STIPPLE ENGRAVING

Stipple engraving is an indirect technique of engraving, that is without acids, used especially on copper or zinc plates. Differently than in the chalcographic technique, a stippling tool is used to create images with dots.

The stippling forms a ground of burrs on the plate and, as in the dry point technique, the artist can either remove or leave them, depending on the effect he wants to achieve.
