FIELD: methods and devices for marking.
SUBSTANCE: method involves short-term contact of the shell with the relief of cylindrical printing forms of printing machines, part of the surface of which is coated with a layer of a liquid composition containing water, a thickener and a solvent for the polymer material of the shell, followed by drying, heat treatment and shrinkage. Heat-shrinkable polymer film is used as shell.
EFFECT: invention provides improved performance of method for relief marking of shells.
