Acrylic paint is a fast-drying paint made of pigment suspended in acrylic polymer emulsion. Acrylic paints are water-soluble, but become water-resistant when dry. Depending on how much the paint is diluted with water, or modified with acrylic gels, media, or pastes, the finished acrylic painting can resemble a watercolour or an oil painting, or have its own unique characteristics not attainable with other media. Oil paint takes many days to dry, so Jonathan finds acrylic paint much better for plein air painting.
Monotypes, or monoprints is a print where a single impression of an image is made from a reprintable block. Materials such as gel, glass, perspex or metal plates, litho stones or wood blocks are used for etching. Rather than printing multiple copies of a single image, only one impression is produced (or a second ‘ghost’ image), either by painting or making a collage on the block. Monoprints may include collage, hand-painted additions, and a form of tracing by which thick ink is laid down on a table, paper is placed on top and is then drawn on, transferring the ink onto the paper.
Chine-collé is a special technique in printmaking, in which the image is transferred to a surface that is bonded to a heavier support in the printing process. One purpose is to allow the printmaker to print on a much more delicate surface, such as Japanese paper or linen, which pulls finer details off the plate. Another purpose is to provide a background colour behind the image that is different from the surrounding backing sheet.
Drypoint is a printmaking technique of the intaglio family, in which an image is incised into a plate (or ‘matrix’) with a hard-pointed ‘needle’ of sharp metal or diamond point. Traditionally the plate was copper, but now acetate, zinc, plexiglas or special card plates are also commonly used.
