What is a Backlit Film?
Print custom backlit films to keep your message visible in dark or dim environments. Since they improve visibility, they are most popular in movie theaters, bus stops, airports, and restaurants. Additionally, the translucent material makes the colors appear vibrant rather than dull. This makes them prominent in department stores, malls, galleries, museums, and healthcare facilities.

Backlit Film Printing and Materials
Our backlit film printing process results in a long-lasting product designed for optimal exposure. The poster is non-adhesive and comes in a matte finish. It’s lightweight, 8 mil thick, and tear-resistant.
Backlit Film vs Backlit Decals vs Paper Posters
Backlit film differs from our backlit decals and paper posters in several ways. For one, they differ in material. Backlit film is made out of PET polyester. Backlit decals are made of vinyl, and paper posters are made of photo paper.
All three are placed in different areas. Backlit film prints are placed in lightboxes and mounted on walls or free-standing displays. Backlit decals are often applied to storefronts. Although these two items can be placed indoors or outdoors, paper posters should be placed only indoors. Paper posters should also only be applied to indoor walls.
There are also differences in size, installation procedures, and shape options.

Design Guidelines for Backlit Film Prints
Know your exact dimensions before you order your sign. Since the lightbox’s frame can cover the poster’s border, you should allow bleed room. The standard size for bleed is ⅛” to ¼” on all sides.
We recommend that you use a high-resolution image, increase the image’s contrast, and decrease its brightness. These three steps will help with the glow effect.
Furthermore, avoid thin fonts. Use bold typography instead. Sans-serif fonts like Helvetica and Futura are popular fonts for backlit posters. Keep all texts at least 0.5” to 1” away from the light box frame.
