Basis Weight s and
Gram m age
In North America, the
customary or commercial
term for expressing the
weight per unit area of paper
is “basis weight.” In most
other
countries,
the
commercial term used for
paper weights is grams per
square meter for all paper
types.
Basis weight is defined as
the weight in pounds of a
500 sheet ream of a
particular area depending on
the type of paper (i.e., Bond,
text/offset, cover, index,
bristol, etc.). Each paper
type is rated on a different
size/area:
•
Writing and printing:
17”x22”
•
Cover: 20”x26”
•
Book/ Offset: 25”x38”
•
Index: 25.5”x30.5”
•
Bristol and tag:
22.5”x28.5”
•
Cardboard: 22”x28”
The DocuColor 8000 / 7000
requires a gram per square
meter (gsm) input for paper
weight to adjust and optimize
image quality.
To
make
the
correct
selection, customers should
use the converting table on
the previous page and in the
Operator Manual
to match
the equivalent weight across
the different categories and
paper types.
For example, a 20-pound
xerographic bond paper
weighs close to 75 gsm as
does 50-pound offset/book.
Sm oot hness/Finishes
Customers
should
use
smooth or coated finishes for
documents that have fine
detail, shaded areas, or
halftone images.
Form at ion
Formation is determined by
the degree of uniformity of
the distribution of the fibers
in the sheet.
Poor fiber formation can
cause mottle or uneven
toner distribution in images
with
high
solid
area
coverage. To learn more
about the formation of a
paper, hold a sample sheet
up to a light, the paper is
well-formed if it looks even
and consistent throughout
the sheet.
Customers should choose
well-formed sheets or coated
materials when printing high
coverage jobs.
Bright ness
When toner is applied to
brighter papers, images have
heavier
contrast
which
improves printability and
quality. For the best results,
customers
should
use
brighter papers for jobs that
contain complex graphics or
photos.
