Abstract: A machine for digital printing of glass sheets on their entire surface, including their border, comprising a printing table (1), a printing carriage (2) that travels along the printing table (1) on a number of travel guides (3), and a printing bridge (4) associated with the printing carriage (2) on which printing modules or heads (5) travel, characterized in that it has a head controller (6) that manages up to four encoders, which allows four simultaneous printing modes: Modality 1 along the X axis in single pass. Modality 2 along the Y axis in single pass. Modality 3 along the X axis in multipass. Modality 4 along the Y axis in multipass.

Abstract: Ceramic inkjet inks for non-porous substrates (such as glass, metals) whereby the viscosity of the inks at the jetting temperature of 33-50° C. is 8-20 mPa·s and increase substantially to more than a factor of 5 (greater than 100 mPa·s) after landing on the substrate. The invention also relates to processing/formulating steps and tuning of the bulk and dynamic properties suitable for (i) inkjet printing in the printhead channel and (ii) desirable high viscosity after landing on the glass substrate. The ink comprises: Glass Frit composition which is in the form of particles having a volume particle size distribution Dv90 of less than 1.5 ?m, carriers (30-50 wt %) and additives (0-10%). The ceramic ink mitigate ink splattering, spreading during and after landing, eliminate/reduce image defects because of dust contaminations from the environment on wet inks after printing.

Abstract: Glass printing machine with continuous glass transport comprising a loading station (1), viewing means (2) or a mechanical positioning system, a printing bridge (3), and an unloading station (4), where the machine comprises an upper level (9) arranged above a lower level (10), with a series of carriages (11) running continuously driven by linear motors (6) in one direction on the upper level (9) and in the opposite direction on the lower level (10); to achieve this change of direction, a first vertical drive (7) in the loading station (1) lifts the carriages (11) from the lower level (10) to the upper level (9) and a second vertical drive (8) in the unloading station (4) lowers the carriages (11) from the upper level (9) to the lower level (10). Achieving a machine with a precision of less than 0.1 mm that can be used for large loads.
