METHOD FOR OBTAINING AND APPLYING A DIGITAL INK FOR PRINTING ON A PIECE OF GLASS HAVING A FUNCTIONAL FILM AND INK OBTAINED USING THE METHOD
The invention relates to a method for obtaining a digital ink for use on pieces of glass provided with a functional film or thin film, such that although the frit has been milled or ground for use as a digital ink, its ability to dissolve the functional film or thin film during application is not affected. The method comprises the steps of: dispersing the frit in an organic medium; carrying out a first wet-milling using zirconium-microsphere mills, to a particle size of 2 µm; using an in-line iron remover to remove iron particles; carrying out a thermal process to calcinate and remove all remaining contaminants; and, once the thermal process is finished, subjecting to a second wet-milling using zirconium-microsphere mills, to a particle size of 1-1.7 µm.
The invention relates to a glass-printing machine that prints in a continuous movement, which comprises: an input area (1) into the printing machine; a scanning unit (2) for determining the position, size and quality of the glass or other substrate; a print bridge (3); optionally, an output scanning unit (4) for inspecting the quality of printing on the glass (or any other substrate); and an output area (5), wherein the machine also comprises a single roller conveyor for conveying from the input area to the output area of the machine, passing through all stations of the printing machine, wherein the rollers are driven by a three-phase motor, the rollers being divided into multiple parallel tracks (6), with guide rails (7) of suction cups being disposed therebetween, wherein the suction cups run along each guide rail (7) independently of the suction cups of the other guide rails (7), are moved independently by means of a linear motor that moves linearly in a plane below the rollers and are synchronised with each other.
