A Layman's Guide to What We Do
GEW are a global company who design and manufacture ultraviolet (UV) light systems for drying ink on printing presses. We sell our products both to companies who build printing presses and also the print houses directly.
Printing presses are used to reproduce graphical images in high volume. The process starts with a blank substrate, typically paper, as either a roll (or web, as it is known in our industry) or a stack of cut sheets. The substrate is fed through the press and the image is applied one colour on top of the other to form a complete image. After one colour is printed, the ink needs to be dried before the next colour is applied, otherwise the image will be ruined. The picture below shows how the press prints and dries one colour at a time to form a complete image.
Traditionally, printing inks were dried with heat, and in some cases this is still done today. UV printing uses inks that set hard, or ‘cure’, when they are exposed to ultraviolet light. For further information on how UV curing works please click here.
The UV systems are designed and built at our head office and manufacturing facility in Surrey, England, from where they are sold around the world.
