Paper Guidelines

The terms below are used to describe and discuss continuous form paper.
(See also Figure 100.)

Terms And Definitions

Chaff
Cut Point
Cut-to-Tie Ratio
Evenness
Form Thickness
Margin
Print Area
Print Station
Staple
Tenting
Tie Point
Residual 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.
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 the actual impacts that
constitute printing occur.
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 (see
above).
