Quality assessment of alternative patent fingerprint method using alcohol gel and thermal paper

Fingerprints are unique structures made up of a combination of friction ridges. Due to the individual characteristics of fingerprints, it is used commonly used for identification. Traditionally, patent fingerprints are obtained using an ink pad. Unfortunately, the print takes time to dry on pape...
