Application of Computed Radiography (CR) for Characterization of Historical Documents
Watermarks and paper structure are significant properties of historical documents that allow historians and restorers possibility of dating where and when a particular paper was produced. Because of the document content (text, graphics etc.), it is sometimes difficult or even impossible to determine the layout of the watermark and paper structure using only light transmission technique. In that case, radiography can be used as an alternative method. In this paper the possibilities of using computer radiography (CR) for watermark extraction and paper structure characterization as well as advantages and disadvantages over conventional film radiography are discussed. Optimization of CR radiographic parameters (selection of imaging plates and radiation sources) for low-voltage X- ray and electron transmission technique was conducted and the results were compared to light transmission technique findings.
