Paul Mehner soon realised that chromo lithographic printing process (slow and costly) alone would lead to disadvantages. Similar to competitors, M. & M. introduced an Autochrome-like process (halftone image, 3 to 4 colours superimposed by litho process) by early 1901 which they named “Auto-Bunt”. A bit later collotype printing presses were installed.
According a 1907 published printing trade directory, M. & M. had just 3 litho presses and employed 40 persons. Wondering if this entry is fully correct / up-to-date.
