Apprentice typographers learned the trade on the job; instruction manuals were wasted on them. That such books were made all the same is owing to “the relative small number of the most educated and ambitious master printers and overseers” (Janssen, ed. Wardenaar, 11). One such man was Joannes Josephus Balthazar Vanderstraelen from Antwerp who, in 1784–5, wrote an instruction manual explaining how to place type for different formats into the forme in the correct manner.
