Hi my name is alex and im in charge of making passes for my school. Its been hard for us to raise money because of all the bootleging. The person in charge before me had the best way of making it hard to copy unfortunately he passed away and kind of took the secret with him so to speak. He use to make the passes with a metallic like aluminum foil ink with lines i will include pictures. If someone could tell me what kind of ink and printer i need and how to print it i would really appreciate it.
