Etching
Etching lets an artist draw relatively freely on a coated metal plate, then uses a mordant to bite the exposed lines. The printed image comes from ink held in those recessed grooves under press pressure.
Etching versus engraving
Both etching and engraving are intaglio processes, but the line enters the plate differently.
In engraving, a burin cuts the metal directly and the resistance of the plate shapes the stroke. In etching, the plate is covered with an acid-resistant ground and the artist draws through that coating with a needle, exposing metal without having to carve it deeply. A mordant then bites the exposed lines. This makes etched drawing feel closer to pen work, although the bitten plate and press still impose their own technical constraints.

Plate, ground and bitten line
Copper was historically common, while zinc and other metals have also been used. The ground can record very fine needle movement. When the plate is exposed to a suitable mordant under controlled studio conditions, longer biting generally creates deeper lines capable of holding more ink. Artists can protect some lines and continue biting others to create several depths. Historical chemical processes involve hazardous materials, so contemporary printmaking should use current workshop procedures rather than copied old formulas.
Printing the plate
After the plate is prepared, intaglio ink is worked into the recessed lines and much of the surface ink is wiped away. Dampened paper is forced into the grooves under high pressure on an etching press, pulling ink from below the surface. This pressure leaves a plate mark around many impressions. Wiping itself affects tone: a printer can clean the surface heavily or leave a film of plate tone. Two impressions from the same plate can therefore differ even before deliberate changes of state.
Rembrandt and states
Rembrandt used etching together with drypoint and engraving, revising plates substantially between printings. The Three Crosses is famous for states in which changes to shadow and line alter the entire dramatic structure. A print 'state' records a particular condition of the plate after changes. Collectors often distinguish states because they document process and can be much rarer than later impressions. Etching therefore supports an iterative working method closer to repeated revision than to one final immutable matrix.
Etching, aquatint and later practice
Aquatint is a related intaglio technique designed to produce broader tonal areas rather than linear grooves alone. Artists such as Goya combined etched line with aquatint in series including Los Caprichos. Modern printmakers also combine etching with soft-ground, drypoint and photographic processes. Calling all acid-processed intaglio 'etching' can hide these differences. The useful question is which parts of the image come from line, tone, direct scratching or other plate treatments.
More context, examples and technical detail
This section moves beyond the introductory account into the material, historical and interpretive details that make Etching worth studying in depth.
Acid draws the line into metal
In etching, a metal plate is covered with an acid-resistant ground. The artist scratches through the ground with a needle, exposing metal where lines are wanted, and acid then bites those lines below the surface. Ink is worked into the recessed marks and wiped from the plate before printing under pressure. Because the needle moves through soft ground rather than carving metal directly, etched lines can feel freer and more drawing-like than burin engraving.
Multiple bites, stopping-out and different acid strengths allow lines of varied depth.
Rembrandt made the printed plate a changing artwork
Rembrandt exploited etching together with drypoint and engraving, revising plates across different states. He sometimes left plate tone or deliberately varied wiping so individual impressions from the same plate differed. This practice complicates the idea that prints are mechanically identical multiples. Collectors often distinguish states and impressions because changes in burr, ink and wiping alter the image significantly.
Acid replaces the burin as the drawing instrument
In etching, a metal plate is covered with an acid-resistant ground and the artist draws through that ground with a needle. Acid bites the exposed lines into the metal, which can then hold ink for printing. Because the needle moves through a soft coating rather than cutting metal directly, etched lines can feel freer than engraved ones. Artists vary line strength by changing biting time, stopping out areas and combining techniques such as drypoint or aquatint. Rembrandt exploited repeated states and selective wiping to make individual impressions differ dramatically. Etching therefore sits between drawing, chemistry and the mechanical pressure of the printing press.
