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.
