Label design guidelines
Dual web forms
Constructing dual web forms involves joining together rolls of two different materials (usually pressure-sensitive paper and
bond paper) and then converting to a cut sheet product. This construction requires a stripped edge matrix. The liner must
be rigid enough to withstand the pick force of the printer.
The two materials must be thin enough for the sheet to lie flat in the paper tray. Orient the form in the tray so that the
pressure-sensitive area feeds into the printer first. The form should have no adhesive exposed in the overlay area or
anywhere along the front or back of the form. We recommend designing a non-adhesive strip with a minimum width of
1 mm (0.04 in.) along the edges of the overlay.
To help prevent material from slipping in the fuser, we recommend
knurling
, which roughens up the exposed silicon area at
the glue joint.
See
Figure 5 on page 20
for an illustration of the recommended dual web form design. The Non-print area may vary,
depending on the printer model.
The face sheet of a dual web form is usually a paper pressure-sensitive product; therefore, the guidelines for paper labels
are applicable to dual web forms.
