The separation of multi-coloured original art by camera or laser scan techniques to produce individual negatives for each separated colours. The four common separations: yellow, magenta (red), cyan (blue) plus black are required for full-colour (four-colour) printing.
A process of converting full-colour images into a limited number of primary colors. Additive primary colours (red, green and blue) are used by the scanner, and the subtractive primary colours (cyan, magenta and yellow) plus black are used for printing press colour separation.
Film intermediates made from the colour originals to determine and reproduce the proportional amount of cyan, magenta, yellow and black in the original. These films are used to produce printing plates for each colour.
1. Technique of using a camera, scanner or computer to divide continuous-tone colour images into four halftone negatives. 2. The product resulting from colour separating and subsequent four-colour process printing. *Also called separation.
In colour reproduction , the process of separating the various original colours of an image by a colour filters in a camera or electronic scanner so that the colour separation film and then printing plates can be produced.
(1) The mechanical and hand process of separating artwork destined to be coloured into negative overlays or components for each of the printing colours; (2) The optical process of separating coloured artwork by means of colour filters into separate single-colour negatives for each of the subtractive primary colours.
The production of a separate printing plate for each ink colour that will be used to print an image. Four plates are used in process colour separation, one each for Cyan, Magenta, Yellow, and Black. An addition plate is used for each spot colour.
The division of a multi-coloured original or line copy into the basic (or primary) process colours of yellow, magenta, cyan and black. These should not be confused with the optical primaries: red, green and blue.
