Preprinted
Forms
During the print operation, heat applied to preprinted
forms can remove ink from the form and leave
residue (called offset) inside the printer.
In addition to offset residue problems, ink residues
may generate harmful gases and emissions. Note the
following considerations.
Forms should be printed with heat-resistant inks
that do not vaporize or generate harmful emis-
sions at temperatures greater than 200˚C (392˚F)
for 0.1 seconds.
Don’t use paper printed with low-temperature
inks.
Inks must not be flammable.
Inks must not be affected by the resin compo-
nents found in toner.
Care must be taken to avoid changing the mois-
ture content of paper being preprinted or using
materials that change the electrical or handling
properties of the paper. Forms should be sealed
in moisture-proof wrapping after preprinting to
prevent moisture changes during storage.
