Color laser "secret" yellow dots
Was reading this article about how color laser printers print some secret yellow dot code and decided to see for myself if it is true.
Took this shot against my LCD monitor with 2x68mm extension tubes and 40mm lens. Guess it isn't a load of bullshit. Don't really see how it can help catch criminals though seeing as how laser printers can be bought 2nd hand.
I wonder what they will do next when too many people find out, secretly insert radioactive compounds into toner cartridges to print dots that show up only under special lighting?
