Hinge Lifter
Definition
A pre-assembled lifting unit in which a clear acetate film hinged to a backing card is folded over a developed print, pressed, and re-folded to mount the lift, eliminating tape-handling bubble artefacts.
- Components
- Clear acetate film hinged to a backing card
- Method
- Fold over the print, press, then re-fold to mount
- Advantage
- Avoids tape-handling bubble artefacts
- Use
- Lifting powder-developed latent prints
Common questions
Why do hinge lifters produce fewer bubbles than tape lifts?+
Because the acetate film is pre-mounted on a hinge and pressed down in one controlled motion, the examiner avoids the manual smoothing and repositioning that loose tape often needs, which is exactly where trapped air bubbles tend to form and distort ridge detail.
When would an examiner choose a hinge lifter over standard fingerprint tape?+
Hinge lifters are favoured for larger or more delicate developed prints, or in training and high-volume processing settings, where the pre-assembled fold-press-refold action gives a more consistent result than hand-applying and smoothing a strip of tape onto the surface.
