FIELD: printing industry.
SUBSTANCE: invention relates to the field of printing industry. The method to make counterfeit-proof papers includes a stage of compaction of counterfeit-proof papers surface by application of a protective pattern onto the surface of the counterfeit-proof paper, besides, compaction includes printing counterfeit-proof papers by method of metallography printing. A mould of metallography printing is used with engraved areas, such that at least 80% of the whole surface area of each counterfeit-proof paper are coated with a combination of convex patterns of metallography printing and flat patterns of metallography printing. Also machines of metallography printing are described to realise the specified method.
EFFECT: group of inventions makes it possible to improve quality of secured papers.
