    Abstract

    The use of correction fluid, or white-out, is a common method of obliterating, altering, or covering up unwanted writing or typing. Removal of the correction fluid deposit using a solvent is a destructive method of examination. Photography with transmitted light is a nondestructive method which is not always successful. A third method that is both effective and nondestructive is the use of a product that renders the paper translucent. This liquid is applied to the paper under the opaque correction fluid deposit from the back. As the paper becomes translucent, the writing on the paper but under the correction fluid deposit is revealed. It is photographed, and the negative is printed in reverse so the writing will read right. The visualizing fluid is both volatile and inert, and in most cases will affect neither the paper nor ink.
