Use these guidelines when selecting preprinted forms and letterhead:
- Use grain long for 60 to 90
g/m2 (16 to 24
lb) weight paper.
- Use only forms and letterhead printed using an offset lithographic or engraved printing process.
- Avoid papers with rough or heavily textured surfaces.
Use papers printed with heat‑resistant inks designed for use in xerographic copiers. The ink must be able to withstand temperatures up to 230°C (446°F) without melting or releasing hazardous emissions. Use inks that are not affected by the resin in toner. Inks that are oxidation‑set or oil‑based generally meet these requirements; latex inks might not. When in doubt, contact the paper supplier.
