WHAT EXACTLY IS UV-LED PRINTING?
Great question! UV-LED printing offers instant curing of a digitally printed image, with the ability to print onto a WIDE variety of printable substrates. With instant curing, it is possible to achieve a unique layered texture, or raised printing effect, providing a dimensional (tactile) print. UV LED Printing is environmentally friendly, with minimal emissions and low energy consumption.
WHAT IS UV-LED CURING?
UV curing references the photopolymerization process that uses UV energy to change a liquid to a solid. Upon absorption of the UV energy, the photoinitiator (PI) produces free radicals which initiate cross-linking with binders (monomers and oligomers), in a polymerization reaction to cure or solidify the ink. WHAT! WHO CARES? What is important is what you can do with UV LED printer technology.
WHAT CAN I PRINT WITH A UV-LED PRINTER?
Just about anything! UV/LED Printers can print on a wide variety of substrates including: acrylic, glass, metal, powder coated substrates, polystyrene, PVC, wood, ABS, art board and canvas, a variety of vinyl and many additional RIGID and FLEXIBLE substrates.
UV/LED inks allows for instant curing with strong adhesion for lasting and durable prints. Although adhesion promoters are advised for some substrates, many can be printed easily without any additional preparation.
ADVANTAGES OF UV-LED TECHNOLOGY
- LED lamps last 20,000+ hours vs. 2,000 hours for mercury lamps
- No downtime to change lamps or consumable lamp costs
- Instant on/off and no degradation of intensity with toggling
- Contains no mercury, obviating need for disposal/recycling
- LEDs do not produce ozone gas with use while conventional mercury lamps do
