Calder art prints are high-quality prints on special, mostly heavy or textured papers. The printing technique is chosen so that the colors and the haptic impression of the original are reproduced as faithfully as possible. Art prints are often made with decorative colors such as gold and silver as well as embossing. In contrast, posters designate any form of decorative print. Often thinner papers and simpler printing techniques are used. Since the differences between art prints and posters are not familiar to most people, we use the terms here synonymously, but usually mean the high-quality art print.
