To avoid problems when using preprinted forms, embossed paper, and letterhead, observe
the following guidelines:
● Avoid using low-temperature inks (the kind used with some types of thermography).
● Use preprinted forms and letterhead paper that have been printed by offset lithography
or engraving.
● Use forms that have been created with heat-resistant inks that will not melt, vaporize, or
release undesirable emissions when heated to 205° C (401° F) for 0.1 second. Typically,
oxidation-set or oil-based inks meet this requirement.
● When the form is preprinted, be careful not to change the moisture content of the paper,
and do not use materials that change the paper's electrical or handling properties. Seal
the forms in moisture-proof wrap to prevent moisture changes during storage.
● Avoid processing preprinted forms that have a finish or coating.
● Avoid using heavily embossed or raised-letterhead papers.
● Avoid papers that have heavily textured surfaces.
● Avoid using offset powders or other materials that prevent printed forms from sticking
together.
