Description
Mario Alejandro Alvarez Cordeiro and Catalina Gondikas examined pens filled with heat-sensitive ink, in a 2024 study. Such inks fade with heat or rubbing and then return, a trait that raises questions for document checks. The pair bought fifteen pens on sale in Córdoba, Argentina, and studied their strokes in detail.
Plain strokes all showed known marks of these inks, such as ink pooled at the end of a stroke. Slanted light revealed erased strokes by their contrast with the paper. Tests with ultraviolet and other light bands also set the inks apart from normal ones. Fine traits, like raised ridges where ink pooled, may help tell one pen's work from another's.
