What is the difference between UV ink and LED-UV ink?


The main difference between UV ink and LED-UV ink is the light source used to cure the ink. UV ink is cured using a mercury vapor lamp, while LED-UV ink is cured using light-emitting diodes (LEDs).

Here is a table summarizing the key differences between UV ink and LED-UV ink:

UV Ink

LED-UV ink has several advantages over UV ink, including:

  • Efficiency: LED-UV inks are more efficient than UV inks, meaning that they require less energy to cure. This can lead to significant cost savings, especially for large print runs.

  • Heat production: LED-UV inks produce less heat than UV inks, which can be beneficial for certain substrates, such as heat-sensitive plastics.

  • Ozone production: LED-UV inks do not produce ozone, which is a harmful gas. This makes LED-UV printing a more environmentally friendly option.

  • VOC emissions: LED-UV inks do not emit VOCs, which are volatile organic compounds that can contribute to air pollution. This makes LED-UV printing a healthier option for both printers and consumers.


However, LED-UV inks are also more expensive than UV inks. This is because the LED curing technology is more recent and therefore more expensive to develop. However, the cost of LED-UV inks is expected to come down as the technology becomes more widespread.

UV Offset Ink

Overall, LED-UV ink is a more efficient, environmentally friendly, and healthier option than UV ink. However, it is also more expensive. The best choice for you will depend on your specific needs and budget.
