| There are 2 types of watermarks: |
Shaded
The shaded mark is the result of a design recessed in the surface of the dandy roll. When the pulp flows into these watermark recesses, different gradations of tone are created. The result is a watermark that is shaded, or darker and more opaque than the surrounding sheet when held to light. |

Wire
The wire mark is the product of a raised design projecting from the surface of the dandy roll. This "wire" is pressed against the forming paper, displacing its fiber in a line art-looking fashion. It creates a watermark that appears translucent, or lighter than the surrounding sheet when held to light. |
