To make fake fingerprints you need the originals first. Potential fingerprints are nothing more than grease and sweat on objects that have been touched. So to find someone's fingerprints (in this case the fingerprints you want to reproduce), you have to rely on proven forensic research methods. Which is what we want to explain here.
Steps
Step 1. Find some good counterfeits
A good source of originals for our counterfeits are glasses, doorknobs and glossy sheets. The standard forensic method makes them visible: sprinkling them with colored powder, which sticks to the fatty substance.
Step 2. Find something similar to super glue
Another solution includes cyanoacrylate, the main ingredient in superglue. A small amount of this is poured into a bottle cap, which is tipped over and placed on the fingerprint.
Cyanoacrylates dissolve and react on contact with fat, turning into a white and solid substance
Step 3. Make a digital reproduction
Subsequent treatment includes scanning or photography (figure 5) and a bit of a graphic makeover.
The goal is to obtain an exact image of the fingerprint, to be used as a mold for later use, from which the reproduction is obtained. The easiest way is to print the image on a glossy sheet (usually used for projectors) with a laser printer. The toner forms a relief, which is later used as an embossing. Wood glue is great for making forgery
Step 4. Use a thin layer of glycerin to make the most of moisture and malleability
After a meticulous stirring, the reproduction is covered with a thin layer of the compound.
Step 5. After the glue has dried (Figure 10), remove the foil (Figure 11) and cut it into the shape of the finger
Step 6. Glue the forgery to your finger
Theater glue is used to attach the reproduction to your own finger. The new identity is ready!
