This method is based on a quantitative analysis allowing for a more objective approach to identify the questioned crossing sequence correctly as opposed to a subjective visual examination. The color of questioned crossing strokes and their nearby two single colored points is measured by microspectrophotometry. Next their three parameters of CIELAB uniform color system are separately obtained (Lightness, Red-Green Axis, and Yellow-Blue Axis). By using the same or similar pens, the sample strokes can be duplicated. The color of their single colored points is most similar to their respective single color of the questioned crossing. By matching the colors of the questioned crossing and the two duplicating sampleþs crossings, the writing sequence of the questioned sample can be determined as the more similar duplicating sample.
