Abstract

An apparatus (10) for chemically watermarking paper which comprises a nip roller 11; a first coater roller 12; a second coater roller 12; an impression cylinder roller 15; and a die cylinder roller 18 in the form of a rotary shell. The impression cylinder roller 15 acts as an impression cylinder roller for the watermarking apparatus and 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.
