For Sheet-fed Offset Presses
For Flexible Packaging Industries
For Narrow to Medium Web Printing Presses
UV Curing technology was introduced to the printing world in late 80’s and proved to be ground breaking with never before print solutions and applications. Now substrates thought impossible to print upon could be printed and with ease, predictability and at good speeds. High deposits of inks/ coatings were suddenly possible with instant drying properties of UV technology. In short the revolutionary technology opened a whole new world of printing solutions, innovation and creativity.
For over 3 decades mercury medium pressure lamps were primary source of UV radiation. For such a long time inspite of being cumbersome and highly power inefficient these system ruled the world of UV equipment as no other alternative technology could come even close to Medium pressure Mercury Lamps. LED’s as a source of UV radiation were there as an idea since a long time but it is only now that LED’s have become a reality overcoming many technical hiccups over last many years with development and advancements in LED manufacturing technologies accompanied with development in compatible inks/ coatings. LED’s have now become a reality unleashing another revolution in lifeline of UV printing world with advantages of massively energy efficient, low heat, long life LED UV curing solutions. So come lets explore the magical world of UV printing now with LED UV curing with us.
|General Features||MERCURY UV||GLED UVs||ADVANTAGES OF LED|
|Core of System||Silicon Diode LED||Fragile cylindrical quartz bulbs||High resistance to vibration and shock|
|Power Consumption||Low normally quantified in hundreds of watts/hr||High, normally quantifies thousand of watts/hr||Power consumption is 60% less: thus investment cost is recovers by the user in a short time|
|UV Source Life Time||More than 20000 working hrs||Varying from 500 to 2000 working hours. It depends on the condition of use and the environment||No UV emitter to replace, No technical maintenance|
|Heat Generated by Lamp||60 C max, measured in lamp emitting window||Greater than 150 C on lamp window. The bulb can reach 900 after a few minutes of operating||Lower heat implies lower heat built up in presses|
|Radiation Type Emitted||Pure UV||Rays emitted UV-A+UV-B+UV-C+IR||Improved safety for the operator. It does not emit Dangerous UV-C radiation|
|Environment and Health||No mercury and other dangerous substances||Contains mercury and metal halide potentially dangerous for the environment||It is not necessary to dispose emitters as special waste|
|Maintenance Required||Glass window cleaning only||Frequent ordinary maintenance: glass cleaning, periodic replacement of UV bulb, replacing reflectors, cleaning filters||Almost absent maintenance cost and production downtime|
