TreadPrint™ is the fastest and easiest way to obtain exemplars of tire tracks. This replacement TreadPrint™ applicator is filled with Identicator’s PerfectPrint ® ink and is used to apply the ink to the surface of a mounted tire. The tire is then rolled over pre-cut cardboard panels. The special ink won’t dry on the tire, but dries immediately once contacting the paper, leaving a dark, black impression that won’t fade. No further development or protection against smudging is required.
