Watermark
A picture, text or character motif, which is incorporated into the paper during manufacture by displacement of the paper fibres, leading to a varying thickness of the paper. The watermark can be observed using transmitted light. Where the paper is thinner, we can see more light and a clearer image. Where the paper is thicker we will see a darker image. The watermark should not appear under UV light.
