Abstract: A device coats one or more panels, printed by a coating means, which applies particularly a varnish or a primer. The device utilizes a forme roller which can be brought into rolling contact with the print stock to be coated, in the region of a contact zone, in order to coat the print stock on a side of the print stock facing the forme roller, and also utilizes a feed device supplying the forme roller with coating medium, which interacts, in the region of at least one contact zone on the circumference of the forme roller, with the forme roller, in order to continuously apply the coating medium, which is to be applied to the print stock, to a shell surface of the forme roller to an application width.
