SYSTÈME ET PROCÉDÉ DE TRAITEMENT EN LIGNE DE PLAQUES D'IMPRESSION PHOTOPOLYMÈRES FLEXOGRAPHIQUES LAVABLES À L'EAU

摘要

The present invention proposes a system for processing water washable flexo photopolymer printing plates, the system (100) comprises a washing line (10) including one or more brushes (11) and a surface (12) essentially facing said brushes, and a guiding means (13) adapted to guide a water washable photopolymer printing plate (90) through the washing line (10) by pulling it from a vicinity of a downstream edge (91) thereof and automatically dragging such water washable photopolymer printing plate (90) on said surface (12). Said brushes (11) are adapted to contact onto a side of such water washable photopolymer printing plate (90) in a washing direction (WD) from the downstream edge (91) towards an upstream edge (92) thereof. The system further comprises one or more attachments (20) adapted to be annexed to the vicinity of the upstream edge (92) of a water washable photopolymer printing plate (90), the attachments being further adapted to exert friction onto the surface (12), said friction being greater than that between such water washable photopolymer printing plate (90) and said surface (12). The present invention further proposes a method of processing water washable flexo photopolymer printing plates (90) including stretching thereof between guiding means (13) and attachments (20) using extended friction obtained thereby.
