The traditional tinplate printing process has some obvious defects: high temperature baking is required, high energy consumption; harmful gas is produced, causing air pollution; it takes up a lot of space; printing efficiency is low.Developed countries mostly use UV printing technology, which has many advantages such as fast production speed, good product performance, quality optimization, environmental protection standards, reduced energy consumption, and less space.With reference to Japanese and German technology, combined with the actual situation of domestic iron printing equipment, after three years of development and experimentation, a UV light curing system for iron printing dedicated to supporting iron printing equipment has been developed to replace the traditional drying room drying equipment.
