Heavy-Weight Papers

COLOR MATERIALS USAGE GUIDE
USAGE GUIDELINES FOR XEROX COLOR COPIERS AND PRINTERS
Contact your Xerox representative or visit the Xerox website for the
current list of recommended materials for your copier/printer.

Description and expectations

Heavy-weight papers can be classified as different weights of paper
for different machines. Always refer to the user guide for your copier/
printer for the weight range of heavy-weight papers acceptable for
that machine.
Compared to the benchmark 24 lb (90 g/m
papers offer increased stiffness and as a result, must be run from a
designated tray. The Recommended Materials List for your product
will provide the name, or number, of this tray. As paper weight and
stiffness increases, the likelihood of jams also increases. The
possibility of image mottle also increases because of the rough
surface and coarse formation of the paper.
Two-sided copying of heavyweight paper may not be recommended
for your copier/printer because of increased jams and degraded
image quality on the second side. Refer to the Recommended
Materials List for your machine for information on the paper weight
limit for two-sided copying.

Hints, tips and testing results

Extensive Xerox testing has shown the following:
•
When the recommended heavy weight papers are run as
recommended, with the correct tray, mode, orientation and
curl, feeding performance is good but should not be expected
to equal that of 24 lb (90 g/m
•
Image quality on the recommended papers is good, but should
not be expected to equal image quality on 24 lb (90 g/m
Color Xpressions paper. Image quality degradation is more
likely to occur as paper weight increases. The rough formation
of heavy papers increases the likelihood of mottle (light
patches) with some images. Mottle is more likely to occur on
images with uniform halftone areas. As humidity increases,
mottle usually increases.
•
Dry ink coverage/saturation on electronic originals should be
adjusted through various settings in application software and/
or the Digital Front End (DFE)/Raster Image Processor (RIP)
to optimize the output quality. Higher dry ink coverage can
result in poorly fused prints. In some cases, customers might
need to set copy quality to a lower density level. The DFE/RIP
color calibration procedure should be performed regularly for
color intense print jobs.
