•
Stiffness – Stiffness refers to the rigidity, or bending
resistance of paper. Thicker papers are usually stiffer.
Usually, reliable feeding rates can be obtained by feeding
lightweight paper with the grain direction the same as the feed
direction. This will increase the stiffness. When feeding 32 lb
xerographic/bond or heavier paper, the grain direction should
be the opposite of the feed direction to decrease stiffness.
•
Porosity – Paper that is too porous causes misfeeds or
multifeeds as well as solid area mottle (spotty or uneven
printing) and smears. Low porosity (denser) sheets tend to
have more curl and are prone to image smears.
•
Weight – Weight is another important consideration. Heavier
sheets are often thicker because they contain more fibers.
These papers may be too thick or rigid to pass through the
paper path of certain printers. They may also crack or blister
when folded (even when scored).
Hint: When choosing paper, select
stocks that are within
recommended range for the
print technology being used.
Test the paper by folding a
sample document.
Binderies score thick papers
before folding, especially coated
stocks, or when heavy ink coverage
will cross a fold.
