Flexographic printing presses, also known as flexographic printing machines, are letterpress printing devices that use rubber or soft, elastic polymer relief plates. They are widely used in packaging printing and are among the fastest-growing green printing equipment in the modern printing industry. The following are its core basic characteristics:
Core Technical Features
Plate and Inking System: Uses flexible polymer resin plates, resulting in low plate-making costs and short cycles. Employs a short ink path inking system using anilox rollers, which is simple in structure and facilitates precise ink control. The anilox roller line count has increased from 360-440 lines/inch in the early days to 800 lines/inch or even higher, enabling higher printing precision.
Ink Characteristics: Primarily uses water-based or UV inks, which are low-VOCs or VOC-free environmentally friendly inks. Pollution is far lower than traditional oil-based inks, meeting green production standards and particularly suitable for the safety requirements of food and pharmaceutical packaging.
Printing pressure adaptation: Zero or light pressure printing will not damage the substrate, suitable for materials such as corrugated paper that cannot withstand high pressure.
