Abstract: The invention relates to a coating unit (2) for transferring imaging or covering layers from a transfer film (5) to a printed material. The coating unit is flexible thus enabling the integrated production of complex printed material. In particular, overprinting of film coatings should be able to be carried out in a problem-free manner. One or several discharge devices (E, EI), which are connected to the film application module (FA), are used for modifying the surface tension of the transfer film (5) or the printed sheet in the rotary sheet printing machine ensuring that the printing and also the film-coated surfaces of the printed sheet are of high quality.

Abstract: The invention relates to a unit for cold film transfer in a printing press. In order to improve the transfer process, a control device is used to control the film transfer, said control device adjusting the color values and the coating parameters of the transferred films.

Abstract: For transferring an image-forming layer from a transfer foil a printing sheet, an adhesive layer is first applied to the sheet to be printed. The transfer foil provided with the image-forming layer is guided past the printing sheet under pressure, in a coating module (2), such that the image-forming layer adheres to the adhesive and an image is created. The present invention provides a foil transfer device that includes a substrate on the press cylinder that has a reduced adhesiveness relative to the transfer foil.

Abstract: A sheet-fed printing press having an inking unit with ink applicator rolls for supplying ink to a plate cylinder and a damping unit having a damping solution applicator roll for supplying damping solution to the plate cylinder. The ink applicator rolls and damping solution rolls each are movable between thrown on and off positions relative to the plate cylinder. A control device is provided for predetermining a number of de-inking sheets that can be imprinted with an ink image while the ink applicator rolls and damping solution applicator rolls are in a thrown off position without ink being supplied from the inking unit. The control device is carried out as a function of prepress data or inline measured data. The printing press may also include a lacquering unit which is operable in thrown on or off positions during passage of said predetermined number of de-inking sheets.

Abstract: To transfer a coating in image form from a transfer foil to a print sheet, adhesive is applied in the form of the image to said sheet. In a foil transfer module (2), the carrier foil with the coating in image form is then brought into contact with the print sheet using contact pressure, so that the coating adheres to the adhesive pints and an image is produced. To improve the function, simplify the device and increase the flexibility of the method, a transfer cylinder (3) is provided with a covering that has a variable cover thickness (25), in order to adapt the surface speed of the transfer cylinder (3).

Abstract: In a method for transferring layers from a carrier foil onto printed sheets, an imaging or covering layer is to be transferred from the carrier foil onto the printed sheet in an adhering manner in a sheet processing machine. A more flexible production method is provided in a sheet offset printing machine. To this end, each printed sheet is provided on at least one printed or unprinted first side with a foil coating. Each printed sheet is further turned before or after the coating in the sheet processing machine, and at least printed or coated on the side opposite of the foil coating, and provided with a film coating in a further coating device (2).

Abstract: The aim of the invention is to diversify film coating in a coating station for transferring image-providing layers from a transfer film onto a printing material. For this purpose, a film transfer module is arranged in a printing press for single-color or multicolor printing of printed sheets. One or more devices for producing a surface structure on the printing material are arranged in the printing press upstream of a film transfer module. A design from a film image and a printed image is partially or completely covered by applying layers. The additional layers serve for the protection, for drying and for producing optical effects.

Abstract: The invention relates to a sheet-fed printing press, having at least one offset printing unit, varnishing unit and/or flexographic printing unit for printing printed sheets with at least one printing image. The printing press has at least one inspection device for detecting and evaluating each printing image which is printed onto the printed sheets in each offset printing unit, varnishing unit or flexographic printing unit. The printing press also includes at least one inkjet printing device and/or laser printing device which is integrated into the sheet-fed printing press for printing printed sheets with at least one further printing image. Each further printing image which is printed onto the printed sheets by each inkjet printing device and/or laser printing device also can be detected and evaluated by each inspection device.

Abstract: An inking unit in a printing machine having an ink dispensing system comprising an inking roller and a form cylinder carrying at least one printing form. The inking roller transfers printing ink arriving thereon to at least one printing form positioned on the form cylinder. The printing ink is transferable from a respective printing form to print sheets moved between the form cylinder and an impression cylinder. The inking roller is also adjustable relative to the form cylinder. An engagement and/or disengagement of the inking roller relative to the form cylinder and/or an engagement and/or disengagement of a print blanket cylinder or form cylinder relative to the impression cylinder is performable such that print sheets become can be imprinted with a residual ink image by residual ink remaining on the plate cylinder or print blanket cylinder in a printing ON setting with the ink supply disengaged.

Abstract: For transferring a coating in the form of a desired image coating from a backing film to a printed sheet, an adhesive layer in the form of the desired image is applied to the printed sheet. The transfer foil comprising the image-type coating is rolled over the printed sheet using contact pressure in a coating unit (2), in such a way that the coating adheres to the adhesive sections, thus forming an image. To improve the flexibility of this application in a printing press, either the coating unit or the adhesive application unit (1) and the coating unit (2) are located in one or more coating modules of a printing press, thus producing a simple, compact film transfer module (F).

Abstract: A device for transferring an image-forming layer from a transfer film to a printing sheet, including an applicator unit for applying a coating of glue in the form of an image to the printing sheet; and a coating unit including an impression cylinder for guiding the printed sheet with the coating of glue facing away from the impression cylinder, and a pressure roller for guiding the transfer film with the image-forming layer facing away from the pressure roller. The impression cylinder and the pressure roller form a transfer gap therebetween so that the transfer film and the printing sheet are pressed against each other when guided through the transfer gap so that the image-forming layer remains adhered to the printing sheet in the area of the coating of glue and is lifted off from the transfer film after leaving the transfer gap. A process is also disclosed.
