    Abstract

    A method for the forensic science characterization of black printing inks is presented. High performance liquid chromatographic techniques have been developed for the semiquantitative analysis of pigment components and manufacturing artifacts present in alkali blue pigment, which is commonly found in black letterpress and offset inks. These analyses have shown that differences can be demonstrated in the component makeup of alkali blue from different sources, and that these differences may be useful in showing relationships or a lack thereof between evidentiary ink samples.
