Abstract
A device and method for transferring an image-forming layer from a transfer foil to a printing sheet is provided. The device includes an application unit for coating an image area of the printing sheet with an adhesive pattern that is colored and a coating module for transferring the image-forming layer from the transfer foil to the printing sheet. The image forming layer having a visual effect. The color of the adhesive pattern and the visual effect of the image-forming layer are configured such that the color of the adhesive pattern modifies the visual effect of the image forming layer when the image forming layer is applied to the printing sheet over the adhesive pattern.

A method for transferring a transparent image-forming layer from a transfer foil to a printing material in a sheet-fed printing machine comprising the steps of:
- coating an image area of the printing material with a colored adhesive in an application unit;
- guiding the transfer foil together with the printing material through a transfer gap in a coating module defined by an impression cylinder and a press cylinder, the transfer foil including a coating side having a transparent image-forming layer that is in contact with the printing material as the transfer foil and printing material are guided through the transfer gap such that the transparent image-forming layer is transferred to the image area of the printing material having the colored adhesive;
- said color of the adhesive underlying the transparent image forming layer modifying the appearance and visual effect of the entire transparent image-forming layer and the underlying adhesive as viewed through the transparent image-forming layer including an area of the transparent image forming layer where the adhesive completely underlies the transparent image forming layer when the transparent image forming layer is applied to the printing sheet over the adhesive pattern.
A method for transferring a semi-transparent image-forming layer from a transfer foil to a printing material in a sheet-fed printing machine comprising the steps of:
- coating an image area of the printing material with a colored adhesive in an application unit;
- guiding the transfer foil together with the printing material through a transfer gap in a coating module defined by an impression cylinder and a press cylinder, the transfer foil including a coating side having a semi-transparent image-forming layer that is in contact with the printing material as the transfer foil and printing material are guided through the transfer gap such that the semi-transparent image-forming layer is transferred to the image area of the printing material having the colored adhesive
- said color of the adhesive underlying the semi-transparent image forming layer modifying the appearance and visual effect of the entire semi-transparent image-forming layer and the underlying adhesive as viewed through the semi-transparent image-forming layer including an area of the semi-transparent image forming layer where the adhesive completely underlies the image forming layer when the semi-transparent image forming layer is applied to the printing sheet over the adhesive pattern.
