Bleeding is “the suffusion of color into adjacent materials; most often caused by water or other solvents” (Demeroukas 2010). This can often be seen on various substrates with soluble media such as ink or paint then exposed to water, solvents or high humidity levels.
Synonyms in English
Running, Blurring, Muddying
Paper objects with soluble materials such as ink are particularly at risk for bleeding. Bleeding can occur when washing the object in water or other solvents or if the object obtains water damage. Bleeding media may transfer media to other portions of the substrate or onto surrounding materials. (CCAHA 2000). Paint can also bleed from one area of a piece into another. (WCCFA).
