For the first time, Ulrich Etiketten presents thermochrome inks which react on heat/warmth. The colour disappears or changes the colour as soon as the set-point temperature is exceeded. Concrete one part of the printing layout will have thermochrome ink. Exceeds the set-point temperature for a few degrees Celsius, the ink will change to colourless or transparent. Reverse thermochrome inks may be used in different ways in UV-offset, UV-flexo, UV-screen or UV-letterpress: as a kind of security feature, to verify secure storage, for advertising ideas, as copy protection, and so on.
Luminescent means the glowing of a substrate. Often the luminescent will be shown with UV-light – think about “bright” objects in discos or in dark rooms. As advertising impact, security element or attendance check of labels, luminescent varnishes will be used in all printing techniques.
