当前捺印皮纹的主要的、常用的方法即油墨捺印。这种捺印方法,具有严重污染被捺印人皮肤的缺点,且施墨量、捺印力度与方向难以掌握。目前,对于活体皮纹,主要是引进了国外的药膜面卡片捺印技术;对于尸体皮纹,主要是运用载体转印粉末显现的方法。笔者另辟途径,设想通过胶带(或胶卡片)捺印皮纹,再经染色剂将纹线染色增弧反差,来实现比前法更简便易行的无污染捺印。本法所需的材料:·透明胶带(WING TAI TAPE/ADHESIVE CO·LID)·酸性品红(上海试剂三厂)·水(蒸馏水或自来水)操作方法如下:1.称取酸性品红1克置于烧杯中,量取水20毫升倒入烧杯,摇至完全溶解。2.取水至方盘中3/4深度。3.拉剪胶带(快速拉扯,防止产生小气泡和拉胶纹)若干段,然后分别让人体手、
At present, the main pattern of printing lines is printing inks. This stamping method has the disadvantage of serious contamination of the skin being smudged, and it is difficult to grasp the amount of ink applied, the printing speed and the direction of printing. At present, for the living dermatoglyphics, the main is the introduction of foreign drug film surface stamping technology; for the body dermatoglyphics, mainly the use of carrier transfer powder method. The author another way, envisaged by tape (or plastic card) to suppress the printed striae, and then stained by staining agent increased by the arc contrast, to be more simple than the previous method of pollution-free stamping. Materials needed for this method: · WING TAI TAPE / ADHESIVE CO · LID · Acid Magenta (Shanghai Reagent No. 3) · Water (distilled water or tap water) The procedure is as follows: 1. Weigh 1 g Placed in a beaker, the amount of water 20 ml into the beaker, shake until completely dissolved. 2. Take water to a depth of 3/4 in the square plate. 3. Shear tape (pull fast to prevent the formation of small bubbles and pull rubber lines) a number of paragraphs, and then let the human hand,
