The invention relates to a method and a device that permit the production of an optionally multi-colored film in a simple and cost-effective manner. In this method for the production of a film, toner is first applied to a transport belt with the use of at least one printing unit in such a manner that an essentially uninterrupted toner layer is formed on the transport belt. The toner on the transport belt is then heated with at least one first heat source to a temperature above a melting point of the toner and is subsequently cooled to below the melting point of the toner. Finally, the toner is removed from the transport belt as a cohesive material layer. The device comprises a transport belt, at least one printing unit arranged for applying a toner to the transport belt, and at least one heat source. Viewed in a direction of movement of the transport belt, the heat source is arranged downstream of the at least one printing unit in such a manner that said heat source is able to heat the toner present on the transport belt and that said heat source is suitable to heat the toner to a temperature above a melting point of said toner. |
