Artotype Invented by J. B. Obernetter of Germany, this process is a form of the collotype process, a photo-mechanical printing process and similar to that of the Albertype.  It was patented in America in 1878 and in Canada in 1879.   It looks like a full-toned albumen photograph, however it was printed on a lithographic press using ink.   This process was the precursor to half-tone engraving using dots.  Thousands of images could be printed economically and would be used in magazines and catalogues.  Lindop and Cooper, from St. Thomas were the driving force in bringing this process over from Germany".
