I am frequently asked whether faded text on documents can be enhanced. Unfortunately, there is very little that can be done to reverse the damage, however, a website has recently come to my attention which may be of use. retroReveal is a service offered by the University of Utah, where images uploaded onto its website can be processed in several ways in order to enhance text. Beware though, you will need a certain amount of technology savviness in order to use it.
An alternative method is to take a digital photograph of your text and manipulate the contrast in one of the many photography software packages available.
