Advance Details of the Toyo Ink Exhibit
1. Compared to conventional lamps, LEDs consume much less electricity (roughly 1/4). This is due to the fact that, whereas UV lamps use an arc discharge luminescence mechanism, LEDs harness the electroluminescence of semiconductors. This effectively makes it possible to cut energy costs (electricity bills) and substantially reduce CO2 emissions.
2. As the light emitted by LEDs does not contain any infrared, the amount of heat generated in minimal. This makes it possible to print onto films and other materials with a low level of heat resistance and minimizes the effects of heat on the printer itself, which in turn means that fewer adjustments are required in terms of printing precision, reducing printer wear and tear.
3. As LEDs have a substantially longer life span when used as a light source element compared to lamps (roughly 12 times as long), they need to be changed much less frequently.
4. LEDs can be turned on and off instantly, thereby eliminating the need for warm up and cool down periods, as with conventional lamps, and improving operational efficiency.
5. As UV curing units are exceptionally compact, they don’t take up lots of space when installed like conventional equipment.
The range of emission wavelengths for LEDs shows much sharper peaks compared to UV lamps. In an effort to achieve efficient drying properties based on this characteristic range, Toyo Ink has developed and optimized new pigments, resin monomers and photo-polymerization initiators to create the “FD LED Series”. We believe that the collaboration between such new inks and systems will bring about major innovations in conventional UV printing systems, making it possible to save both energy and space.
It addition to showcasing the “FD LED Series” in its own booth at drupa2008, the Toyo Ink Group also plans to put on printing demonstrations as a sample exhibit in the booth belonging to Ryobi Limited (Hall 17, Booth A06), which has developed a printer equipped with an LED-UV printing system.
