Perfect Print ® Ink, 2 oz. (60 ml) Perfect Print ® ink is a special paste-type fingerprint ink for use with slabs and rollers and our Printmaster ® inkers. It differs from standard fingerprint ink in that it doesn’t require special solvents to clean. It simply rinses off of equipment and hands with water. Unlike standard ink, Perfect Print ® ink dries immediately on the card, but doesn’t dry on the slab, making application simple and reducing the number of rejected fingerprints. Perfect Print ® ink is permanent, non-toxic and won’t deteriorate rubber rollers.
