Computerized Perforation Measurement Software
According to a write up on their website, "If you are like most collectors, using a traditional plastic perf gauge is difficult and error prone. Most of us can barely see the tiny lines on the pastic gauges, let alone trying to align them with the stamp. EzPerf solves that problem."
It goes on to say, "Finding that rare perf is much easier with EzPerf's batch option. Lets say you had 40 copies of a very common stamp, but there is a rare perf variety you are looking for. Measuring each one individually can be tedious and difficult at best. With EzPerf, simply scan the stamps & place them into a folder on your hard drive. Then run EzPerf in batch mode & it will measure each one and give you a report of the perforations of each stamp. A quick glance will let you instantly see if any perf varieties are in your batch."
Cost is $39.95.
