Glossary
cue noise A false cue signal that results from some object or
imperfection on the substrate that the cue sensor detects or from
imperfections in the circuitry of the cue sensor. See also false cue.
cue sensor A sensor that detects the beginning of a mark on a web or
the leading edge of a piece of substrate.
cue window
expected.
An interval during which a signal from the cue sensor is
current font The font currently in effect. The font specified by the last
IJPDS record executed that contained a font identification field.
cursor A pointer in the page buffer. Cursor position is defined using X
and Y coordinates. See also cursor position, absolute cursor position, and
relative cursor position.
cursor position The current position of the cursor in the page buffer.
The cursor is set to the starting position by IJPDS position records, but is
moved by various other records such as SFI, IML, SPC, and BOX
according to the rules for the record. For example, when printing a line of
text, the starting position for the line remains the same, but the cursor
moves as each character is placed in the buffer. See also starting
position.
curtain The effect visible under a printhead when all ink jets are
operating and out of catch. The faint shimmering is produced by the ink
jets as they fall from the printhead.
dark defect A dark area in the image caused by allowing more than
one drop to fall for each dot or from allowing ink jets to release ink when
they should not. The dark defect can occur throughout the width of the
image, but it may be concentrated at the ends or near the center of the
image.
dark line A narrow line of ink that appears in half-tone images and
under certain conditions in text printing. The symptom results from an ink
jet that releases drops when it should not. The extra drops are released
when an adjacent ink jet is on, which indicates the charge circuits are
shorted together.
data station The module of the printing system that receives IPDS
jobs from the data source and that is used by an operator to control the
printing of the jobs.
DIP Data input processor. The part of the data station that receives
input data from the system controller, formats data using fonts and fixed
files loaded in memory, manages the data flow to the RIPs and other
processors, and tracks the printing of documents.
document A unit of input data that is printed in one area of the
substrate. A document may include more than one page. Most common
data preparation establishes one document for each cue mark on a web
or one document for each piece in cut-sheet printing. See also page.
document delay A measure of the distance from the first upstream
cue sensor to each downstream cue sensor.
dot 1. The smallest mark that can be printed by the printing system.
2. The distance between pixels (dots) in the printed image. With a 240-dpi
resolution, a distance of 1 dot equals 1/240 inch.
