The paper stock behind a business card does more work than most people realise. A 300gsm card feels noticeably more solid than a standard 250gsm sheet, and that weight is often the first thing someone notices before they've read a word.
Matte lamination gives a soft, premium touch and hides fingerprints well, while gloss lamination makes colours pop and photography look sharper. Uncoated stock, on the other hand, is ideal if you want a card that can be written on.
For most businesses, 350gsm with matte lamination hits the balance of durability, feel and cost that works across almost every industry.
