But isnt it the oil on your fingers that actually makes the print? If they are covered, how would the oil get through the glove? I can see maybe those lunch lady gloves, they are basically baggies over their hands, but still, all you should need is a barrier between your fingers and the item you are touching. Maybe my thinking is flawed, but I would think that a latex glove should be just fine. unless, the oils from your hand can get through it.
