If the reflector is not installed, about 80% of the UV light cannot reach the surface of the printed matter due to diffusion. Therefore, the UV lamp must be installed with a lamp cover to make the UV light reflect and concentrate on the surface of the printed matter. At the same time, it is also necessary to clean and maintain the reflector at any time. If the paper powder or spray powder is attached to the reflector, it will affect the reflection efficiency of the UV lamp. If the UV lamp is not used for a long time, the UV lamp cover should also be closed to prevent dust from entering.

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.
