Q

The Principles of Handwriting Identification

A
  • No two writers share the same combination ofhandwriting characteristics.
    *Each writer has a range of variation centeredwithin his or her basic writing habits.

Q

Neuroanatomical Basis of Handwriting

A

primary motor cortex:controls fine muscle movement (e.g. finger movement)

53
Indirect: Tracing Paper
Tracing/highly translucent paper placed over genuine signature
54
Tracing Devices
Ghost Writer* invisible writer + developer Spectroline Signature Verification System* luminescent transfer product No Clue Fabric Marker* guideline washed away with tap water Reflection Sketcher* screen projects desired image onto blank paper Pantograph* enlarges/reduces signature by following lines of original with stylus Art Reproducer* mirror reflects down on paper for tracing

WHAT IS GRAFFITI?
writings or drawings that have been scribbled, scratched, or painted illicitly on the wall or other surface,often within public view

64
BLOCKBUSTER OR ROLLER
A large piece usually in a block-shaped style covering a larger area. It is created with paint rollers and exterior paint.

WILDSTYLE
It has interlocking letters and connected points. It is hard to read because letters are often undecipherable and merge into one another
