    Abstract

    The following study takes a six-month look at the use of “erasable ink” on various types of paper using different types of erasers. In the examination of questioned documents. it is important to be able to identify if or when erasures or alterations have been made on a certain document. In recent years it has become easier for individuals of average ability to alter a document through the use of erasable ink. It is important for the document examiner to be able to identify if and when these inks have been used. By being familiar with the permanence that these inks gradually attain on various types of paper, the possibility of an erasure or alteration going undetected will be reduced. A practical evaluation, and update of different erasable inks, their erasability, and their permanence will be discussed.
