    Abstract

    A systematic evaluation of the effect of humidity on ESDA images was made. The results showed that the quality of the ESDA images developed depends not upon the water content of the paper at the time the indentations are made, but rather on changes in the water content, which may occur during the period between the indentations being made and the paper being examined using the ESDA.

    In order to study the effect of the moisture content on the quality of the image produced by the ESDA it was necessary to devise a system for producing standard impressions. This process has now found application as a quality control procedure for ESDA examination.
