Abstract
At a Munich printing-works it was observed over a period of several years that the gelatin films used for preparing printing cylinders in fully air-conditioned rooms became unfit for use at random intervals due to coagulation. It was assumed that this damage was caused by electromagnetic environmental factors. The working area for sensitization of the gelatin films was therefore surrounded by a Faraday cage. Since then coagulation of the gelatin films has never occurred again.
