Intaglio printing is a printmaking and security-printing process where the image is cut or etched into a plate, and those recessed lines hold the ink that prints the design.

What is intaglio printing?

Intaglio (from Italian intagliare , “to engrave”) is a group of techniques in which an artist or printer incises an image into a metal plate—traditionally copper or zinc—and the sunken lines, not the surface, carry the ink. It is the opposite of relief printing, where the raised surface prints and the recessed areas stay blank.

In practice, the plate is inked all over, then carefully wiped so ink remains only in the grooves. Damp paper is laid on top and both plate and paper are run through a high‑pressure press, forcing the paper into the ink‑filled recesses to pick up the image.

Key steps in the intaglio process

  1. Prepare the plate
    A smooth metal plate (often copper, zinc, or nickel) is polished and sometimes coated with a protective ground.
  1. Create the image
    • Engraving with a burin directly into the metal.
    • Etching using acid to bite lines where a resist has been scratched away.
    • Drypoint, aquatint, and mezzotint for softer lines and tonal effects.
  1. Inking
    The plate is covered with ink, pushing pigment into every incised line and pit.
  1. Wiping
    The surface is wiped clean—often with tarlatan cloth and paper—so only the recessed areas still hold ink.
  1. Printing
    Damp paper is placed on the plate and run through a roller press under several tons of pressure. The paper is pressed into the grooves, picking up ink and leaving a rich, slightly embossed impression and a characteristic “platemark” around the image.

Common intaglio techniques

  • Engraving – Sharp, clean lines cut with a burin; often used historically for detailed illustrations and maps.
  • Etching – Lines bitten by acid, allowing freer, more spontaneous drawing in the ground.
  • Drypoint – Scratched lines that leave a burr, creating soft, velvety marks.
  • Aquatint – Grainy, tonal areas rather than lines, ideal for shaded passages.
  • Mezzotint – Rich darks and subtle gradations, produced by roughening then selectively smoothing the plate.

All of these can be combined on one plate to get intricate detail and nuanced tones.

Where you encounter intaglio today

Historically, intaglio dominated artistic and commercial printmaking in Europe from the mid‑16th century until the 19th century. Today, it survives both as a fine‑art medium and as a high‑security printing method.

  • Fine art prints
    Artists and print studios still use copper and zinc plates, hand inking, and presses to produce limited‑edition etchings and engravings prized for their depth and tactile quality.
  • Security printing (like money)
    Many banknotes and secure documents use intaglio on steel or nickel plates. The heavy pressure deposits thick layers of ink, yielding a raised, tactile surface and ultra‑fine detail that is hard to copy with standard printing. Features include raised microtext and latent images that appear when you tilt the print in light.

Mini FAQ and quick scoop

  • Is intaglio the same as etching?
    No. Intaglio is the broader family; etching is just one technique within it.
  • How can I spot an intaglio print?
    Look for a visible platemark around the image and a slight relief you can feel with your fingertips, especially in darker inked areas.
  • Why do artists still use it?
    It offers very fine lines, deep tones, and a distinctive, physical impression in the paper that digital methods can’t quite replicate.

TL;DR: Intaglio printing is a traditional printmaking and security‑printing method where an image is cut into a plate, the recessed lines hold the ink, and high pressure transfers a richly detailed, slightly raised image to paper.
