At FBI CJIS' website about recording legible fingerprints, the following explanation applies:An individual may, by the nature of their work or age, have very thin or worn ridges in the pattern area. Light pressure and very little ink are used to record these types of fingerprint impressions. A technique known as "milking the fingers" can be used to raise the fingerprints prior to fingerprinting. The technique involves applying pressure or rubbing the fingers in a downward motion from palm to fingertip. In a situation of dry, flaky fingers, simply add a small amount of hand lotion or ridge builder prior to fingerprinting. Thus, the key to recording fine ridge detail of children's fingerprints, or the fine ridge detail from the soft fingers of elderly persons (whose friction ridges may be worn, but in many instances are more accurately described as thinning due to senile atrophy of the skin) is often light pressure and very little ink. Caution should be used if you are considering trying to "milk" the fingers of a child, because their fingers are more fragile than adults and they may not be able to verbally communicate that you are hurting their fingers. There are also other simple ways to record a child's fingerprints, such as having them rub their hands over the dark photographs on news papers, then lifting the faint "printers ink" coating their fingers with Scotch tape and applying the tape to a white paper background. |

When fingerprinting a child is difficult due to soft skin, you can help define the ridges by what procedure?
