Monochrome printmaking is a generic term for any printmaking technique that produces only shades of a single color. While the term may include ordinary printing with only two colors — "ink" and "no ink" — it usually implies the ability to produce several intermediate colors between those two extremes.
A monochrome [1] or monochromatic image, object or palette is composed of one color (or values of one color). [2] Images using only shades of grey are called grayscale (typically digital) or black-and-white (typically analog).
The majority of monochrome photographs produced today are black-and-white, either from a gelatin silver process, or as digital photography. Other hues besides grey can be used to create monochrome photography, [1] but brown and sepia tones are the result of older processes like the albumen print, and cyan tones are the product of cyanotype prints.
William Friese-Greene (born William Edward Green, 7 September 1855 – 5 May 1921) was a prolific English inventor and professional photographer.He was known as a pioneer in the field of motion pictures, having devised a series of cameras between 1888–1891 and shot moving pictures with them in London.
The same print using sodium chloroplatinate will have cooler tones similar to those of a platinum/palladium print. The inherent low sensitivity of the process occurs because the ferric oxalate is sensitive to ultraviolet light only, thus specialized light sources must be used and exposure times are many times greater than those used in silver ...
Rather than printing multiple copies of a single image, only one impression may be produced, either by painting or making a collage on the block. Etching plates may also be inked in a way that is expressive and unique in the strict sense, in that the image cannot be reproduced exactly. [ 1 ]
Collotype is a gelatin-based photographic printing process invented by Alphonse Poitevin in 1855 to print images in a wide variety of tones without the need for halftone screens. [ 1 ] [ 2 ] The majority of collotypes were produced between the 1870s and 1920s. [ 3 ]
A method of full-color printing is six-color process printing (for example, Pantone's Hexachrome system) which adds orange and green to the traditional CMYK inks for a larger and more vibrant gamut, or color range. However, such alternate color systems still rely on color separation, halftoning and lithography to produce printed images.
