We use exclusively high-quality offset paper in 60 and 80lb for letterhead printing, which is then cut to 8.5x11" format. This paper is suitable for printing, copying, hand writing and stamping. You can't go wrong with 80lb paper, as it is the standard letterhead grammage and can be used to print any type of correspondence. This paper is a particularly good choice for printing advertising letters which are to be sent along with business cards, brochures, leaflets or calenders to keep the overall weight of the mailing at a minimum.
For letterheads intended for duplex printing, 80lb paper is too light, as the printed image on the reverse side can show through to the front. Letterheads on heavier paper are more exclusive, have a good feel to them, don't wrinkle as easily, are suitable for duplex printing, emphasise the effect of accompanying leaflets and put your company into a positive light: serious, dependable, successful.
