The appearance is bright and glossy, with a dense and smooth colloid surface. The colloid material and mandrel are firmly bonded. The roller dimensions are strictly controlled, with sizes being:There will be minimal variation under different temperature and humidity conditions. It can adapt to the high temperature and humidity environment in southern printing workshops and the severe northern climate.Cold and dry climatic conditions. The colloid used in polyurethane roller has sufficient surface viscosity, ensuring the roller performs well during the printing process.Transfer and ink-absorption properties, with excellent ink-acceptance, ensure high-quality printing.
