Application: Ceramic and Enamel
Longier‘s Racer and Performer series of printers have been designed especially for printing porcelain and glass but are also perfect for printing enamel on e.g. metal sheets. Ceramic inks, which are fused to the carrier at temperatures of about 1,200 °C, allow many applications not possible for traditional organic inks. Whereas all flat objects can be printed directly you need to do transfer printing for all non flat objects like plates, cups, sinks or so. However, the process is quite simple and similar. Rather than print directly you print on special transfer paper be printed directly, but printing can also be done by transfer with a special transfer paper. Ceramic inks contain special ceramic pigments, however, for binding to the base plate, a glass layer so called glaze needs to be applied first. After printing the object will be put into an oven and be fired at about 1,200 °C.
However, it‘s not always suited applying glaze so other inks containing the glass pigments so called frits must be included. Those inks are available and perfectly suited for so called decoration printing and firing at temperatures of 720°C or 850°C. Please look for Performer series printer since these inks need a more sophisticated ink system and ink handling inside the printer.
Whether we talk about enameling art or practical application, plates up to 100 mm thickness (more on request) can be printed directly.   Ceramic prints are robust against scratching, acids, UV- light, ….. and can be used for versatile applications like front panels for electric devices, etc.
Digital printing on glass with ceramic inks has been possible for a long time more or less reserved for a company. Together with a world-leading manufacturer of ceramic inks, Longier has developed inks that can also be used on our printers and offer the same characteristics. The glass samples on the left were first pre- coated with Glaze and then printed with "normal" ceramic inks. This has the advantage that the printer has to be less complex.
