Printing materials will affect the printing process: For example, how the ink is transferred to the substrate surface, how coated paper standard ink status on the substrate surface, the ink drying or surface absorption, the press operator to register control such a system. Common substrates coated paper plant have applied, non-coated paper coated paper bags, cardboard, food packaging, mendelevium foil and paper. It not commonly used cellophane coated paper, polyurethane and fabric. Gravure proofing is generally carried out online, sometimes with proofer. Gravure generally used for high-speed printing of high-quality multicolor Long live parts. It is used Roller Roller called intaglio These are generally iron, copper and a photosensitive layer. After the image area on the plate on behalf of small grooves made of chrome needed. But, really it is called composites or coated paper. With the 1960s a new generation of high strength and high modulus fibers - boron fibers, carbon fibers and high-strength organic fibers - the advent of composite materials into a new era. Boron fibers, carbon fibers and high-strength organic fibers as reinforcement of the resin matrix composites, and the subsequent emergence of refractory metal matrix, ceramic matrix and carbon-carbon composite material is referred to as the advanced composite materials. Although it is only 30 years old, but it has made remarkable progress.
