Q9 Consulting, Inc. announces purchase of a new VSC 80 Video Spectral Comparator manufactured by Foster and Freemen in the UK. The VSC is used for discovery of alterations in documents. The high quality lenses provide detailed images for examination.

Ink Differentiation

The VSC uses several frequencies of infrared light to examine a document. Different inks may appear to be the same color when viewed in visible light. When the writing is viewed under various frequencies of infrared light, the different inks become apparent. This technique is used to determine whether a writing has been altered. Examples are changing a 1 to a 7 or adding an additional digit in front of a number such as changing 784 into 6784.

Authentication of government documents

Most federal government documents contain security features that can bee seen under ultraviolet light and/or florescence. The VSC contains illumination for several frequencies of ultraviolet light.

Several frequencies of ultraviolet light display various security features that are invisible when looking at the document in visible white light. Examples are a flying eagle and stars on the United States passport card.

Document alterations

Ultraviolet light is also used to discover alterations on documents where chemicals were used to remove ink.

The VSC offers the ability to zoom into sections of the document.

If you have a case that involves potential alteration of a document, contact Mike Wakshull at Q9 Consulting, Inc. The contact information is phone: 951-252-4929, email: mikew@quality9.com.
