Paper Guidelines - Printronix P7000 Series Maintenance Manual

Test the paper first if it will be used in environments with greater than 80% or
less than 20% humidity. Test paper that will be used at high humidity for
satisfactory feeding and handling. Test paper that will be used at low humidity
to determine if static buildup must be eliminated for proper paper stacking.

Tie Point
Bits of paper not completely removed after the punch
process that creates tractor pin holes, major and minor
perforations, etc.
The area along a perforation where a cut has been made
that extends through the entire form. (Compare Tie Point.)
The ratio of cut points to tie points occurring along a
perforation.
The amount of variation between the thickest and thinnest
points measured across the print area (i.e., between the
side perforations).
Thickness measured at the thickest point of the entire
form. This includes glue lines, compressed staples,
perforations, etc., and is not limited to the printed region of
the form.
The region outside the print area of the form. The margin is
typically bounded by the outermost vertical perforations
(i.e., where the tractor holes are located) and the edge of
the form.
The region where printing occurs, and which is always
between the side perforations.
The area in the printer where occur the actual impacts that
constitute printing.
A punch-cut fastening stitch located along the vertical edge
and within the side perforation region of a multipart form.
(Note that this is not a metal staple.)
The measured thickness between the print area of the form
and the peak thickness of a major perforation. Tenting is
typically caused by overly stiff perforations or incorrect
registration of the inner parts of multipart forms.
The area along a perforation between the cut points.
(Compare Cut Point.)
