2. What is LED UV printing?
 Faster Drying For A Quicker Turnaround. The unique selling point of an LED UVprinter is the unique drying method called UV curing. UV curing uses light instead of heat when drying, meaning it takes only a couple of seconds to harden the adhesives, inks or coatings that have been used.

3.What is UV flatbed printer?
Flatbed digital printers usually use UV curable inks made of acrylic monomers that are then exposed to strong UV-light to cure, or polymerize them. This process allows for printing on a wide variety of surfaces such as wood or canvas, carpet, tile, and even glass.

4. How long does UV printing last?
Typical UV cured prints have an outdoor durability of at least 5 years without fading, or up to 10 years or more without fading when laminated. However, the specific environment and application in which the print is used will ultimately determine whether the print will last for more or less than 3 years.
