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.
