    It’s not specific to USA… They do it everywhere - with color-printers. Don’t know if they do it with B/W printers.

    They claim it’s to track people who try to print money, but if it were, then they wouldn’t really do it on laser printers too…

    If you print a photo on a regular paper, and then shine an UV-light on it, you can see it. It’s mostly small yellow dots.
