Understanding Backlit Film for Lightbox Applications

Even illumination and accurate color come down to choosing the right backlit substrate.

Why diffusion matters

Backlit film spreads light evenly across the graphic, preventing hot spots and banding when the lightbox is switched on.

High-quality coatings support high-resolution printing up to 48-pass for crisp, color-accurate output.

Choosing the right base

PET and PP bases each have their own stiffness and cost profile. Select by lightbox depth, mounting method and expected service life.
