This dissertation analyzes the transitions of uses that the techniques of reproduction of images have passed through. The study identifies different functional outwardness assumed for such doings, and, among them, it privileges the specifically artistic approaches: those using techniques that lost their functional use and those that appropriate of techniques strictly marked until then by this functionality. In that context, it is, then, studied the performance of Lithos Edições de Arte, graphic workshop founded in 1973, in Rio de Janeiro. Along 35 years, Lithos is working close to important names of the Brazilian arts, offering them the possibility to carry out serial works in screen-printing and lithograph. Since 2005, this workshop accomplishes a pioneer experience with the new technique of digital recording of offset matrices, CTP, computer-to-plate. Developed and addressed for the graphic industry, in Lithos, those matrices are adapted and printed in a lithographic press Marinoni, of the century XIX.
