There is no doubt that LED UV curing systems offer some
tremendous advantages with their ability to switch on and off and hence no need
to warm up or cool down, giving the printer tremendous productivity advantages.
This in turn leads to much longer lamp life, (Potentially 10 x longer than
typical mercury lamps), and considerable less maintenance needs, as they do not
need shutters or fans. LED cured inks do
have to be specially formulated and just like the conversion from water to UV
will take time for the variety and volume to become available on a global
Another major advantage of LED technology is its much lower energy
requirements so much so that it is at least 50% less than conventional UV. Environmentally, LED also leads the way not
just with less power consumption, but it also does not use mercury and being cool
does not generate any plasma. From a safety perspective the lamps are always
cool to the touch and do not create a short wave, meaning less risk to
the eyes and skin of the operator. As with all new technologies it does
presently cost significantly more to purchase but based on its many benefits
its payback could be in less than 12 months for most printers.
