Offset is usually used for flexographic printing. Due to its soft material, it is widely used in direct printing of corrugated cardboard. The main materials of the rubber sheet are natural rubber and synthetic rubber. Plate-making methods include manual engraving, laser engraving and plate-making. When using rubber sheets, pay attention to their printability. For example, considering the ink's ink affinity, ink transfer, coverage, and reproducibility, printing with water-based ink on natural rubber plates is better than synthetic rubber plates. Butyl rubber sheet is more suitable for solvent-based ink. Solvent-based inks should be avoided as much as possible to prevent the printing plate from being damaged by solvent corrosion. The rubber sheet can not only print the substrate with rough surface, but also print on the harder material, and has higher printing resistance. However, it is easily deformed, so it is not suitable for printing high-precision products.
