Abstract

An apparatus (10) for chemically watermarking paper which comprises a nip roller (11); a first coater roller (12); a second coater roller (13); an impression cylinder roller (15); and a die cylinder roller (16) in the form of a rotary shell (18). The impression cylinder roller (15) acts as an impression cylinder roller for the watermarking apparatus of a printing means so that paper, preferably in discrete, may first be printed and then watermarked or vice versa in an essentially single step operation.
