Cerography

Cerography or glyphography is a printmaking technique related to engraving, using a layer of wax over a metal substrate.

After the image is engraved into the wax, a positive plate is produced through stereotyping or electrotyping.

As compared to lithography and copperplate it had the disadvantage that it could not reproduce fine shading well.

Tones were added by scoring fine parallel lines 100-150 per inch or by rolling stippling spikes over the surface of the wax to create parallel dotted lines.

[2] The technique remained popular to the end of the 19th century but was gradually pushed out by photoengraving.
