Our more than 100 years old tradition to produce high quality recording papers stands for our dedication and passion to serve you in the future.

Medical recording Papers
In the Thirties, the first medical recording papers were manufactured. The development began with ink-recorders. After ink-recorders, special papers, such as electrosensitive papers came into use. Early in the Fifties, high speed medical recording on paper became possible through the newly developed black paper base with a white thermosensitive wax cover.

This technology was constantly improved until the Seventies, when the first thermoreactive papers from the USA were introduced in Europe. Next to analog recording, alpha numeric recording was now possible. The recorded data is clearly to read, easy to record and at low cost.
