Photolithography
As photolithography , also Photogr. Imit. Printing or printing in "photographic tones" was the name given to a lithographic technique in the last quarter of the 19th century , in which photographs were transferred manually and graphically and reproduced using the means of lithography. So it was a matter of displaying a photograph with its typical halftone values, but not a photomechanical process. Various techniques were combined, such as pen and chalk lithography.
This technique found widespread use , especially in the field of postcards and Leporello albums . The aim was to reproduce the motifs as faithfully as possible. Photo prints, which at first could only be made as single prints, would have been far too expensive in this context. Photolithographs at least came close to the impression of a photograph. From the mid-1890s onwards, the technology was superseded by chromolithography for postcards , but was still used in Leporellos around 1900.
Photolithography should not be confused with the printing process known today as photolithography , which is based on converting the tonal values of a photograph into a dot matrix and was developed by Georg Meisenbach in 1881 . As an autotype , this process was initially used primarily in newspaper and letterpress printing and was only used in the postcard sector from 1900. As early as the 1920s, however, there seems to have been a certain equation and thus confusion of the terms.
Photolithographic fanfold albums are often offered on the Internet.
