Printmaking is done using a wide variety of materials and techniques. Below, Magno explains the four basic printing processes:

In relief printing, ink is applied on the surface of the matrix, which is transferred on the final ground. For example, in woodcut and rubbercut, the design is drawn on a piece of wood or rubber. The background or non-printing area is cut away with a carving tool. Using a roller, ink is then applied to the matrix which is pressed on the paper, fabric or other surfaces. Designs produced in this process are usually very bold and raw. All you need is ink, a roller, and usually a spatula for rubbing and transferring the image from matrix to paper.

In the intaglio process, scratches and incisions are made into a plate or matrix. The plate is usually made of copper, zinc or an acrylic sheet, which holds the ink or pigment. The artist pushes the ink with a squeegee onto the entire plate and wipes off the excess ink on the surface, leaving the ink only in the incised lines. A damp sheet of paper is placed on top of the plate and the plate is run through the etching press, which pushes the paper into the groves, lifting the ink out of the groves. Drypoint, etching, engraving, mezzotint and aquatint are some techniques under the intaglio process. In contrast to the relief method, the images produced in etching are more fluid and spontaneous.

The planographic technique pertains to lithography. It is based on the principle that oil and water repel each other, and limestones are naturally attracted to oil. In handmade lithographs, the artist draws or paints directly onto the limestone with a greasy lithographic pencil or touché. It is then treated with acid accordingly and the ink adheres only on the drawn areas when rolled on. Soft lines and varied tones are achieved from lithographs.

Serigraphy is also known as the silkscreen process, a method also used in shirt printing. In contemporary silkscreen, artists use screens made of a fine nylon or polyester mesh. Selected areas of the screen are blocked out by screen fillers or paper stencils, and the ink is prevented from penetrating through the mesh to the paper or textile underneath. Serigraphy is most favoured by artists who use a lot of color in their works.
