Glossary

catcher bottom plate The component of the catcher plate that
contains a row of electric leads that control drops of ink. When a charge
lead is activated, it imparts a charge to the ink drop that causes the ink
drop to be attracted to the catcher. When a lead remains deactivated, the
drop of ink remains uncharged and falls to the substrate.
charge voltage A parameter in the system software that determines
the voltage applied to the printhead, which charges drops of ink, attracting
them to the catcher or leaving them uncharged so that they hit the
substrate. (Also called printhead volts or volts.)
charge phase The parameter in the system software that determines
when the charge voltage is applied to the printhead. Charge phase is
measured in counts. (Also called printhead phase or phase.)
cue A signal that represents the start of a document. A cue signal
occurs each time the cue sensor detects the leading edge of a piece of
substrate or a pre-printed cue mark on the substrate.
cue delay The distance from the leading edge of a piece to the start of
the image.
cue distance The distance from the cue sensor to the print array.
cue error A parameter in the system software that allows the operator
to determine how a cue or piece overrun error is handled.
cue mark A pre-printed mark on a web that, in most cases, indicates
the start of a new document.
cue sensor A device mounted on the document transport that detects
the beginning of a document. The beginning can be indicated by marks
on a web or the leading edges of pieces of substrate.
distortion A printing problem characterized by wavy or irregular
characters that occurs when the printhead is positioned too far away from
the substrate.
document A complete image as defined in the input data. A document
may include more than one page of data. Most common data preparation
establishes one document for each cue mark on a web.
document transport A device used to move the substrate or pieces
during printing.
dot 1. The smallest mark that can be printed by the printing system.
2. A unit of measure related to the resolution of the printhead and tach
encoder. For example, at 120-dpi resolution, a distance of one dot equals
/120 in.
