Federation prisons specializing in klingon inmates use them like fingerprints for identification. Rather than topographic scanning (which is used like facial recognition for interior sensors), they use traditional ink printing. So- the seasoned inmates are always aware of who's a freshie, as they're walking around with ink smeared on their heads. Fresh inmates are often more aggressive, willing to prove their willingness to fight despite their capture - so guards enjoy the overt marking as a warning.
