FIELD: production of laminated printed (stamp) web possessing compressibility and flexibility. SUBSTANCE: the preset compressibility characteristics of printed web 5 is ensured by the presence of intermediate layer 10 having, in fact, uniform distribution of pores 30 practically of same size. Layer 10 is located between layer of base 25 and working surface 15 of printed web. Pores 30 of compressible intermediate layer 10 are formed by dispersion of many high-melting microspheres in elastomer matrix. High-melting microspheres are made of thermoplastic resin or thermoplastic material. Elastomer matrix 35 containing microspheres is applied to upper surface of layer of base 25 and covered layer of base is subjected to vulcanization at temperature of approximately 80-150 C for 1-6 h to form compressible layer possessing practically uniform compressibility. All layers of web are joined to form assembly of reinforced compressible web. Final vulcanization results in production of laminated printed web. EFFECT: higher efficiency. 35 cl, 1 dwg
