3M Lithographers Tape 616 is a Ruby Red 2.4 mil unplasticized polyvinylchloride (UPVC) film tape with a rubber adhesive. The low caliper, pin-hole free, colored backing allows for accurate positioning while minimizing ghosting and simultaneously providing sharper definition with a continuous opacity to light to help minimize retouching. This tape is resistant to changing atmospheric conditions which allows for repeated and extended burn times. We’ve designed this tape with a firm, long-aging rubber adhesive that is resistant to softening. It resists oozing during both application and storage, ensuring a long life and continued performance during processes.
