embodiments or aspects. In one embodiment the system is provided with a large number of rotating brushes which are at least partly immersed in a liquid bath. The second embodiment is based on a flat brush with an eccentric suspension
Claims12
A system for treating printing plates with a liquid, comprising:
- a vessel containing the liquid for cleaning the printing plates;
- means for conveying the printing plates to be treated through the liquid;
- a structure rotatably supporting a plurality of brushes of substantially cylindrical shape and provided with sets of bristles attached to a substantially flat support of each brush, said brushes having their shafts orthogonal to the printing plates to be treated, said brushes submerged at least partially in the liquid,
- wherein at least half of the sets of bristles of said brushes are angled 50-85 degrees, such as 70-85 degrees, and more preferably 80-85 degrees, relative to said flat support.

A system for treating printing plates with a liquid, comprising:
- a vessel containing the liquid for cleaning the printing plates;
- means for conveying the printing plates to be treated through the liquid;
- a support structure supporting a plurality of sets of bristles attached to support structure, said bristles submerged at least partially in the liquid and arranged so that the bristles touches the printing plate to be treated;
- wherein
- at least half of the sets of bristles are angled 50-90 degrees, such as 50-85 degrees or 70-85 degrees, and more preferably 80-85 degrees relative to support structure, and—said support structure is eccentrically pivoted onto a support frame, so that it can be moved by a motor with an orbital motion along a plane parallel to the printing plate to be treated.
