The sheet fed offset press is a lithographic printing machine, which is used to print high-grade commercial prints and packaging prints. It is the mainstream of modern paper printing. Due to its strong corrosivity, UV offset printing ink may cause ordinary printing ink rollers and blanket to expand, affecting the stability of printing pressure. In serious cases, it may also cause peeling or surface fragmentation. Therefore, UV offset printing has very high requirements for cots and blanket. The selection of ink rollers and blanket must be compatible with UV offset printing ink.
