Form Evenness
The evenness of the form = ________
(Not to exceed 0.003 in. / 0.00762 cm)
Tenting due to buildup of perforation thickness must be minimized. A
perforation thickness measured at the major perforation that exceeds 1.25
times the forms thickness measured in the print area will result in an
unreliable and unpredictable form. Perforation thickness must not exceed the
maximum form thickness of 0.025 in. / 0.0635 cm.
Tractor Pin Holes
The holes which engage the tractor pins must conform to the following
specifications:
Methods Of Forms Attachment
________ Must not allow air entrapment between copies of the form
________ Must not use hard brads or staples
________ Must not coincide with major perforation or any horizontal
perforation
________ Gluing lines must not result in a form that exceeds 0.025 in. /
0.0635 cm thickness
________ Staples must be used only in margin area of form
________ Staple cuts must not be in the direction of form movement
through the tractors
________ Staples must not occur in-line with the path of the tractor holes
________ Staples should be placed in the margins so that they coincide
with areas of the form where printing will not occur
