This section applies to the inspection of seals and seals in the field of forensic science.2 EquipmentLight-transmitting board, comparison microscope, graphics (image) processing software with coincidence comparison function, document inspection instrument, copier, scanner, camera, etc.3 Inspection3.1 Transparency coincidence comparison The printed text (original or copy) is superimposed on the light transmission observation to compare the coincidence. 3.2 Comparative microscope coincidence comparison Place the matched seals horizontally on the stage and perpendicular to the optical axis, using the same magnification and brightness. The articles are compared and compared. 3.3 Using graphics (image) processing software for coincidence comparison Use the image (image) processing software's coincidence function to compare and compare the printed text at the same magnification. 3.4 Using the coincidence function of the document detector Use the coincidence comparison function of the document inspection instrument to perform the coincidence comparison of the printed text under the same magnification.4 Make inspection recordsThe inspection result of coincidence comparison shall be recorded in the inspection record. If necessary, you can place the overlapping comparison pictures, and the details of the overlapping parts Label or text description of the form, relative position, etc.5 matters needing attention5.1 Should be combined with the material of the seal, the method of inking, the storage conditions, the use conditions, the use time, the folding of the printed text, the paper stains and other factors Analyze the similarities and differences of coincidence. 5.2 When using translucent coincidence comparison, in order to enhance the comparison effect, the printed text can also be copied to a transparent or translucent carrier at the same magnification Comparison. 5.3 When using graphics (image) processing software for registration and comparison, the deviation of the picture during the collection process (such as scanning deviation, camera shooting angle) ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GA/T 1690.2-2019_English be delivered?Answer: Upon your order, we will start to translate GA/T 1690.2-2019_English as soon as possible, and keep you informed of the progress.
