True Watermarked Papers – Definition

A true watermarked sheet of paper has an image or logo that has been embossed into a roll of paper, using a Dandy Roll during the paper making process. Typically, these master rolls are then converted into 8.5” x11” sheets. The embossed area becomes visible and appears lighter when the sheet is held up to a light. Many fine cotton or rag papers have true watermarks. Strathmore, Hammermill and Cranes Crest all supply true watermarked paper incorporating their brand’s logo. Historically, True Watermarked Paper was used to convey a symbol of quality, however today true watermarked paper is often used to prevent document counterfeiting. Because a true watermark is very difficult replicate it is a very effective deterrent to copying.

Chemical Watermark – Definition

An option to watermarking paper during the paper manufacturing process is the process of chemical embossing a watermark. A chemical watermark is created using a chemical process that changes the structure of the paper. A dissolving agent is applied to an embossing die (your image), the die strikes the paper and the dissolving agent applied to the die dissolves a portion of the paper cellulose leaving just the translucent image. This creates a watermark that appears almost identical to a watermark created when a papermill manufactures the paper.
