V458-D ink produces a red, light-emitting fluorescent code when illuminated by a UV light. These red fluorescent images can be read on high-speed production lines immediately after printing, even when printed on multi-color surfaces. Additionally, the ink produces a human-visible pink color making it easy to conduct immediate visual code quality checks during the production process, or downstream in the distribution supply chain.
The ink is specially formulated with a unique set of fluorescent and visible dyes combined to provide machine and human readable codes on a variety of differing color backgrounds. Various methods of illumination may be used to activate the dye and enable it to fluoresce. Primary applications include automotive and automated parts marking and codes included as part of track and trace applications.
