Book Summary
Sir William Congreve (1772-1828), a pioneer in the military use of rockets, was a Member of Parliament. He developed a machine for printing complex patterns in two colors using interlocking compound plates (Patent No. 1820/4,521). The printing process came to be known as the "Congreve Compound Plate Printing Process." The Congreve machines were used in British India to print revenue documents like Hundis & Stamp Papers.
