Gloss
Shine on with vivid colors
With their gently reflective surface, glossy Displates offer enhanced contrast, highlighting vibrant hues, deep blacks, and intricate details.
Go for gloss if you're looking for a photo-like finish. For best effect, try to avoid direct light when arranging your posters.
Matte
Sleek, soft, and elegant
The subtle matte finish draws more attention to the smooth metal surface of your Displates, absorbing light and enhancing their elegant, soft texture.
The colors are slightly toned down, making this finish a perfect fit for all atmospheric illustrations and paintings.
