A positive is, obviously, the opposite of a negative – that is, it is an image which is not reversed. Positive images are made through a double negative: silver salts react to light producing a negative which, when projected onto photographic paper (more silver salts), produces a positive.
A particular type of reversal (R-type) colour paper and printing process which gives strong colours (often with striking reds) and creates a long-lasting print. Printing in this way from a positive image results in exactly the same colour saturation as the original, and greater contrast.
Toning, or toned black and white: toning images allows an artist/printer to alter the colours of a photographic print (by replacing the silver in the silver salts with another metal). Toning can be used as an aesthetic decision by the artist, or it can also be used to improve the archival properties of a print….
A stencil is made up for each colour of the image and put over a fine fabric mesh that is stretched over a metal frame. The coloured ink is spread over the mesh and stencil and the ink falls through the stencil to the underlying material (usually an art paper) to produce the image. The…
Pigment, unlike dye, is a powder made up of tiny granules that will not dissolve completely in solution. This means that pigment-based inks leave particles of pure colour bonded to the surface of the paper that they are printed on. The resulting images can thus appear very rich and physical, densely saturated in colour –…
Digital printing that produces images directly on to the material (e.g. canvas or special paper surfaces) from a digital file through a stream of very fine dye drops controlled by the computer system. (See also Giclée prints)
