Impactless printing machine and method of electrographic printing

摘要

The invention relates to the printing of an image on a relatively thick dielectric layer. According to the invention, a liquid dielectric composition is applied by means of a device (3) having a continuous belt (1), and then it is dried (4) and uniformly discharged (7), before a printing head (8) forms a latent image. The image is then developed (9) and dried (11) before fixing (12). The dielectric layer (20) is then separated from a separation roller (19) and the belt (1) is cleaned. Preferably, the colour-changing agent (toner) used for the development is based on a resin belonging to the same family as the resin of the dielectric layer. Application to the manufacture of wallpaper and tiles for covering floors and walls. <IMAGE>
