Hello, in this video you will discover the two proposed impressions for the prints of the photos. High quality prints are made by a professional laboratory. If you want to add a light rendering to your photos, choose the 4 mm thick plexiglass print. Plexiglas photo prints are the standard for art galleries and photo exhibitions. This translucent support will make the images sharper, highlighting the depth of color and clarity of detail. The prints on a 3mm aluminum aluminum plate (Alu dibond) have a less glossy finish with a slight matte finish. The rendering therefore avoids reflections. The impressions on aluminum dibond are water resistant, so that they can also be used outdoors. Both formats are stable, rigid and lightweight. With the 3 M band fastening system, you can expose photos in minutes and without damaging your walls.
