Digitally printed cork base plates

摘要

Production of digitally printed cork floor tiles comprises tempering a highly compressed cork substrate at above 150[deg] C for at least 5 hours, adhering and pressing an elastic damping layer, a high density fiberboard carrier plate and the cork substrate, grinding the substrate surface, applying an acrylic-based dispersion dye as barrier, drying the barrier at at least 45[deg] C for 1-5 minutes, applying a ultraviolet-hardening dye in a digital printing method and applying a sealing layer. An independent claim is also included for a cork floor tile produced by the above process. Preferred Features: The cork substrate is tempered under pressure in a pressing mold at 200[deg] C. The surface of the substrate is ground to a grain size of 200-300 after tempering.
