The terms below describe continuous form paper.

Terms And Definitions

Chaff Residual bits of paper not completel y removed after the
punch process that creates tractor pin holes, major and
minor perforations, etc.
Cut Point The area along a perforation where a cut has been made
that extends through the entire form.
Cut-to-Tie Ratio The ratio of cut points to tie points occurring along a
perforation.
Evenness The amount of variation between the thickest and thinnest
points measured across the print area (i.e., between the
side perforations).
Form Thickness Thickness measured at the thick est point of the entire form.
This includes glue lines, compressed staples, perforations,
etc., and is not limited to the printed region of the form.
Margin 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.
Print Area The regio n where printing occurs, and which is always
between the side perforations.
Print Station The a rea in the printer where the actual impacts of printing
occur.
Staple A punch-cut faste ning stitch located along the vertical edge
and within the side perforation region of a multipart form.
(Note that this is not a metal staple.)
Tenting The measured thicknes s 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.
Tie Point The area along a perforation between the cut points (see
above).
