Paper Guidelines

The terms below describe continuous form paper.

Terms And Definitions

Chaff

Residual bits of paper not completely 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 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.

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 region where printing occurs, and which is always
between the side perforations.

Print Station

The area in the printer where the actual impacts of printing
occur.

Staple

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.)

Tenting

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.

Tie Point

The area along a perforation between the cut points (see
above).
