Glossary
dot gain: An unavoidable increase in the size of halftone dots due to the interac-
tion of toner, paper, heat, and pressure during the printing process. This increase
in dot size increases the density of toner on paper, causing the printed output to
appear darker. GCC’s AccuGray technology works to counteract the effects of
dot gain.
dots per inch (dpi): A measurement of resolution, or the density of dots, for a
given output device.
download: To send a font to a printer’s built-in memory (RAM) or hard disk.
flow control: The control of information along an interface to enable the
interface to take only as much information as it can handle.
folder: An organization tool for arranging documents, applications, and other
folders on a storage device.
font: A collection of letters, numbers, punctuation marks, and special charac-
ters with consistent appearance.
Font/DA Mover: An application that allows you to change the screen fonts and
desk accessories in a System file. This application is used in versions of system
software prior to System 7.x.
grayscale: The range of gray tones between black and white.
halftone cell: A pattern of printer dots each of which can be turned on or off in
order to represent different percentages of gray.
halftone spot: A dot made up of smaller dots used to simulate continuous tone
photographs. The smaller dots are the printer dots which are printed at the
specified resolution. The pattern of the small printer dots is called a halftone
cell.
high-quality fonts: Outline fonts that are shipped with the printer or purchased
from your dealer. On the Macintosh, screen fonts are used to create your
documents and the printer replaces them with high-quality fonts during the
printing process. See outline fonts.
Installer: An application that installs the software.
interface: The point at which two devices are physically connected, enabling
them to communicate.
lpi: (lines per inch) A measure of the frequency of a halftone screen (usually
between 53 and 200). Lpi refers to the lines of halftone spots that make up the
screen.
