Problems solved by technology

Professional collection requires special equipment, special ink, special paper and professional operation. The operation is complicated and costly, and it is not easy to be widely used; ordinary printing pads or ink pads, printing ink cartridges have unclear fingerprint images and lines, and are not suitable for automatic fingerprinting. Identification technology input and identification; at the same time, both collection methods have the problems of not being easy to clean and not environmentally friendly

Abstract

The invention discloses a fingerprint stamp pad, which comprises a pad cover, a pad base, an ink storage cushion and stamp-pad ink, and additionally comprises an ink control cushion, wherein the ink control cushion is arranged on the ink storage cushion, the stamp-pad ink comprises the components in percentage by weight: 10-20 percent of paint, 5-15 percent of water solube resin, 40-60 percent of humectant, 1-5 percent of emulsifying agent, 5-10 percent of thickening agent and the balance of water. The fingerprint stamp pad of the invention has simple operation and low cost, and can reach the effect of generalization and use. The success rate of fingerprint acquisition is high, non-professional personnel can also acquire the fingerprint image with clear lines and good quality, and the invention meets the requirements of input and identification of the automation fingerprint identification technology. The stamp-pad ink does not contain harmful substance, meets the requirement of environmental protection, and when being stuck on clothes and the skin, the stamp-pad ink is easy to clean, and can not hurt the skin.

Description

technical field [0001] The invention relates to a stamp pad, in particular to a fingerprint stamp pad used by public security and banking systems to print living fingerprints for evidence collection, and belongs to the technical field of stamp pads. Background technique [0002] Because of its lifelong invariance, identifiability, and classifiability, fingerprints have been recognized as "the first physical evidence" and "the most reliable seal". The application of automatic fingerprint recognition technology has made fingerprints widely used in public security and banking systems as physical evidence and anti-counterfeiting. How to collect clear and complete fingerprints conveniently and quickly has become an urgent problem to be solved. Existing fingerprint collection is divided into professional equipment collection, common printing pads or ink pads, and common printing ink cartridges. Professional collection requires special equipment, special ink, special paper and pro...
