Long Lasting Phosphorescent Inks

International Ink Company offers Long Lasting Phosphorescent Inks for Flexographic, Rotogravure and Silkscreen printing methods.  These inks are totally free of hazardous conventional radioactive substances.  Based on the new chemistry as a product of research and development, this ink has a very long lasting after-glow.  While old technology allows for 10 to 15 minutes after-glow, Long Lasting Phosphorescent Inks can glow between 2 to 8 hours, depending upon the ink deposit.  Improved afterglow can be achieved by applying a white basecoat under the phosphorescent layer.
