Appendix B Paper Guidelines
Methods Of Forms Attachment
Any method of attachment (staples, crimps, gluing, etc.) must be designed in
a way that does not permit air to be trapped between copies of a form. Hard or
wire brads and staples must not be used.
Any attachment must not coincide with the major perforation or any horizontal
perforation.
Gluing
Gluing must be controlled and uniform, since it is a major contributor to the
maximum form thickness. A form that meets the maximum forms thickness
requirement in the print area but which exceeds the maximum thickness at a
glue line is considered an unreliable and unpredictable form.
Staples
Staples must be used only in the margin area of the form and must not be in
line with the path of the tractor holes. Ideally, staples are placed in the
margins so that they coincide with areas of the form where printing does not
occur.
The figure below shows acceptable and unacceptable ways of fabricating
staples.
