Product piracy has long been a staggering problem for the textile industry. DITF & IPA have developed an elegant solution: a fully transparent ink which is invisible to the human eye. The security ink is based on IR-active particles which are fixed on the substrate by textile binders. The patented high-tech transparency security ink can be applied to textile – without altering its look or feel – to ensure authenticity. Join Dr. Reinhold Schneider as he discusses the basics of invisible inks, ink formulation & optimization and a visualization of invisible inks using IR-light and IR-camera.
