Engraving is a printmaking technique that involves carving a design into a metal plate using a burin or other sharp tool. The plate is then inked and printed, transferring the design to paper.

Nitric acid is the most commonly used chemical solution in etching. It is used to dissolve areas of a metal plate, creating the design.

Lithography is a printmaking technique that involves drawing a design on a flat stone or metal plate using a greasy crayon or tusche. The plate is then treated with water and ink, which adheres to the greasy areas of the plate and transfers the design to paper.

Screen printing is a printmaking technique that uses a stencil to transfer ink onto paper. The stencil is created by blocking out areas of a screen with a light-sensitive emulsion, which is then exposed to light. The exposed areas of the screen become hard and block the ink, while the unexposed areas remain soft and allow the ink to pass through.

Relief printing is a printmaking technique that involves carving a design into a wooden block and then inking and printing the block. The raised areas of the block transfer the ink to paper, while the carved areas remain blank.

Photogravure is a printmaking technique that involves transferring an image from a photographic negative onto a metal plate, which is then inked and printed. The plate is etched with acid to create a series of tiny cells that hold the ink, which is then transferred to paper.

Monotype is a printmaking technique that involves creating a unique, one-of-a-kind print by painting or drawing directly onto a metal or glass plate and then printing it. The plate is inked and then printed onto paper, transferring the image.

Pochoir is a printmaking technique that involves creating a design by cutting shapes out of paper or other materials and then arranging them on a flat surface, which is then inked and printed. The stencils are used to create multiple layers of color and texture.

Collograph is a printmaking technique that involves creating a design by pressing a textured object into a soft surface, such as clay or wax, and then inking and printing the resulting impression. The textured object transfers its texture to the soft surface, which is then inked and printed.

Drypoint is a printmaking technique that involves creating a design by scratching lines into a metal plate using a sharp tool, and then inking and printing the plate. The scratches create burrs on the plate, which hold the ink and transfer it to paper.

Aquatint is a printmaking technique that involves creating a design by sprinkling powdered rosin onto a heated metal plate and then melting the rosin to create a resist, which is then etched with acid and printed. The rosin creates a textured surface on the plate, which holds the ink and transfers it to paper.

Scraperboard is a printmaking technique that involves creating a design by scraping away areas of a metal plate using a sharp tool, and then inking and printing the plate. The scraped areas create a rough surface that holds the ink and transfers it to paper.

Offset lithography is a printmaking technique that involves creating a design by transferring ink from a metal plate to a rubber blanket and then to paper. The metal plate is etched with a design, which is then inked and transferred to the rubber blanket. The rubber blanket then transfers the ink to paper.

Lithography is a printmaking technique that involves creating a design by transferring ink from a metal plate to a stone or glass plate, and then to paper. The metal plate is etched with a design, which is then inked and transferred to the stone or glass plate. The stone or glass plate then transfers the ink to paper.

Woodcut is a printmaking technique that involves creating a design by transferring ink from a metal plate to a wooden block, and then to paper. The metal plate is etched with a design, which is then inked and transferred to the wooden block. The wooden block then transfers the ink to paper.
