The object of the present invention is to fix the thermoplastic ink in powder state used to print digital images by means of an electrographic laser motor on self-adhesive web media such as self-adhesive paper webs, self-adhesive film webs such as polypropylenes, polyethylenes, polyesters, and vinyls, with different thicknesses and finishes, allowing work to be stopped between one production batch and another and/or stops for self-calibration of the print motor without changing the self-adhesive media, preventing problems due to overheating of the printout. The apparatus according to the present invention makes it possible to enhance the fixed prints with a glossy, matt, or holographed finish, without the need for subsequent treatment and/or the use of chemical materials afterwards, offering greater flexibility and economy at work.
An apparatus for fixing digital images printed with thermoplastic ink or powder toner on self-adhesive material (A) on a reel (A′), with different thicknesses and finishes, the said apparatus used to print digital images by means of an electrographic laser print motor, characterised by the fact that the said apparatus comprises at least one hot roller (8) for fixing the toner and at least one unheated pressure roller (9), opposite the said hot roller (8), and at least one hot air conveying chamber (2) having a cusp-shaped outlet section slotted towards at least one confinement chamber (7) adjacent to an external surface portion XX′ of the said hot roller (8).
A method for fixing toner to self-adhesive material (A) made of either paper or plastic films with different thicknesses and finishes comprising the following steps:
