Abstract
A method of producing watermark paper comprising forming a patterned wire by fixing and bonding a lace to a cloth wire for papermaking, fitting this patterned wire to a cylinder mould of a cylinder-vat machine or a dandy roll as a face wire, and making paper by using the cylinder mould or the dandy roll to which the patterned wire is fitted. This method can easily and economically produce watermark paper having a delicate and complicated lace pattern in excellent gradation.
