Glossary
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
during printing.
dot 1. The smallest mark that can be printed by the printer.
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.
1
downstream In a multiple printer configuration, the last printer to print.
dpi Dots per inch, a measure of print resolution.
drop interference A printing problem characterized by a ragged line of
print or scattered dots, which indicate an interference with the flight of
drops. Drop interference is usually caused by particles of dust adhering to
the printhead bottom cover. Drop interference may also be caused by
dust adhering to the eyelid or to the inside of the printhead assembly.
elongation A printing problem characterized by elongated characters
that occurs when the parameters set for tach and cue are incorrect or the
tach encoder is incorrectly tracking the substrate speed.
extra dots A printing problem characterized by extra drops of ink,
which occurs when the charge voltage is too high.
eyelid The part of the printhead that opens to allow uncharged drops to
fall to the substrate. When closed, the eyelid protects the interior of the
printhead from damage and dust and seals the printhead during power-on
and power-off to prevent fluid leakage.
feedstroke A measurement used in multiple printer configurations to
determine where an image is printed on the substrate. Feedstroke equals
the piece length plus the distance between pieces.
filament A short, continuous stream of ink extending from the orifice,
which is broken into drops by the measured application of a physical
vibration.
A device used to move the substrate or pieces
