What are the ways of highlighting fingerprints in modern times

At present, the fingerprints are highlighted in the following ways:

•  By powder

•  By Iodine Gemming Gun

•  Through Nine Times

• Through the Silver Nutrient Solution

1- Use of powder



Powder is used on the surface as opposed to surface colour. Powder is used on the black surface and black powder on the white surface.

2- The use of iodine gaming

The iodine can be seen from the gumming gun, especially on paper, on ivory, on paper hidden on wood, or on other types of paper.



3- Using the Rain Rhine



It will only be used to display marks on printed papers. It is watery and weak.



4- Using Silver Nutrition Solution



If this solution does not appear on hidden papers using the mark number 3 or the band Rhine's use, then it will be marked with the use of silver nitrate.
