Collate copies - The feature of most print management programs which sends one page
after another to the printer. Note: must be turned off to prevent creating a new
master for each copy printed.
Color separations - Individual, single-color images used to create a full-color printed
image with a multiple-pass printing process. Colors typically used are CMYK.
Configuration Utility - The program used to manage printing tasks on a digital
duplicator.
Connectivity - The term used to describe the physical methods for connecting the
controller to a computer.
CPU - Central Processing Unit – the instruction execution and data processing
component of the computer hardware.
Daisy Chain - A method described by serially connecting together several devices.
Peripheral devices that use a SCSI port, such as a CDROM, hard disk and scanner,
can be daisy chained to one SCSI port of a computer.
Diagnostic Test Page - Generated by the controller in response to the corresponding
button on the back panel being pushed. It displays the controller’s internal settings.
Dialog Box - A pop-up window in some programs used to get information from the user
before proceeding with some task.
Digital Duplicator - A duplication device that takes electronic images from a scanner or
controller, creates a master of the image, and produces copies of that image on plain
paper.
DIMM - Dual Inline Memory Module, a type of RAM configuration
DIP Switch - A switch in DIP (Dual Inline Pin) configuration, usually located on a
circuit board of a device.
DOS - Disk Operating System – a non-graphical line-oriented command-driven single-
task program that provides application software access to computer BIOS functions,
primarily the disk drives.
Dot Gain - Describes the result when ink spreads a small amount on the paper after
passing through the holes in the master, to ultimately become bigger than the original
hole.
Download - The process of moving software or data from one location (e.g., an FTP site
on the Internet) to another (e.g., your computer).
DPI - Dots Per Inch – dots are the smallest printable units by a printer. Thus, DPI is the
resolution specification of a printer or screen communicating the graininess of the
resulting image.
DPI Resolution - The specification relating to the image quality of the printer or screen
display. Generally, the higher the DPI rating, the better the image, and the more
memory the product must use to create the image.
DRAM - Dynamic-refresh Random Access Memory - a type of RAM IC that uses solid
state capacitor elements requiring continuous refresh to store information.
