SignaScan, Inc., a California Corporation, is a state of the art Laboratory which has been involved in forensic research and questioned document examination, since 1987. Over one million dollars has been invested in equipment, research and Patents.
Signascan's focus is to provide objective, accurate and reliable scientific analysis of questioned document problems, with the intent to assist our Clients in the search for the truth.

The use of our "Computer Aided Document Analysis System" allows for exact and precise analysis. In analyzing questioned signatures or writings, for example, the system affords the exemplar writings to be equalized and superimposed on top of the questioned signature/s and writing/s. The writings are studied and compared at varying magnifications. This method of analysis is very precise and measurements are accurate to within 1/10,000th of an inch. Dual Monitor viewing of images, and variable magnifications, up to 500X, are also used.

There are many other document problems, for which our system affords precise and accurate analysis, such as: the study and matching of ink striations; non destructive pen and ink identification; white outs and obliterations; indented writings; alterations and other document problems.

Scientific methodology coupled with exact and precise measurement and comparison, provide reliable findings.
