FIELD: printing.
SUBSTANCE: invention relates to manufacture of packaging materials, in particular, to a method of manufacturing metallised label paper. The method includes the application of polymer varnish on base paper in at least two layers. The first varnish layer is applied by the method of direct printing, and the second layer by the method of reverse printing. Clamp of the paper to the plate shaft in the method of the reverse printing is carried out from the top with two shafts in which when lowering the lower line of the generatrix is located below the upper line of the generatrix of the plate cylinder, and the shafts are located on opposite sides of the plate cylinder. The diameter of the plate shaft applying the second layer of polymer varnish by the method of reverse printing is greater than the diameter of the shaft of the direct printing, which is 191-192 mm, by 8-9%. The viscosity of the varnish applied by the method of reverse printing is lower than the viscosity of the varnish applied by the method of direct printing. Then, on the layer of varnish a metal coating and a layer of varnish is applied, the mesh back side of the paper is moistened, and embossing of the paper is carried out.
EFFECT: invention provides improvement of quality of label paper by eliminating the formation of "ripples" on the surface of the varnish, and stability of the paper characteristics when change of ambient humidity.
