Dear all I wonder whether you can help on a conservation matter. The Museum Document Association (MDA) has informed a museum colleague that all Museum artefact entry forms have to be on archive paper using permanent ink. The Museum colleague would like to know if anyone has carried out any tests on the longevity of ink used in computer laser printers. Answers would be greatly appreciated.
