Abstract
A printing and peeling arrangement comprises an impression drum for supporting a print medium during application of a printing image thereto, and one or more rotating vacuum fingers for applying vacuum via suction caps to the print medium to peel the print medium from the impression drum after printing. The vacuum finger is mounted for radial motion towards the impression drum and thereby avoids impact damage onto the print medium from the edges of the suction caps that results from a purely rotational approach to the drum.
