Theodore De Vinne, The Invention of Printing (1876)
“ These peculiarities are never produced in the workmanship of men who draw letters on a block. It is not strange that the block-book printers should have imitated the work and the mannerisms of the typographers. It was easier to transfer the letters than to draw them; easier to cut the letters for a book of twenty or thirty pages than to cut the punches, make the moulds, and cast and compose the types. The blocks having been engraved, the block-printer had the superior advantage. His blocks, like modern stereotype plates, were always ready for use. ”
