UV LED Curing Shines Through

Traditionally, mercury based UV lamps have been utilised for curing, but now more energy efficient and environmentally friendly LED based UV technology has proven a superior solution to the printing industry. LED curing technology uses semiconductor based light emitting diodes to project ultraviolet light when an electric current is passed through them. When a light-emitting diode is forward-biased, electrons are able to recombine with electron holes within the device thus releasing energy in the form of photons. The colour of the light emitted or corresponding energy of the photon is determined by the energy gap of the semiconductor material.

LED lamps provide many advantages including lower energy consumption, longer lifetime, improved robustness, smaller form factor, and faster on/off switching.

More Uptime: LED curing units have been proven to support trouble-free press operation. There is no warm-up time due to the instant on/off nature of LEDs. No moving parts, shutters to clean or bulbs to replace leads to higher press usage and operator efficiency. LED also offers higher yields due to consistent energy output.

Faster Throughput: Presses with LED perform at 20-30% faster speeds on average, assuming other portions of the workflow can operate at the higher speeds.

New Capability: Due to the long wavelength range of UV LED, it has the ability to cure previously difficult inks with reliably higher quality at faster speeds. UV LED inks are available with colors matched to traditional inks for a smooth transition. Check with your ink supplier for details.
