Lithography prints from a flat surface whose image areas accept ink. Etching prints from ink held in recessed lines chemically bitten into a metal plate. Both use ink and pressure to make prints, but the way the printing surface carries the image is different.
If you are comparing an etching with a lithograph, start with the process rather than the subject or colour. A lithograph is a print made by lithography; an etching describes both a technique and a print produced by it.

Lithography vs etching vs engraving
| Feature | Lithography | Etching | Engraving |
|---|---|---|---|
| Process family | Planographic: flat-surface printing | Intaglio: recessed-image printing | Intaglio: recessed-image printing |
| Printing surface | Stone or prepared plate | Metal plate | Metal plate |
| Image formation | Chemical distinction between image and non-image areas | A chemical mordant bites exposed metal | A cutting tool incises the metal directly |
| Where ink is held | On the image areas of the surface | In bitten recesses | In cut grooves |
How lithography works
In traditional stone lithography, the artist draws with a greasy crayon or ink. Processing establishes ink-receptive image areas and water-receptive non-image areas. The surface is dampened and rolled with oil-based printing ink, then printed onto paper under pressure.
The image is not a raised relief or a network of ink-filled grooves. “Planographic” refers to this essentially flat printing surface. Prepared metal plates can also be used.
How etching works
In traditional line etching, a metal plate is covered with a protective ground. A needle exposes selected areas through that coating. A mordant bites the exposed metal; after preparation, the plate is inked and wiped, leaving ink in the recesses. Pressure transfers it to paper, usually dampened.
The chemical creates the recesses; ink creates the printed image. Etching is therefore intaglio, rather than relief printing. This is a process overview, not a chemical-bath recipe.
Is etching the same as engraving?
No. Both are intaglio techniques, but an engraver cuts directly into metal with a tool such as a burin. In etching, chemical action forms the recesses after the protective ground is opened.
Engraving involves controlling the cutting tool through the metal itself. Drawing through an etching ground offers a different working experience. A single artwork can combine techniques, so the categories are not always exclusive.
Can you identify a lithograph or etching by appearance?
An intaglio print often has a plate mark: an impression of the plate edge in the paper. This is a useful clue, but does not distinguish etching from engraving. Trimming can remove it, and reproductions can imitate the appearance of either process. Check the work’s catalogue entry or documented medium when identification matters.
How does offset printing relate to lithography?
Commercial offset lithography uses a plate, a rubber blanket and the printing substrate. The inked image transfers from the plate to the blanket, then to the paper. Traditional direct lithography prints from the stone or plate onto paper without that intermediate blanket.
In conventional wet offset printing, dampening solution helps keep non-image areas free of ink. Waterless offset uses a different non-image surface and does not use that dampening system. Neither should be confused with intaglio etching.
