Die umbildung der chromolithographie : photolithographischer vier-und menrfarbendruck auf stein, zink und aluminium
A 1913 German technical manual by Theodor Kirsten, published privately in Hannover, on photolithographic multicolour printing onto stone, zinc and aluminium for printers and lithographers. The pictures are plain line diagrams and workshop sketches: a glass plate, concentric frame layouts with registration marks, a camera apparatus with a rotating plate holder, and a hand pouring developer across a plate. A designer might borrow their clean, schematic line work and the layered rectangular plan for diagram-style graphics.
