Pantone colour Letterhead Printing. Some companies require their letterhead printing to incorporate specific Pantone® (PMS) Colours. This requirement is normally dictated by the Corporate Identity of the Company using one, two or three spot colours. If you have a colour specific brand then this range of letterhead printing is the right one for you. Our spot colour range is printed on 120gsm Vision or 120gsm recycled bond. If you provide your artwork with the correct pantone number references then we will do the rest!
