The illustration of printed matters could be considerably standardised due to the lithography technique invented by Alois Senefelder. Finally, another invention was photography, whose establishment at the end of the 19th century led to the first halftoning and reproduction procedures. The step-by-step development of a modern mass society provided a growing demand of printed matters. Besides the traditional letterpress beginnings of a newspaper landscape as well as a broad market for publications, advertisements, and posters of all kinds appeared. The challenges had changed: since printing and typography had been a straightforward craft for centuries, it now had to face the challenges of an industry-ruled mass society. The 90 years between 1890 and 1980 coined typography until now. The craft of printing became an industry, and the typography became a part of it as well. Both stylistically and technologically this epoch was really tumultuous. The significant developments were the following:  Since impressionism the modern art styles were reflected in graphic design and typography too. Since 1890 the Art nouveau became popular. Its floral ornaments, the curved forms, as well as the emphasis on graphical realisation inspired the type designers of the start of the 20th century. A popular art nouveau font was the "Eckmann" designed by graphic artist Otto Eckmann. Furthermore, the influence of art nouveau was expressed in a lot of book illustrations and exlibris designs. Altogether the return to the roots of book art become stronger around the start of the 20th century. It was initiated by British typographer, socialist, and private press publisher William Morris as well as by the Arts and Crafts Movement, which refers to him. Essentially this movement initiated three things: a return to the antiqua-models of the Renaissance, clarity and simplicity of book illustrations, and straightforward technical processes during the production of printed matters. An immediate consequence of the Arts and Crafts Movement was the establishment of the private press movement, which more or less was committed to Morris' ideals, and whose remains partially are still present today. An established meeting point of this scene in Germany for example is the Mainzer Minipressen-Messe, which actually is held every two years. Especially the New Book Art movement, which formed in the decade before World War I, was influenced by the Arts and Crafts Movement. The young type designers of the pre-war era, among them Fritz Helmuth Ehmcke and Friedrich Wilhelm Kleukens, rejected both the late typographical classicism and the ornaments of the popular Art nouveau.
