    Abstract

    Prior to about 1950, the inks encountered on questioned documents were usually fluid inks of the washable dyestuff or iron gallotannate varieties. Analysis of these inks included observation under various wavelengths of light ranging from ultraviolet (UV) to infrared (IR), photography with selected filters, and chemical spot tests to detect metals such as iron, vanadium, and chromium. Since about 1953, the ballpen has taken over the position formerly occupied by the fluid ink pen.
