THERMAL TECHNOLOGY

THE STRUCTURE OF BLUE4EST® THERMAL PAPER

PHYSICS NOW WORKS INSTEAD OF CHEMISTRY

Blue4est® is the innovative thermal paper from Koehler. It is guaranteed to be free of chemical developers and can easily be used in any
conventional thermal printer. Instead of a chemical reaction to heat, the emergence of text on our new Blue4est® thermal paper is a purely physical reaction. The paper’s opaque functional layer turns transparent due to the effects of heat, and the black layer beneath it is revealed. Optionally, Blue4est® Pro features an additional protective layer that protects the paper from mechanical damage for use as label stock.
