Unfortunately, different operating systems use different character sets. So a character that can be used on a Macintosh may not be present in the character set of a Windows computer or vice versa.

– A technique to reduce the amount of data in a color image file by removing large amounts of redundant data.
A deliberate change of certain colors in the original when it is reproduced. The customer may have requested the modification, or it may be needed because of the colorants that were used to reproduce the image.

The changes can be made electronically, photographically, or manually so that the separation films produce the desired result.
The complete range of hues and strengths of colors that can be achieved with a given set of colorants such as cyan, magenta, yellow and black ink printed on a given paper and given printing press. Although it can represent strength, it usually represents hues.

The process of making a separate electronic or photographic record of the amounts of each process color of cyan, magenta, yellow or black needed to reproduce an original copy. The record may be a photographic film made through red, green and blue separation filters or a computer file. A set of four separations, cyan, magenta, yellow and black, are required to reproduce an original color image since each of the four process colors must be represented. The separations may be made photographically using traditional methods or digitally using scanners and software. The original copy may be a transparency, reflection photographic print, drawing, painting, or printed reproduction.
On a printing press or color proof, the order of applying the yellow, magenta, cyan, and black inks to the substrate.

Marks on a final printed sheet that indicate the trim lines or register indicators.
In typography, an enclosed area within a letter. Also called the aperture. The small dot in the ‘e’ character is a counter.
Courier was originally a typeface that was designed for the IBM Selectric typewriters. It is a typical fixed pitch design, monotone in weight and slab serif in concept. On computers, it is used to emulate typewriter output for reports, tabular work, and technical documentation. Many output systems use Courier as a substitution font when fonts are missing in a document or on a system. This explains its ‘popularity’ in prepress.

4 thoughts on “C – ‘C1S’ to ‘cyan’”
what s the abbreviation for the density measurement, of the CMYK mixing to produce black color? its about the measure that you must not exceed or you will have a lot amount of ink in some shadow printing areas
