Definition of Siderography

1. n. The art or practice of steel engraving; especially, the process, invented by Perkins, of multiplying facsimiles of an engraved steel plate by first rolling over it, when hardened, a soft steel cylinder, and then rolling the cylinder, when hardened, over a soft steel plate, which thus becomes a facsimile of the original. The process has been superseded by electrotypy.



Definition of Siderography

1. Noun. A 19th-century process of reproducing steel-engraved designs for printing. The design is engraved on a steel block, then hardened and used to transfer a raised-image version to a steel roller under heavy pressure. The roller is then hardened and used as a die to impress duplicate images on printing plates for transferring to paper by the intaglio method. ¹
