Cover
An external document coating. A design element in the form of a sheet of thick paper, plastic or cardboard covered with synthetic material. Images and text on the front side of the cover are applied by foil stamping, blind embossing or printed in ink. Printing with UV luminescent or anti-Stokes inks is an additional security feature for the cover. By the properties of document coating, covers can be soft (easily bent) and hard (bent with effort). The cover is attached to the book block. It can be glued, stapled or attached with a thermo thread.
