...about printing both sides...seriously??? If you can't figure this out by your lonesome, then you should not be thinking about counterfeiting. You are one of those dumbass high school kids the SS hates going after. I will accept questions about the watermark, the type of paper, the color-shifting ink, intaglio, and other security features, but inkjet printing? My hush puppy could figure that out, and she really is a stupid bitch.
