Regarding "invisible inks" that are not normally visible on the finished sheet, but which glow brightly under 365, 280, or 254 nanometer UV irradiation.
For the printers that use these inks for anti-counterfeiting, brand protection, or other purposes, how do you control the printing process to assure a readable or scanable image?
How do you assure sufficient coverage? How do you prevent over-deposition, wasting expensive materials?
How do you check image placement on web presses such as flexo label presses?
This is, of course a loaded question. Please wait for the other shoe to drop.
Thanks,
Larry
