What Is UC900 Translucent Film?

Avery Dennison UC900 is a premium quality, highly durable translucent cast vinyl film designed specifically for internally illuminated signage. Unlike standard opaque vinyl that blocks light, or transparent vinyl that lets too much light through, UC900 is engineered to diffuse light evenly.

This ensures that your sign colors remain vibrant and consistent whether they are viewed in direct sunlight during the day or backlit by LEDs or fluorescent tubes at night. It is the professional choice for channel letters, light boxes, and architectural backlit signs.

Backlit Sign Applications

UC900 is the industry standard for illuminated branding, offering excellent conformability and long-term outdoor performance.

A

Channel Letters

Perfect for the acrylic faces of individually illuminated 3D channel letters used on retail storefronts.

▣

Light Boxes

Applies smoothly to flat or thermoformed rigid plastic and flexible sign faces for cabinet signs.

◫

Monument Signs

Durable enough to withstand harsh outdoor weather conditions on ground-level architectural signage.

◉

Franchise Signage

Provides exact color matching required by corporate branding guidelines for day and night viewing.

Maintaining Color Consistency

The biggest challenge in illuminated signage is ensuring the brand color looks the same when the sign is turned off during the day as it does when illuminated at night. Avery UC900 solves this through advanced pigment technology.

The cast film construction features evenly distributed pigments that diffuse the light source behind it, eliminating hotspots and preventing the color from washing out. This guarantees that a corporate red remains the exact same shade of red 24 hours a day.

Frequently Asked Questions

What is translucent vinyl? +
Translucent vinyl is a specialized film designed to diffuse light. When placed over a light source (like in a sign cabinet), it illuminates the color evenly without showing the individual bulbs or LEDs behind it, while still looking like a solid color during the day.
Can UC900 be used outdoors? +
Yes. Avery UC900 is a premium cast vinyl with an outdoor durability rating of up to 9 years. It is highly resistant to UV fading, weathering, and temperature extremes.
Does UC900 work with LEDs? +
Yes, UC900 works exceptionally well with LED lighting. Because LEDs can sometimes create intense hotspots, the diffusing properties of UC900 are ideal for creating a smooth, even glow across the sign face.
How long does UC900 last? +
When properly installed vertically, Avery UC900 Translucent film offers an expected outdoor lifespan of up to 9 years for most colors.
Can UC900 be printed? +
While UC900 is primarily designed as a cut-color film for plotters, it can be thermal transfer printed. For wide-format digital inkjet printing (solvent, eco-solvent, latex, UV), Avery offers specific printable translucent films.
