The hectograph or gelatin duplicator or jellygraph is a printing process that involves transfer of an original, prepared with special inks, to a pan of gelatin or a gelatin pad pulled tight on a metal frame.
While the original use of the plate has faded, it has recently been revived for use in the art world. The hectograph has been modernized and made practical for anyone to use.
