Terms and Definitions 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. Paper Guidelines The terms below are used to describe and discuss 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 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 ThicknessThickness 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 that constitute 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). 299
