Exposure machine for pad printer printing

This series of exposing unit is capable of exposing steel plates and polymer  plates. Here are some characteristics:

1. Excellent outlook with strong and light machine body. Users’ eyes and skin are protected by the closed metal case in preventing leakage of UV light.
2. Once pumped to vacuum. The whole process of exposing can be finished automatically. Easy to use and able to increase productivity at the same time.

Instruction:

Solar plate is made up of three layers:

1. A steel or plastic backing plate
2. A light sensitive polymer that will form the empression, this is the layer that hardens where it is exposed to UV light.
3. A cover film. This protects the plate and is removed before exposure.

The exposure time is different according to environment and operational way, mainly around 3 minutes is OK.

Brief introduction of process:

• Remove the cover film.
• The artwork , on overhead transparency film is placed on the top of the plate. During exposure, the black areas in the artwork block out the UV light and the plate underneath will remain soft, the clear areas will let UV light through and will harden the plate below.
• Scrub the plate in warm water , washes away the soft parts of the plate.
• Dry the plate and post-expose.
