Abstract
A film transfer apparatus includes an application unit, a transfer unit downstream of the application unit, and at least one third unit for further processing a printing material with a transfer layer applied. In the prior art, if contact pressure is exerted on coated printing material again in a following nip, the adhesive layer under the transfer layer can be pressed out. A blanket can then be contaminated with adhesive, ink itself can be contaminated and parts of the transfer layer can be detached from the coated sheet. In order to avoid pressing out the adhesive, measured values in the transfer unit are compared with corresponding values in the third unit. At least one controlled variable in the units can then be readjusted on the basis of a difference, to at least reduce the quantity of adhesive squeezed out. A transfer method and a covering surface are also provided.
