The type that we sell are ALL placed on the counterpressure roll with the perforating teeth directed towards the rubber blanket. On this page you can find the original Per-F-Off-Set. Of this brand you have two different types. The classic Per-F-Off-Set and the more modern Per-F-Off-Set Plus. The classic Per-F-Off-Set is placed on the counter pressure roll and used in combination with an old rubber blanket. The more modern Per-F-Off-Set Plus also uses a thin counter plate that is placed on a compressible rubber blanket. One of the benefits of the second system is that the printed documents stay flat after perforation.
Below you can find the available types of perforating strips. For your information there are also creasing and cutting strips available for offset presses.
