Abstract: A method for applying a coating to a surface of a material while using electrophotography. According to this invention, a supporting material provided with a photoconductive layer has an electrostatic charge pattern, a coating material is applied to the supporting material with the aid of electrostatic forces, and the coating material is applied to the subject to be coated. In order to produce high-quality surface coatings, according to this invention, at least the duromer constituents including a resin and a hardener are applied, together or in succession, as a coating material to the supporting material.

Abstract: The device for applying decorations and characters on glass, glass ceramic or ceramic products includes an image roller (5) provided with an electrostatically chargeable photoconductive layer; a photo-exposure assembly (6) for generating an electrostatic charge image corresponding to at least one of decorations and characters to be applied; a supply container (8) for a toner with a device (8a) for developing the electrostatic charge image with the toner; a dimensionally stable transfer roller (7) for receiving the toner image, which is in direct contact with the image roller on one side and with the product (2) on its other side; at least two coronas (9, 10) including a first corona (9) arranged on the transfer roller (7) and a second corona (10) arranged under the product near the transfer roller (7) and a heater for burning the toner image onto the product, after electrostatically transferring the toner image to the product by means of the coronas.

Abstract: A device for printing on paper or plate-shaped materials, such as plates made of glass, ceramic, glass-ceramic or plastic materials, having a transport device for the plates to be printed and an electrostatic, in particular an electrographic, printing device arranged above it. With the printing process of this invention, in an efficient manner, a conveying and centering unit of a screen-printing device is combined as a transport device with the electrostatic, in particular the electrographic, printing device, which is compatible with the upper unit of the screen-printing device.

Abstract: The method of making a design and/or sign on glass, glass-ceramic and ceramic articles using a transfer agent includes providing a band-shaped carrier coated with a transfer agent; periodically advancing the band-shaped carrier coated with the transfer agent past a printing station; periodically printing the design and/or sign to be applied on the transfer-agent-coated band-shaped carrier with a heat-resistant toner to form respective printed toner images in succession on the band-shaped carrier in the printing station and registering reliably and periodically transferring the respective printed toner images to corresponding glass, glass-ceramic or ceramic articles by releasing the transfer agent from the band-shaped carrier.

Abstract: The invention relates to a process for manufacturing decorated ceramic and glass articles according to which a ceramic dye composition, including fine particles which comprise ceramic pigments and binding medium resin(s) as well as possible further additives, is applied by means of an electrophotographic reproduction process onto a transfer means, for example paper coated with gum arabic, the transfer means coated with the ceramic dye composition is applied onto the ceramic or glass article, and after removal of the transfer means, the ceramic dye composition is combined with the ceramic or glass article by baking. The invention also includes decorative ceramic or glass articles obtainable by means of the above process and a ceramic dye composition of the type mentioned above.
