A hundred years ago photographs had to be carefully rephotographed using giant cameras fitted with precisely scribed glass plates. A very high contrast negative was created in which the grays of the original photograph were converted to tiny dots of different sizes. The negative was used to acid etch a metal plate that would put ink onto paper. As a final check in quality control, a test impression of the plate, a proof, was made on presses like these or on newer cylinder presses. Although handpresses evolved from wine presses during the time of Gutenberg, this design, a "Washington", dates to the 1840's.
Here the type and a modern engraving of the Bernays engine is locked up in a chase with furniture and quoins, and ready for inking. |
