Abstract

A printing equipment accessory, especially for making proof prints, with at least two rollers forming a roller nip, through which is passed at least one function component of a film from a supply roll, the film having an auxiliary component in addition to the function component, whereby the function component is transferable in the roller nip onto a base. Reuse of the auxiliary component of the film is simplified by such an accessory. The auxiliary component of the film forms a coreless roll.
