3M 7100082544 Lithographers Tape 616 Ruby Red 0.25in X 72yd

Product Description

The 3M 7100082544 is a ruby red UPVC film tape with a rubber-based adhesive, supplied in a 0.25-inch-wide by 72-yard roll at 2.4 mil (0.06 mm) total thickness. The film is optically transparent yet photographically opaque, a combination that makes it well suited to precision masking and registration tasks in the graphic arts and printing trades. The rubber adhesive provides firm, repositionable hold to film, glass, and smooth substrates without leaving heavy residue. Graphic arts technicians and print production professionals are the primary users of this tape.

This tape is designed for lithographic stripping applications in the graphic arts industry. Typical use cases include masking film positives and negatives during plate-making, aligning and registering film flats, and blocking out areas that must remain unexposed during contact printing. Its photographically opaque ruby red color ensures clean, defined edges when the assembly is exposed to UV or arc light sources common in traditional plateroom workflows.

Key Features

• Optically transparent and photographically opaque UPVC film backing
• 2.4 mil (0.06 mm) total tape thickness for precise, low-profile masking
• Rubber adhesive bonds to film and smooth substrates without heavy residue
• Ruby red color provides clear visual contrast during film stripping
• 0.25-inch width suits fine-detail registration and edge-blocking tasks
• 72-yard roll length reduces mid-job changeovers on production work

Compatibility

Designed for lithographic stripping and film-masking applications in the graphic arts industry. Suitable for use on film positives, film negatives, and smooth glass or drafting surfaces common to plateroom and prepress environments.

Installation Notes

Application is performed by hand; no special tools are required beyond a straight edge or registration ruler for precise placement. Clean the substrate surface of dust and oils before applying to ensure proper adhesion and clean lift-off. Avoid stretching the tape during application, as distortion in the backing can compromise registration accuracy. Store unused rolls away from direct heat and UV light to preserve adhesive performance.
