Abstract
The aim of the invention is to improve the supply of transfer foil in a coating module in which the image-forming layers of a transfer foil are transferred to a printing material. To achieve this, a partial pressing surface is located in the coating module for transferring the layers of the transfer foil. This permits targeted control of the foil feed. The transfer foil can be fed past a pressure cylinder in an approximately tangential manner and with a limited width.
Claims6
A method for coating a printing sheet in a sheet-fed printing machine comprising the steps of:
- coating an image area of the printing sheet with an adhesive pattern in an application unit;
- and
- guiding a transfer foil through a transfer gap in a coating module under pressure together with the printing sheet with a coated side of the carrier foil in contact with the printed sheet such that an image-forming layer of the transfer foil adheres to the printing sheet in the image area, the transfer gap being defined by an impression cylinder and a press cylinder, wherein the transfer foil is only pressed against the printing sheet in the image area.
