Drypoint vs Etching
ドライポイント / エッチング／腐食銅版画
Both sit in Intaglio Printing, so the question is not what they belong to but how they behave. They are reached for with different intent, which is the fastest way to tell them apart.
Drypoint
An intaglio method that scratches the plate directly. Ink held by the groove and its raised burr gives the line a soft fringe, ranging from dense black to a faint trace. Unlike etched lines, these marks need no acid; the burr wears during printing, so impressions can differ.

A needle draws through the acid-resistant ground and the acid bites the metal it exposes, cutting lines into the plate that are thin, fluid and close to handwriting.
| Drypoint | Etching | |
|---|---|---|
| Era | 15th century–present | 16th century– |
| Family | Intaglio Printing | Intaglio Printing |
| Kind | Technique | Technique |
| Cues | Small irregularities in scratched lines / Soft fringes from the raised burr / Dense black beside faint marks / Line character changes between impressions | Thin flowing lines / Depth by biting / Cross-hatching / Plate marks |
| Best used for | Exhibitions and teaching that compare Drypoint with neighbouring print techniques · Publications studying lines, tones and paper through documented works | Series of travel notes or figures that keep the speed and hesitation of drawing · Book illustration where atmosphere and shadow must come from line alone |
| Type | Keep lettering in the work separate from added labels; place medium, artist and date outside the image. | Draw the lettering with the same needle so its weight matches the image |
| Composition | Compare line density and softness in both details and whole impressions. | Build tone from hatching density and keep bare paper as the brightest area |
| Material | Check the collection medium record and the paper and ink; do not infer materials from screen colour alone. | Vary line depth by bite time, stopping out in stages as the acid works |
| Caution | A fuzzy digital line does not identify drypoint. Check the plate process and mixed techniques; later impressions may have less burr. | A uniform pen line filter is no substitute, since bite time, overlapping lines, ink left in the wiping and press pressure make the difference, and layering without timing fills detail with black. |
