UV printing, first uv printing can't see light because it is UV curing. The principle of the UV flatbed printer is actually the principle of inkjet. The UV ink is directly sprayed onto the panel through the nozzle. Cured by LED lights. Just hit it. More convenient. The unevenness is the relief effect. Because UV ink is a hard ink, the intensity of the relief effect can also be adjusted. Weak solvent inks can not be embossed.
uv flatbed printer uv means one: uv ink
Different from previous water-based inks, textile inks, oil-based inks, and solvent-based inks, the new generation of equipment uses uv ink. uv ink itself is a solvent-based and oil-based ink. It is a chemical ink with Slightly corrosive, so in daily use, try to avoid contact with the body. What needs to be understood here is that uv ink is divided into three grades, one is made in China, and the price is below 500; the other is produced by the original nozzle, the price is 500-1000; the other is high-grade imported, the price is 1000- Between 3000.
uv flatbed printer uv meaning two: curing principle
The curing method uses an internal cooling and solidification principle in which the odor is not generated, heat is not generated, and bubbles are not generated in a very short period of time. This is mainly determined by the photosensitizer present in the uv ink. When the photosensitizer is combined with ultraviolet light, the inside will be condensed and dried at a very high speed to achieve the curing effect. Usually the domestic curing lamp has a wavelength between 35 and 46, depending on the manufacturer. The difference is from the mercury lamp. The heat is low, the material will not be baked, no pollution, no mercury leakage, and environmental pollution.
uv flatbed printer uv meaning three: printing method
Direct piezoelectric inkjet printing, the nozzle is inkjet printed between 0.5cm and 1cm from the material, and the uv ink is directly sprayed on the surface of the material, and then irradiated through the LED lamps on both sides of the nozzle. Drying of the ink can be achieved.
