Description A watermark is a recognizable image or pattern in paper that appears as various shades of lightness/darkness when viewed by transmitted light. It is caused by thickness or density variations in the paper. There are two main ways of producing watermarks in paper; the dandy roll process, and the more complex cylinder mold process.
