Beschreibung
Zusammenfassung:	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 µm, carriers (30-50wt %) 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
