Inkjet technology uses tiny ink droplets to facilitate direct printing without the device coming into contact with the printing surface. Because this technology supports non-contact printing, it can be applied to various media and is now being introduced into a wide range of fields from general to industrial. The simple structure that combines the inkjet print head with the scanning mechanism has the advantage of reducing equipment costs. In addition, since they do not require printing plates, inkjet printers have the advantage of saving print setup time compared with traditional printing systems that need to fix print blocks or plates, etc. (such as screen printing).

There are three working principles of the 3d automatic holographic master table machine, namely:

1. Printing principle: It refers to the fact that the 3d automatic holographic master table machine adopts piezoelectric inkjet printing technology. It does not come into direct contact with the material surface. Relying on the voltage inside the nozzle, the ink in the spray holes is sprayed onto the surface of the substrate.

2. Curing principle refers to the principle of ink drying and solidification in the 3d automatic holographic master table machine. This is completely different from the previous printing equipment that requires processes such as baking and sun-drying. It uses the ultraviolet rays emitted by led lights to react with the photocoagulant in the ink to achieve the drying of the ink. The advantage of doing this is that it reduces unnecessary equipment and personnel expenses, and at the same time improves production efficiency.

3. Positioning principle refers to how the 3d automatic holographic master table machine precisely controls the equipment to complete the printing patterns on different material volumes, heights and shapes. For the positioning of the X-axis, it mainly relies on the raster decoder to direct the device on how to print horizontally. On the Y-axis, the length of the printed material is mainly driven by the servo motor. In terms of height positioning, it mainly relies on the lifting function of the machine head. With these three positioning principles, uv printers have achieved the performance of precise positioning printing.
