  RGB Analysis for Forensic Discrimination of Blue Fountain Pen Inks
  Author(s): Ozlem Simsek* and S. Selim Seker
  
  This article intends to present a novel and rapid technique for distinguishing inks on disputed papers. The data was acquired by developing specialised image analysis software to assess thin-layer chromatograms (TLC-IA). This study marks Turkey's inaugural application of TLC-IA to analyse fountain pen inks, employing RGB profiles for ink differentiation. This work represents the inaugural investigation into fountain pen inks, employing TLC-IA with RGB analysis for ink differentiation. The ink spot was removed from the document with methanol and isolated by thin-layer chromatography utilising a plastic sheet coated with silica gel 60, devoid of fluorescent indicator, employing a mobile phase composed of ethyl acetate, ethanol, and water in a ratio of 70:35:30 (v/v/v). A novel software was developed to differentiate fountain pen inks based on the intensity profiles of red, green, an.. Read More»
