Ceramic Decal Printing
Ceramic Decal Printing is a typical screen printing application whereby many solid colours are printed in very close registration. The print process is relative slow (max. 1600 iph) and due to the use of solvent based inks, often the screen has to be inspected. For this reason, the 4-post cylinder press SPS® VITESSA SL1+ is preferred. The slow drying ceramic inks require extreme long drying time. In addition, the transfer paper is hygroscopic and very sensible for humidity / temperature changes. Typically, long time Wicket Dryers are used in very long configurations.
The introduction of UV curable ceramic inks has had positive effect on printing speed and efficiency, however the use is limited to standard colours (no precious metal inks). SPS® introduced a special UV curing unit for this industry SPS® TURBOSTAR CER. This unit is equipped with a special doped UV lamp and, in order to prevent any material shrinkage has extreme efficient substrate cooling (air condition).
SPS® has over 1.000 units installed within the ceramic decal printing industry and is known for its reliability and close tolerance printing.
