1. Product introduction:
The vacuum coating fingerprint display system is our latest high-end product for fingerprint display, which can increase the display rate of fingerprints by 15-70%.
2. Application occasions:
v Applicable objects are mainly the appearance of potential fingerprints on the surface of non-permeable samples and some semi-permeable samples.
v For plastic products, metal products, electroplated surfaces, glass, wood products, leather, plastic paper, enamelware, ceramics, light-colored textiles, rubber, etc., the sweaty handprints on the surface of the inspection materials have a good display effect; secondly , It also has a certain effect on the fingerprints on the surface of the test materials such as weathered painted wood, natural wood, paper products and so on. At the same time, it is also suitable for reappearance of fingerprints on the inspection materials with poor effect of 502 fingerprints.
