Talking about the Classification of Printing Light Sources

In the printing process, special light sources can be used for UV light curing of surface coatings, printing, paper packaging, decorative materials, printed tin cans, etc.; can also be used for non-silver salt film, diazonium salt film, film, resin plate, PS Edition printing, exposure and more. There are many special light source products, which are applied to different printing processes according to their respective parameters. Here we introduce three special light sources for plate making, printing, and light curing. Now let's go and enjoy them.

A: plate making light source

Common plate-making light sources are mainly divided into five categories. The first category is incandescent lamps, infrared lamps and halogen lamps; the second is mercury lamps; the third is metal halide lamps; the fourth is neon lamps; and the fifth is plate making lasers.

Second: print version of the light source

Frequently used copying light sources include: carbon lamps, high-pressure mercury lamps, xenon lamps, fluorescent lamps (cold lamps), and metal halide lamps.

Three: UV light curing light source

There are two types of light sources for UV-hardened materials: an electrode UV light source (ArcUVLamp), an electrodeless UV light source (Electrode-less UVLamp).

Electrode-type UV light source consists of a quartz tube, after evacuation, inject a certain amount of mercury or fill in some special materials. After placing one electrode at each end, seal the two ends of the electrode with ceramic insulated wires or directly with metal fittings. The power supply is connected.

The electrodeless UV light source consists of a quartz tube, which is evacuated and then filled with a certain amount of mercury or filled with special materials to seal it. There is no electrode in the lamp. UV light is generated by microwaves that excite mercury or special materials in the lamp.
