1885 Annual Report: "The unique method of stereotyping, by which is secured a flexible stereotype plate, made of tin foil, amalgamated to a sheet of ordinary roofing tin, is the quickest, and cheapest, and for embossing work the best method in use. The double-cylinder press, made from special designs, prints four pages at every revolution, and will make thirty or more revolutions a minute. The flexible plates adapt themselves to the cylinders without any planing, and the character of the embossing speaks for itself." APH produced its first alphabet card for Revised American Braille (Grade 1.5) in 1918.
