Fig. 1 "Social Smoke" litho stone and finished label __________________________________________ Chromolithography, or the technique of "printing in colors," had a dazzling and meteoric life. After centuries of black ink on white paper, chromo-lithography burst onto the American scene about 1840 and then vanished by the 1930s. But during this nearly one hundred year period, chromolithography revolutionized the printing industry and intoxicated the world with lush colorful hues. It transformed calling cards, wedding announcements, greeting cards, tickets, cigar box labels, advertising posters and many other types of printed ephemera into eye-catching works of art that proved too beautiful to be thrown away after temporary use.	Fig. 3 "Liberty Light" original watercolor sketch, innner and outer finished labels, and photograph of artist Henry Maier. __________________________________________ The chromolithographic process began with detailed watercolor "sketches" created by commercial artists like Henry Maier (Fig. 3). Skilled lithographic artists transferred these designs by hand onto Bavarian limestone printing slabs. Drawing in black, in reverse image, and one image for each color, litho artists visualized how all colors would interact and overprint to re-create the original watercolor sketches (Fig. 1). As many as twelve colors... and twelve stones... were printed in sequence with amazingly accurate registration. Images were "polished off" the stones when all printing editions were completed. The stones were then prepared for the next job.

The lithography part of chromolithography was invented by Bavarian printer Aloys Senefelder around 1798. Based on the principle that oil and water do not mix, Senefelder drew images on stone in greasy crayon, covered the remaining surfaces of stone with a thin film of water, and then applied printing inks to the stone. He discovered that the greasy images attracted the printing inks while the non-greasy surfaces repelled them. __________________________________________ ©2016 All Rights Reserved.
