How To: Do the Presto Printo card trick

To do the Presto Printo Card Trick, you need to begin with a deck of standard cards and a deck of plain white cards, which have been cut to the same size as standard cards. You will need to print the effects that you want to achieve on the cards in advance. You will need extra blank white cards to conceal. Lay the cards down on a surface to show that they are all blank, but you will be, instead, pushing a blank white card to imitate the opposite white side. Then, you will need to demonstrate the printing effect, by revealing the preprinted image. You will, of course, have to remember the order of the effects to pull it off.
