UV light is a part of the electromagnetic spectrum. The wavelength of the UV light ranges from 50 to 400 nanometers. In comparison, visible lights have slightly longer wavelengths and X-rays have shorter wavelengths. The sun emits lights at all different wavelengths of the electromagnetic spectrum, causing UV lights to emerge as sunbeams. Most of these UV lights that are emitted from the sun reach the surface by passing a part of the atmosphere while being held by various, especially ozone, gases. WHAT A UV INK? UV inks are widely used in the printing industry for more than 20 years and their use is becoming increasingly widespread. Water-based and solvent-based inks used in other printing technologies include water or solvent that must evaporate during post-press drying. In UV inks, drying or fixing must be carried out while applying ink to the ink. In simple terms, the ink is applied to the surface and instantly dried / fixed by instant UV light. Since there is little or no solvent in UV inks (there are no Volatile Organic Compounds in the world) and therefore little effect on environmental pollution, there is a growing interest in its use. UV inks offer some important advantages for printing systems. One of its most important advantages is that it allows the image to be fixed in the desired properties due to the instant drying feature. As a result, the large and complicated drying system provides the possibility of printing at high speeds unnecessarily. Since UV inks do not dry in the reservoirs, it also allows the removal of annoying problems, such as cleaning of the cups, that affect the yield and workflow. UV ink does not penetrate the printing material, such as solvent ink, but allows it to be printed on a much wider range of printing materials as it remains on the surface. The prints made with UV ink are completely water-resistant and the light is more durable than the solvent prints. HOW TO OPERATE UV INK? UV Inks consist of monomers, oligomers, photo-triggers, pigments and various additives to control specific parameters of ink performance. The mechanical fusion or polymerisation process that occurs when the ink dries is carried out by the photo-triggers by the method of absorbing light at certain wavelengths from the UV Light source. When the light is absorbed, reactive particles or free radicals are formed and the associated polymerization reaction is initiated. As the polymerization proceeds, the ink film becomes more mechanically cohesive and imparts rigidity, gloss, flexibility and adhesion properties to the ink film. WHICH MATERIALS PRINT WITH UV INK? Plexiglas, forex, photoblock, PVC, wood and other hard materials are able to print with UV ink.
