Blue4est ^® - The Blue thermal paper from the black forest

The eco-friendly thermal paper from Koehler

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.

Why the Name Blue4est®?

On some days, the hills of the Black Forest take on a peculiar, shimmering blue color – which is just as unmistakable and unique as the color of our new Blue4est® thermal paper.

It is this proximity to nature which helps us come up with new products so often – just like the world’s first sustainable thermal paper, Blue4est®.
