A lifting process for determining the writing sequence of two intersecting ball-point pen strokes

The authors describe a technique for determining the order in which two intersecting ball-point pen strokes were made by means of lifting part of the ink with KromeKote paper. The KromeKote paper is applied to the intersection with the glossy side against the writing. The back of the lifting paper is rubbed with a blunt pointed instrument using moderate pressure. Study of the lift under low magnification discloses a pattern of edge markings with those from the last written line dominating the intersection. Results show a high percentage of accuracy.
