Tradicional (cellulose) and cotton paper thickness differenceBusiness cards, invitations, letterheads and postcards we use to print on two type of paper – pure cotton paper and traditional, premium quality, paper made of cellulose fiber. Both types of paper are very nice just they are produced differently. A traditional sheet of paper is formed with heated rollers. It uses an intense pressure to form a high-density paper, which is from about 250 gsm quite rigid stock. The surface of mould made cotton papers has a beautiful random surface texture, soft and good-tempered nature, and is a strong and stable enough sheet to ensure excellent printing. The same grammar cotton paper is much thicker than traditional paper, but due to its relatively low density, it is not so rigid if compare to regular papers. We have made a table, to show how the card stock thickness of these two different made papers varies depending on GSM. *Different colored rows contain different paper descriptions:
