HP LQH-HW 3ULQWHUV manual Paper Guidelines, Terms And Definitions

Terms And Definitions

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

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).
