Case Of The Disappearing Ink

Case Of The Disappearing Ink
The 3M Company was developing a new ink hardening system. UV lamps were bleaching out the blue color so that this new ink looked like a clear coating. Why didn't this happen in the lab?
(Time 0:50)




Details

The 3M Company, a long-time leader in new technology, was developing a new ink hardening system. Normally, inks dry by solvent evaporation or they are hardened with heat.

The new approach would use ultraviolet radiation, or UV. UV has the proper photonic energy to cause chemical reactions, and the idea was to use this source of power to polymerize, or harden inks. Instead of taking minutes to harden, the inks could be finished in just seconds.
