It's probably very faintly visible in ordinary light, but what makes fluorescent ink interesting is that it fluoresces, i.e. it reflects UV light in the visible spectrum, which makes it seem brighter than normal pigments. So the blacklight makes it much more visible.
- Wowfunhappy 7y agoAh! So in the words, the printer is placing a thinner (ie, too thin) layer of ink on the paper than a human with a highlighter would, right?
- StevenWaterman 7y agoYep, printer ink has much more pigment in it because a few ml of ink has to cover hundreds of pages
