Oil Paint

Oil paint consists of pigments mixed with linseed or poppy oil. This paint is applied to a canvas or panel with a brush or palette knife.

Gouache

Watercolor to which an opaque white, usually zinc white or titanium white, has been added. The paint gives a matt surface and is applied very thinly to prevent flaking.

Watercolor

Transparent, polychrome watercolor, made from finely ground, usually non-opaque pigments, also of vegetable origin. The paint is absorbed into the carrier, which is usually a white or slightly tinted rag paper. A watercolor is a direct painting done in a fast-drying watercolour, often on moistened paper. The ‘wet’ technique is based on quick reactions and short but concentrated work. 

Engraving

The engraving technique originates from silversmithing and is older than etching. It is based on a purely mechanical method, in which the engraver inserts, cuts or scratches a representation with a pointed object (burin) in a steel or copper plate. By varying the pressure during engraving, i.e. the depth of the cut, the differences in depth and width of the lines arise, and thus the tonal differences.

Due to the hardness of the material (copper or steel), the engraving is characterized by its somewhat angular character. Like the etching, the engraving is an example of intaglio printing. 

Sepia

Sepia is the black-brown dye, extracted from the ink of the squid, consisting mainly of melanin.

The sepia technique is a watercolor painting in brown or white using this dye.

Litho

Lithography or lithography is planographic printing, where the drawing to be printed and the printing surface lie in 1 plane.

This 18th century technique functions by virtue of the mutual repulsion of water and fat. A drawing is put on a polished limestone with grease chalk or ink. This fat absorbs into the stone and is treated with gum arabic.

The stone is wetted and rolled in with paint, which only adheres to the greasy spots where the drawing is.

The stone is then passed through the litho press and a printed paper is the result. The modern variant is photographic lithography, which is created by UV exposure on a light-sensitive plate on which an image has been placed.

Tempera

Italian Painting Technique in which protein or glue-bound colors are painted on a plaster or chalk substrate.

This technique was mainly used before the emergence of oil painting in the 15th century (eg panel painting in the Middle Ages).

The pure, non-glossy color substance in the tempera technique was made to shine in the Middle Ages by a layer of varnish, while today its matt surface, which is caused by the lack of oil, is appreciated.

Oliography

Printed matter, often a lithograph, which is provided with a layer of varnish, sometimes slightly browned, in order to obtain the effect of an oil painting.

Screen Printing

Screen printing is a carbon copy, comparable to stencilling.

The image is put on a transparent paper and placed on the screen coated with a lacquer. The whole is exposed to UV, so that the paint hardens in the places where light comes.

The unexposed lacquer, in the place where the representation is, remains soft and is washed out.

When paper is placed under the sieve and the paint is pulled from one side of the sieve to the other with a puller, the paint pushes through on the open slices and reproduces the image on the paper.

Wood Cut

This is relief printing, from the printing plate, wood or linoleum, the negative of the image is cut, so that the drawing itself is saved. The printing plane of the drawing is therefore higher than the rest. (as a stamp).

The high parts are rolled in with ink and printed by pressing a paper force on them. Colored paper can be used, but also colored ink.

Linolum Cut

Similar to woodcut. However, this is done on Linoleum.

Maroufle

Name for an oil painting, in which a paper or linen canvas is glued to a wooden panel.

If a canvas is damaged by means of tears or holes, this canvas is often marouflaged by the restorer, ie glued to a wooden panel, making the tears or holes easier to repair. This repair method is also used if there is a lot of open Crackle.

Pastel

Pastels are powdered paints, mixed with water and lime, or oil and lime, which have been pressed into sticks. Sometimes a binding agent is added to this to prevent crumbling.

Pastels are usually applied to Ïngres” paper.
