UV applications for CD/DVD manufacturing include the following:
Decorating
Both CDs and DVDs are decorated on the non-data side with UV curable screen inks that are typically 6-8 microns thick. Most screen inks are formulated for longer wavelength (365nm) to cure more effectively and achieve adhesion, so high irradiance is essential. To achieve the highest cure speeds with the least amount of heat, linear travel is recommended so the disk can pass under the lamps at a constant velocity at the focal point of the UV lamps. Though less efficient, UV curing can also be used on rotary (carousel) machines where the disks index through. |

Protective Clear Coatings
UV curable clear coatings are applied to protect the data on the disks. UV coatings provide superior abrasion and scratch resistance with high production rates. The application of the coating is almost always done by a dispense-and-spin (spincoat) method, followed by exposure to a UV lamp.
Adhesive Bonding
DVDs are made by gluing two optical media disks together. UV curable adhesives are applied and are then cured by shining the UV light through the clear plastic disk prior to decorating.
