C-41 is a chromogenic color print film developing process introduced by Kodak in 1972, [1] superseding the C-22 process.C-41, also known as CN-16 by Fuji, CNK-4 by Konica, and AP-70 by AGFA, is the most popular film process in use, with most, if not all photofinishing labs devoting at least one machine to this development process.
4-colour mezzotint of Louis XV by Le Blon, 1739 Page from Le Blon's 1725 Coloritto describing his RYB three-color printing process [1]. Jacob Christoph Le Blon, or Jakob Christoffel Le Blon, (2 May 1667 – 16 May 1741) was a painter and engraver from Frankfurt who invented a halftone color printing system with three and four copper dyes using an RYB color model, which served as the foundation ...
A chromogenic print, also known as a C-print or C-type print, [1] a silver halide print, [2] or a dye coupler print, [3] is a photographic print made from a color negative, transparency or digital image, and developed using a chromogenic process. [4]
In intaglio printing, the lines to be printed are cut into a metal (e.g. copper) plate by means either of a cutting tool called a burin, held in the hand – in which case the process is called engraving; or through the corrosive action of acid – in which case the process is known as etching.
Before final printing, the image is proof printed and any errors corrected. In the direct form of printing, the inked image is transferred under pressure onto a sheet of paper using a flat-bed press. The offset indirect method uses a rubber-covered cylinder that transfers the image from the printing surface to the paper. Colours may be ...
However, from 1880 to 1950 a photo-mechanical ("line-block") variant was the dominant form of commercial printing for images. A similar process to etching, but printed as a relief print, so it is the "white" background areas which are exposed to the acid, and the areas to print "black" which are covered with ground. Blake's exact technique ...
Reduction printing is a name used to describe the process of using one block to print several layers of color on one print. Both woodcuts and linocuts can employ reduction printing. This usually involves cutting a small amount of the block away, and then printing the block many times over on different sheets before washing the block, cutting ...
In computing, blue paint refers to the mark given to preprocessing tokens by the C preprocessor that temporarily disables expansion of those tokens. A token is said to be painted blue when it has been disabled in this way.
