Etching may'also be done by stippling or laying a benday oversuch parts as may be desired, leaving a printing sur face of both plates where a combination of both colors are desired.

B. In the case of two or more plates and one or more electrotype original or duplicate plates, similar methods are. followed except that additional fine effects may be accomplished high lights and darken'ingoi the shadows in one or more of the plates.

It is apparent that. in either or both of the above illustrations, dilier'ent combinations are-possible, and some obicctsor parts in the design are made to stand out and others subdued, by varying the etching and routing out in the plates, and by varying the colors and degree of transparency of the inks. 5

It is evident that variations in the basicprincipleyherein disclosed may be employed "within the scope of iny invention, both as respecting the character of the plates and i ..-,lf 1emh-ter1al ipon which the printing is then performed on each color printing plates, making one or bv difierent etching of. the
