A flexible anti-marking system (450) for use on a printing press transfer cylinder (200) is resilient to compressive forces. The system includes an outer flexible substrate layer having a textured surface (110) protruding from a first side for supporting the freshly printed sheet material. The system further includes an inner flexible material (120) that is resilient to compressive forces having an outer surface disposed in contact with the back side of the outer flexible substrate layer and an inner surface for contacting the transfer cylinder. A stiffening strip is mechanically fastened to a longitudinal edge (350) portion, whereby the anti-marking system includes a stiffened longitudinal edge (333) for fixturing to the transfer cylinder, the stiffened longitudinal edge comprising the stiffening strip and the longitudinal edge portion of the outer flexible substrate.
L'invention concerne un système antimarquage flexible pour utilisation sur un cylindre de transfert de presse d'impression résilient aux forces de compression. Le système comporte une couche de substrat flexible externe présentant une surface texturée faisant saillie d'un premier côté permettant de supporter le matériau en feuille fraîchement imprimé. Le système comporte en outre un matériau flexible interne qui est résilient aux forces de compression présentant une surface externe disposée au contact du dos de la couche de substrat flexible externe et une surface interne afin de toucher le cylindre de transfert. Une bande raidisseuse est fixée mécaniquement à une partie de bord longitudinal, tandis que le système antimarquage contient un bord longitudinal raidi permettant une fixation au cylindre de transfert, le bord longitudinal raidi comprenant la bande raidisseuse et la partie de bord longitudinal du substrat flexible externe.
