What gloss changes
Gloss increases specular reflection and can make color and dark areas feel visually deep. It works well where reflections are controlled and the viewer can move relative to the image.
What matte changes
Matte reduces distinct reflections and is useful near windows, overhead lights and public viewing areas. It can provide a calmer presentation for soft portraits, muted landscapes and informational graphics.
Fingerprints and handling
Frequently handled tabletop prints and small products may show fingerprints more readily on gloss. Handle panels from the edges and use the care method provided for the specific coating.
Test the actual room
Hold a sample vertically where the finished print will hang and observe it from normal viewing positions. Check daytime window light and evening artificial light; a finish that looks excellent in a sample kit can behave differently on the wall.
Artwork still matters
High-key photographs, dark cinematic images and metallic-style artwork respond differently to the same finish. Ask for a proof or sample when color, glare or brand consistency is important.
