Use these guidelines when selecting preprinted forms and letterhead:
- Use grain long for 60–90‑g/m2 (16–24‑lb) paper.
- Use only forms and letterhead printed using an offset lithographic or engraved printing process.
- Avoid paper with rough or heavily textured surfaces.
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 your paper supplier.
