Thermographic printing is a process where the item is printed using a slow-drying lithographic ink which then has thermographic resin applied and then heated to get the raised finish.  This resin is available in a matt or high gloss finish which allows the ink color to show through. By printing text and graphics in two or more spot colors, this means that the artwork can contain multiple colors. The resin is also available in gold and silver for a metallic finish.
