RIGHT: standard punches used for marking and coding applications in any sector when the impression on a product has to appear on the same side as it was stamped on. In this case the markings (whether a number, a letter or a symbol) on the punch have to be engraved as a reverse (mirror) image (see an office stamp for instance);
LEFT: standard and special punches used for marking and coding applications primarily in the field of dies, whenever you want to create a die for an object showing positive images of words/codes, in the food, pharmaceutical and parapharmaceutical product packaging sector (BLISTERING machines), where the marking on the product punched has to be read from the opposite side of the high-relief impression. In this case the punch has the engraved markings (whether a number, a letter or a symbol) in NON reverse (non mirrored) form.
