The stability of photocopied and laser-printed documents and images [electronic resource] : general guidelines / by David Grattan. Ottawa : Canadian Conservation Institute, c2000. 7 p. : ill. Technical bulletin ; no. 22 Issued also in French under title: Stabilité des documents et des images photocopiés ou imprimés au moyen d'une imprimante laser, lignes directrices. The catalogue number (NM95-55/22-2000E) and ISBN (0-662-28503-4) and ISSN (0706-4152) for the print edition have been copied in this electronic publication. Includes bibliographic references. This bulletin reviews the technology of photocopiers and laser printers, and discusses the stability and preservation of copies. The conclusion is that black-and-white copies (i.e. those using carbon-based toner) on alkaline paper form very stable records, but colour photocopies do not. A fullsheet test for assessing the adhesion of toner to paper is described, and the results of testing papers according to the American Society for Testing and Materials (ASTM) standard for permanency of copy paper are given. The bulletin also includes a list of preservation concerns that will be useful to archivists responsible for the care of photocopied documents, and a number of current technical references that discuss the topic in more depth.
