Epson GS Trans Backlight Media 54X100 - S045340

Epson S045340 GS Transparent Backlight Media

Overview

The Epson S045340 is a 54-inch wide, 100-foot roll of GS Transparent Backlight Media engineered for large-format Epson GS-series inkjet printers. Transparent backlight media is purpose-built for illuminated display applications — lightboxes, backlit signage, trade show displays, and retail point-of-purchase panels — where the light source sits behind the print. Unlike opaque or standard glossy stocks, this substrate transmits light through the print layer, so color density and ink saturation directly affect how vivid the finished display appears when lit. Using genuine Epson media with GS-series printers ensures ink adhesion, color profile accuracy, and output consistency that third-party substrates can compromise.

Compatibility

The S045340 is designed for Epson GS-series large-format printers. Verify your specific GS-series model's supported media list before ordering — not all GS printer variants support every substrate width or media type. The 54-inch width is a standard large-format roll size suited to wide-carriage GS-series units; confirm your printer's maximum media width accommodates 54-inch stock. Epson ICC profiles and RIP settings calibrated for this media type are available through Epson's media configuration tools for accurate color rendering in backlit environments.

Installation Notes

Load the roll with the coated/printable side facing the printhead — installing a backlight substrate backwards produces unacceptable output and wastes media. Backlight films are dimensionally sensitive to temperature and humidity; allow the roll to acclimate to the print environment before loading to reduce cockling and edge-lift. Store unused rolls horizontally in original packaging away from direct light and heat to maintain coating integrity for the full 100-foot length.
