Image Uniformity
The Xerox Nuvera™ 100/120/144
Digital Production System is designed
to render tints with a high degree of
uniformity, and produce vignettes,
sweeps and gradients that are smooth
and even.
Sophisticated design prevents
unwanted process speed variations
that plague lesser digital printing
systems with banding problems.
Halftoning algorithms and customized
halftone dot designs take full
advantage of the printer’s high
addressability imaging system to
render incredibly sharp, detailed
images.
The most discriminating judges
of print quality may occasionally
perceive a degree of mottle in
large uniform flat tints.
Extremely high humidity, low
document area coverage or
papers with poor formation can
exacerbate mottle.
If excellent uniformity is required,
controlling environmental factors
or an accelerated maintenance
rate can usually satisfy
demanding customers.
Text Quality
Black text quality is excellent for sizes as small
as 4 point.
Line Quality
The Xerox Nuvera™ 100/120/144 Digital
Production System can print solid lines all the
way down to 70 microns.
Area Coverage
The Xerox Nuvera™ 100/120/144
Digital Production System uses nested
automated controls of dry ink,
development, tone reproduction, and
the internal environment to assure
consistent printing. These closed loop
process controls continuously test
against the targets and adjust as
required.
The control system is designed to run
within a specific range of quality.
Although some variation may be
noticeable in specific cases, the closed
loop controls will typically deliver very
acceptable quality, consistently,
predictably, and without operator
intervention.
Mylar tabs
Images printed on Mylar tabs typically show
degradation due to toner scatter.
Other artifacts
As with any printing process, artifacts will occur
on the Xerox Nuvera™ 100/120/144 Digital
Production System. These include streaks,
mottle, banding, spots and edge deletions. For
most jobs and clients, the expected level of
artifacts is within the normal operational and
component quality ranges of the system and will
not affect the acceptability of the job.
Maintenance procedures are available
to mitigate these artifacts. Artifact-
sensitive jobs should be monitored.
Using stocks on the Recommended
Media List and maintaining your
environment will also help to minimize
the occurrence of these artifacts.
