Iron box proofing is a necessary way to achieve the predetermined process design function for product quality. Tin Box proofing is also a process method to check whether the printing plate manufacturing conforms to the printing practice function.
It can be said that Tinplate Box proofing is a bridge to communicate the connection between plate making quality and practical printing conditions. In particular, some precision products, with some special processes in the price of iron box proofing, must go through iron box proofing to achieve better printing quality.
If production is carried out blindly without iron box proofing, printing quality problems may occur simply, and even serious economic losses may occur. The basic requirement for the quality control of the iron box proofing is to check whether the printing function of the printing plate in practical production and the sample of the iron box sample can reach the basic common.
This intention requires th…
