UV Led printing
This method is a type of digital printing that utilizes ultraviolet lights to dry up ink during the printing process. While the printer produces ink on the surface of the object (also called a "substrate"), the specially made UV lights will follow close behind, drying the ink immediately. This method was first developed for quick-dry gel nail polishes. It was then expanded into other industries around the world.
- Finer details are obtained through UV printing because the dots of wet ink don’t have a chance to spread out once printed;
- UV prints are more resilient to environmental factors and fade more slowly;
- Does not use solvent inks that release harmful compounds, like the traditional printing method;
- It speeds up production time and delivers higher quality prints;
- UV printers can accommodate oddly-shaped objects.
- The high upfront cost of the printer;
- Does not produce good results on silicone substrate;
- Not suitable for items that are subjected to repeated dish washing, such as drink ware;
- Not suitable for garments;
- Has a big learning curve for printing operators.
This method can be used to print on almost anything, but is not recommended for items that require frequent washing at high temperature.
