Isimat Presents Its New Uvitro Technology For Glass Container Decoration

Traditionally, ceramic enamels are used for screen printing of glass containers. These so-called thermoplastic enamels flow at a temperature of 60-90 deg C. They are printed with electrically heated screens and solidify immediately when printed on a cold glass container. However, after printing they have to be burned (fired) in a lehr at a temperature of 620 deg C and slowly brought back to room temperature for handling. The process can take several hours and is costly in both energy and capital investment. In order to find a solution, ISIMAT has recently developed and engineered a new UV ink system for glass containers called UVitro technology, which has the ability to replace the traditional ceramic enamel coating method.
