Washing device

Provided is a washing device that has a small device configuration, is excellent in maintainability, and further has a high productivity. The washing device performs development using a washing solution while transporting an imagewise exposed flexographic printing plate precursor. The washing device has a transporting unit that transports the flexographic printing plate precursor along a transport path having a curved transport passage and a linear transport passage, using a leader and a developing portion that performs development by removing an unexposed portion of the flexographic printing plate precursor. The transporting unit transports the flexographic printing plate precursor using a winding transmission method or transports the flexographic printing plate precursor using a method of winding a traction member provided at the leader.

SYSTEM AND METHOD FOR IN-LINE PROCESSING OF WATER WASHABLE FLEXO PHOTOPOLYMER PRINTING PLATES

A system for processing water washable flexo photopolymer printing plates, the system comprises a washing line including one or more brushes and a surface essentially facing said brushes, and a guiding means adapted to guide a water washable photopolymer printing plate through the washing line by pulling it from a vicinity of a downstream edge thereof and automatically dragging such water washable photopolymer printing plate on said surface. Said brushes are adapted to contact onto a side of such water washable photopolymer printing plate in a washing direction from the downstream edge towards an upstream edge thereof. The system further comprises one or more attachments adapted to be annexed to the vicinity of the upstream edge of a water washable photopolymer printing plate, the attachments being further adapted to exert friction onto the surface, said friction being greater than that between such water washable photopolymer printing plate and said surface.
