Patent Model for a Chromolithographic Press

Patent Model for a Chromolithographic Press

Description (Brief)
This patent model demonstrates an invention for a chromolithographic press which was granted patent number 89997. The patent details a flatbed scraper machine with automatic inking, damping, feeding, and delivery. It printed at the rate of 300 impressions per hour, with the precise registration necessary for multicolor printing.
August Hoen (1817-1886) was born in Germany and came to the United States with his family in 1835. He worked with his cousin Edward Weber in a Baltimore lithographic shop. After Weber's death in 1848 Hoen took over the company and renamed it the A. Hoen & Company. Both under Weber and Hoen, the shop specialized in manufacturers' ornamental labels, and was known for its exceptional color work. Hoen's lithocaustic process was well adapted to this work.
