Watermark

Translucent logo in paper created during manufacturing by slight embossing from a dandy roll while paper is still approximately 90 percent water.<br><br>In the making of paper, a translucent design impressed on it when still moist by a metal pattern, and visible when the paper is held before light (back-lit). In digital imaging, bits altered within an image to create a pattern which indicates proof of ownership; so that unauthorized use of a watermarked image can then be traced.
