UV Curing Systems
Ultraviolet curing (commonly known as UV curing) is a photochemical process in which high-intensity ultraviolet light is used to instantly cure or “dry” inks, coatings or adhesives. Offering many advantages over traditional drying methods., UV curing has been shown to increase production speed, reduce reject rates, improve scratch and solvent resistance, and facilitate superior bonding.
UV Curing Benefits:
- UV curing systems take up less space, so shops can utilize more revenue-producing equipment
- UV uses less energy, therefore significantly cutting operating costs
- UV ink goes farther than solvent-based ink (up to 60 percent per gallon)
- UV curing can increase throughput four times compared to solvent-based processes
- Nearly eliminates clean-up time, adding to the time available for production
- UV technology does not pollute, inside or outside the shop
In addition to printing benefits, UV curing is also used to instantly solidify coatings, inks, and adhesives with a cool, clean beam of light. Volatile Organic Compounds (VOC) found in the noxious, flammable solvents used by conventional coatings, adhesives and inks are completely eliminated. The ultraviolet curing process is a photochemical reaction where free flowing molecules, excited by UV radiation, link to form solid polymer chains. Small amounts of chemicals known as “Photoinitiators” act as catalysts, allowing the UV-curable adhesives and coatings to remain liquid, then instantly solidify or “cure” the material after a few seconds of exposure to Ultraviolet (UV) light.
