Sorry, but I'm a bit confused. "Dry-point" generally (I thought) refers to the image printed from an engraved plate. When a copper plate is engraved by a graveur it raises a fuzzy edge along the edge of the incised line. When such a plate is inked and printed the resulting image is called "dry-point"

There is no such thing, to my knowledge, as a "dry point" etching. Etching is a totally different intaglio process.
