Accurately Grade and Measure Stamp Perforations The Stamp Analyser digitally measures the stamp perforations, the stamp frame and the balance among the four margins to determine the centering grade of the stamp. It also allows you to measure the distance between any two points on a scanned image. The Stamp Analyser provides this information based on accurate measurement; no more guesswork. All you need to do is to provide a good scan of the stamp and the Stamp Analyser does the rest. Optionally, you can add the stamp Soundness and Eye Appeal components to obtain the final grade. The Soundness and Eye Appeal components are based on the PSE Grading Guide. The Stamp Analyser user interface has been designed to be intuitive and simple. On the PC you simply drag and drop your stamp image into the Stamp Analyser. More screenshots​ and information at rakium.com.
