The samples shown here were printed with special glass ceramic inks containing frits. Using these inks means, you do not need to apply glaze first. The big advantage: glaze/frites will be placed just where needed, transparent areas stay free and transparent, streaks which will probably appear while glaze is melt will be avoided. On top there are ceramic inks available for firing/tempering temperatures at 850°. This type of ink is requested for decoration prints on ceramic objects either direct or by transfer if this parts will be cleaned in private dishwashersThe transfer is thereby a perfectly accepted step, in order also for e.g. decoration of enamel cooking pots, plates, cups, sinks, bathtubs, etc., as can be seen here in the example, to be able to use the digital printing.
Glass inks not just for glass and ceramicGlass inks even can be used for Carbon Fiber printing. Since inorganic pigments guarantee long living vivid colors, tempering the coated print for some minutes at about 400 °C will even make it scratch resistant allowing many other applications and usage.
Glass can be „decorated“ and printed in different ways.Decisive for the choice of the method is the requirement for the final product with respect to e.g. scratch resistance, acid resistance and light resistance or the safety requirements and the application area.Longier offers the right solution for all areas:•UV printing without pre-treatment for "normal applications"•UV printing with special pre-treatment for extreme loads but without special requirements. The prints are even dishwasher-proof.•Printing with ceramic inks for post-tempering at about 720°C to create safety glass (ESG)•Or print PVB or EVA for the subsequent laminating of the panes to achieve „laminated safety glass“ or laminated glass for roll or sheet materials for e.g. use in the automotive sector or where extended safety specifications are in place.
