The Revolutionary system of the Modico Self Inking stamp places the ink pad behind the printing plate which is made of a microporous foam material that stays ink-permeable only at the unexposed areas. When you press the stamp, the ink is being dispensed through the ink-permeable areas of the text plate onto the paper. This is why there isn't any loss of quality, which is the result of the uneven transfer of ink from the ink plate onto the text plate that is a common problem with conventional wooden- or self inking stamps made of polymer or rubber.
