Using Your Printer
adhesives are semi-liquid and may contain volatile components
that can cause printer contamination or fumes when the adhesive
is heated or placed under pressure.
Zone coating (or zone printing) of the adhesive involves placing the
adhesive only where needed. Zone coating is generally used with
paper labels and integrated forms. A no-adhesive border of 1 mm
(0.04 in.) around the outside edge of the label sheet generally gives
good results. Check with your forms supplier to determine
whether selected labels are appropriate for your printer.
A stripped edge matrix of 3 mm (0.125 in.) along the outer border of
the label sheet, combined with a tight adhering adhesive that does
not ooze, may prevent glue contamination. This design requires a
stiffer backing material to prevent crushing when the sheet is
aligned on the reference edge. Generally, vinyl and polyester labels
lend themselves to this design with few problems. Paper and dual-
web designs require some testing to determine which backing
produces good results.
Finally, make sure that the adhesive has pull strength adequate to
prevent label peeling during printing. Adhesives must be able to
withstand pressure of 25 psi and fuser temperatures of 212°C
(414°F) without creating hazardous fumes or oozing from edges of
labels or die-cuts. Contact your forms supplier for additional
information.
Face Sheet (Printable Stock)
Paper, vinyl, and polyester are the major printable stocks used for
labels. When using alternate face sheets, your forms supplier can
provide information on whether the stock face can withstand
temperatures of 212°C (414°F) and pressure of 25 psi. You should
test the stock to ensure it works satisfactorily with your printer.
