Nature prints of plants were produced by drying the actual plants, pressing them between a plate of soft lead and one of steel, making an impression on the lead plate, and making an electrotype from the lead plate. Electrotypes were made by putting the plate into a solution of copper and passing electricity through it, causing the copper to be deposited on its surface. After a few weeks, the copper would become rigid and could be lifted from the lead plate, complete with the image, which could be inked and used for printing.
