What the overcoat does on a dye-sublimation photo print
A clear finishing layer is part of many event-print media systems.
A glossy booth print may have a clear outer finish that protects the colour layer and changes how light reflects from the surface. Do not mistake the finish for an extra image colour channel.
Read the media specification
Some dye-sublimation printer ribbons include a clear overcoat applied after the colour panels. Supported finishes can vary by model and media. Check the exact printer and consumable documentation instead of assuming every booth print has the same coating.

Inspect gloss and texture
Tilt a finished print under diffuse light to see how the surface changes reflections. Matte and glossy modes can make identical image values appear different because the surface scatters or reflects light differently. Compare samples under the same viewing angle and room lighting.
Keep handling gentle
Follow the media manufacturer’s storage and handling advice. A coated surface is not a reason to expose the print to heat, solvents or aggressive cleaning. If fingerprints or marks appear, make a new print from the saved image rather than testing household cleaners on the original.
