I invented a method for screenprinting scratch-off ink just like you'd find on a scratch and win ticket. The formula is pretty simple, just one part dish detergent to five parts block printing ink. It can be screened using standard mesh screens and though it occasionally bubbles will set into an even matte surface that can be scratched with a coin.
