UV system helps in maximizing the production possibilities. It takes fractions of second to cure inks and varnishes. The phenomenon is also known as UV drying. UV system consists of following components: Reflectors, UV lamp, lamp housing, electronic open and closed loop control and cooling system.
Types of UV Light
UVA- (315-400 nm) This is known as Blacklight. It is Used for low energy UV polymerization reactions, also for fluorescent inspection purposes.
UVB- (280-315 nm) It is Used with UVA for polymerization and accelerated light aging materials. It is the light responsible for sun tanning.
UVC- (200-280 nm) It is Used for rapid surface cure of UV inks and lacquers, also for sterilization and germicidal applications.
VUV- (100-200 nm) It is called Vacuum UV. Can only be used in a vacuum and therefore is of minor commercial importance.
Types of UV Curing
1. Free Radical Systems: Majority of UV products are of free radical type. If we keep in mind the product properties, free radical systems are more versatile.
2. Cationic Systems: cationic systems are less versatile because of less use of monomers and oligomers. These systems are easily poisoned by high humidity.
UV Interdeck System is available for:
- Air Cooled UV Interdeck System
- Water Cooled UV Interdeck System
Air Cooled UV Interdeck System:
Air Cooled UV system combines infrared heat energy and air management system which incorporates high velocity air jets and higher volume air exhaust. It makes possible to efficiently produce high quality graphics and inline finishing.
Water Cooled UV Interdeck System:
When UV energy pass through the machine and cure inks and coatings, water cooled UV system uses chilled water to cool the lamp head and filter out the unwanted infrared heat. The system helps in good quality inline finishing.
Advantages of UV System
In recent years, UV curing has emerged to be a versatile and reliable technology. The following quality advantages speak for themselves:
- No solvents
- No pollution
- No extra energy required
- Less spoilage
- Good scratch resistance
- Low odor
- Low volatiles
- Less time
- Less Labor
UV Systems can be adopted for a wide variety of printing jobs. For opaque white printing jobs ,the use of a WhiteCure Inter deck dryer results in better curing up to 30%. For heat sensitive materials, the use of a TwinRay UV module is possible. The result is a heat load up to 40% less on the printing material and into the press than the standard.
Limitations of UV System
The material to be cured must see the light suitable in both wavelength and intensity.
