The difference between flatbed printers and ordinary inkjet printers lies in that the products produced by 3d automatic hologram master tables supply dry immediately under the irradiation of UV lamps. UV refers to ultraviolet rays. So, what is UV ink? In fact, uv ink refers to the ink that, under the irradiation of ultraviolet light, uses ultraviolet light of different wavelengths and energies to polymerize the monomers in the ink binder into polymers, thereby forming a film and drying the ink. UV ink also belongs to ink. As ink, they must have bright colors (except in special circumstances), good printable adaptability, and an appropriate curing and drying rate. It also has good adhesion and features wear resistance, corrosion resistance, weather resistance and other properties. UV ink is generally used in the casings of the electronics industry.

UV ink is mainly composed of oil, so the phenomenon of ink not drying or peeling off often occurs. So, what exactly is the cause?

Different types of materials, different ink layer thicknesses and different printed graphics have different requirements for UV curing equipment and devices. On the printing press, the power of UV curing, the printing speed and the thickness of the ink layer can be adjusted. If the operator fails to handle the relationship among them properly, it will affect the effect of UV curing.

2. The power of the UV lamp is insufficient

All UV lamps have an effective service life (generally 800 to 1000 hours). When the usage time of a UV lamp exceeds its service life, although the UV lamp can still work, its power has dropped significantly. However, due to cost considerations, label printing enterprises do not replace UV lamps that have exceeded their service life in a timely manner.

3. The ink layer is too thick, the paper feeding speed is too fast or the UV light exposure time is insufficient

4. The quality of ink and solvent is also one of the causes of plate blockage. If the ink has poor fluidity, the printing viscosity is too high, the ink has deteriorated or is mixed with inks of different series, inappropriate solvents or solvent ratios are used, or even the operation of adding solvents to mix ink is improper, it will affect the transferability of the ink and cause plate blockage.

5. The ink has exceeded its shelf life or there are excessive ink additives
