The EN6 is a Black Resin and Overcoat ribbon for imprinting black text, barcodes and images on cards with the Holocoat security feature on top. MA600KO provides a very thin overcoat which may help protect the imprinted image.  This overcoat is not a laminate, which is much thicker. Typically used for batch printing of the back of cards when customized information is not needed, or to print custom black text and/or barcodes on preprinted cards.
