Taking finger prints
Step 1:
We can use a magnifying glass (3) to find fingerprints
on comparatively smooth surfaces. Once a fingerprint
is found, spray fingerprint developing powder (5) onto
it, but take particular care not to damage the fingerprint
(as shown in Figure 1).
Step 2:
Figure 3
Reveal the fingerprint
Use the blower pump (1) to blow away the developing
powder sprayed onto the fingerprint gently (as shown in
Figure 2). This shows the shape of the fingerprint
Step 3:

Collect the fingerprint from the „crime scene"
Choose the most complete fingerprints and collect
them using the transparent stickers (4). Procedure:
Stick the adhesive side of the transparent sticker onto
the area with the fingerprint, press the sticker down
hard and then take it off. Stick the sticker onto the block
Figure 1
on the fingerprint „crime scene" card (6) (as shown in
Figure 3) and then write the place and time on the back
of the sample card.
Step 4:
Making fingerprint record cards
You can make fingerprint record cards for yourself and
your family members to keep your fingerprint patterns.
You can also compare and categorize them by the
following 8 basic patterns:
(1) Plain arc
(3) Ulnar loop
(5) Plain curl
(7) Double loop curl
(8) Incomplete whorl
(2) Tented arc
(4) Radial loop
(6) Central curl
Step 5:
You can use the ink pad (2) and fingerprint record cards
(7) supplied with the set for making fingerprint cards.
Record the name, age, time, left-hand or right-hand,
special fingerprint characteristics and other data on
each card.
How to record the whole fingerprint
(as shown in Figures 4 and 5)
Wash your hand clean and dry it. Start from the index
finger of the right hand. Open the transparent cover of
the ink pad. Press each finger onto the sponge of the
ink pad and roll it from side to side. Then, press the ink-
stained finger gently onto the fingerprint record card.
Do this for the index finger, middle finger, ring finger
and little finger in turn. As you press down, place the
end joint of your finger horizontally and then roll it from
side to side before lifting your finger off the card.
