The letterhead is the best way of communicating yourself to the client and customer. The quality can vary from a plain 100gsm paper with one colour ink, to the very best textured paper, watermarked and heavy weight.
Most customers print on a quality 100gsm white paper but the alternatives are numerous. Unfortunately, due to the competitive state of the paper market, papers come and go on a daily basis. So, your paper of choice may have disappeared the next time you print!
Textured papers are very popular. Laid sees your paper textured with lots of lines.
whilst hammered creates a bubbly effect. The name of the effect varies according to the paper supplier.
