It can produce results difficult to distinguish from metal-based photographic prints because of its microscopically fine reticulations which compose the image. Many old postcards are collotypes. Its possibilities for fine art photography were first employed in the United States by Alfred Stieglitz. Because of its ability to print fine detail, it was also used for business cards and invitations with fine script lettering. Collotype originates front the Greek word kola for glue. It was invented in 1855 and the process was shown in 1859 by F. Joubert. Poitevin patented the idea of collotype printing the same year it was invented in 1855. In 1868 Joseph Albert and Jakub Hasnik developed some important components to the collotype process. The prints would only work with 100 prints or less because of an issue with the adhesive sticking to copper substrate. Albert and Hasnik found a solution that allowed the problem to be resolved allowing prints up to 1000 instead of 100. Even though the process was efficient, it took a handful amount of time. In order to combat the problem, the gelatin layer was replaced with cellophane foil. The number of facilities that still use collotype printing process include only a few since 2010.
