The first is the printing principle
It refers to the uv printer uses piezoelectric inkjet printing technology, does not directly contact with the material surface, rely on the voltage of the nozzle, the ink in the jet hole to the surface of the substrate. This involves how to precisely control hundreds of sprinkler head software control program, because this belongs to the core technology, can only import foreign sprinkler head, the domestic has not been developed and produced.

The second is curing principle( it uses the LED lamp emits ultraviolet light and ink in the light coagulant to reflect, to achieve ink drying.):
It refers to the uv printer ink drying, solidification principle. This is completely different from the previous printing equipment that requires baking, drying and other processes. The ultraviolet light emitted by the led lamp reflects with the light solidifying agent in the ink to dry the ink. The advantage of doing this is to reduce unnecessary equipment and personnel costs, but also improve production efficiency.

The third is positioning principle
It refers to how the uv printer accurately controls the device to complete printing patterns on different material sizes, heights and shapes. In the X-axis positioning, mainly rely on the grating decoder, to direct how the device horizontal printing; Up and down the Y-axis, mainly depending on the servo motor drive, printing material length; In the height of the positioning, mainly depends on the lifting function of the nose; With these three positioning principles, uv printer to achieve accurate positioning printing performance.
