All paper stocks begin life without a coating. Uncoated paper is porous with an uneven, rough surface. As a result, uncoated paper is easier to write on as it absorbs ink readily and dries to the touch faster. However, the heavier ink absorption results in less rub resistance.

Uncoated stocks include bonds, offsets, card, and newsprint.
