Blotter Paper Artwork, Prints & Art- Blotter paper is made from different materials of varying thickness, softness, etc. depending on the application. It is often made of cotton and manufactured on special paper machines. Blotter paper artwork is printed onto blotter paper and then sometimes perforated into tiny squares or "tabs" which can be torn or cut apart. Most blotter art designs have grid lines as part of the design to either aid in perforation or to be left as a cutting grid.
