Printing : a practical treatise on the art of typography as applied more particularly to the printing of books
A practical treatise on printing and typography by Charles Thomas Jacobi, published in London by George Bell and Sons in 1890, written for printers and those learning the trade. The four pictures are numbered line engravings of printing-press machinery: a hand-operated roller, a metal press bed with a screw, a flatbed plate press with labelled parts, and a cast-iron table press with a crank handle. Their clean outlines and crosshatched shading show how mechanical parts were drawn for technical reading.
