The rotogravure technique is one of the types of gravure printing. The printing frame here consists of a cylinder with an engraved image. During the engraving process, cavities are made with a diamond needle or through chemical etching. The printing ink is collected in the cavities and transferred to paper from there. This technique is usually used for highly efficient printing.
Polska Wytwórnia Papierów Wartościowych S.A. (Polish Security Printing Works) has been the producer of stamps for Poczta Polska for many years, it produces over half a billion items per year. The company’s portfolio includes, among others, scented stamps, triangular stamps, stamps with dry embossing, stamps with an overprint transferred by the means of unconventional inks and ground prints used for the production of personalized stamps.
