Character set

A complete collection of the characters and symbols that constitute all the elements of a language or discipline (mathematics, for example), including punctuation and numbers, with a one-to-one correspondence to the ASCII codes 00-7F (hexadecimal). The printer uses these characters to determine its printing and nonprinting activities after it receives data from the host computer.

CMYK

Acronym for cyan, magenta, yellow, and black; the four colours used in the standard colour model of the printing industry. Refers to a method of specifying colour using CMYK colour values. (K is used for black because B is used to represent blue in RGB.)

CNG

Calling Tone. This is a signal sent by fax machines to identify the call as an incoming document. When the receiving fax detects this signal, it automatically starts to receive the fax transmission. The majority of fax machines in use today can send and detect CNG signals.
