 It occurred to Boni that if he could reduce rather than enlarge photographs this technology may enable publication companies and libraries to access much greater quantities of data at a minimum cost of material and storage space.Over the following decade, Boni worked to develop microprint, a micro-opaque process in which pages were photographed using 35mm microfilm and printed on cards using offset lithography.This process proved to produce a 6" by 9" index card which stored 100 pages of text from the normal sized publications he was reproducing.
