ABSTRACT:
A lithographic print of a color photograph which includes printed lettering in an area where the density of the ink dots which reproduce the photograph is reduced to enhance the visibility of the printed lettering.
The print is prepared by superimposing a screen having a substantially lower dot density over the portions of the color separation films corresponding to the area reserved for lettering and preparing the engraved printing plates from these screened films.
