Abstract

The present invention is a method of producing a photographic support. The method includes providing a photographic paper and transporting the photographic paper through an atmospheric glow discharge zone, wherein the atmospheric glow discharge zone contains a gas with a dielectric strength which is less than air. The atmospheric glow discharge zone is subjected to an electric frequency between 40 kHz and 13.56 Mhz and an electric field such that an atmospheric glow discharge is formed; and the photographic paper is coated with a polymeric coating.
