PRINCIPLES OF IDENTIFICATION
It is the result of a very complicated series of factors, encompassing a combination of visible mental and muscular habits acquired through long and painstaking effort.
Some define handwriting as “visible speech.”
Handwriting
Kinds of Writings
A. Cursive - connected writing in which one letter is joined to the next.
B. Script - separated or printed writing.
C. BLOCK - all CAPITAL LETTERS.
Two Groups of Muscles Involved in Handwriting:
Causes of Variation:
Refers to the standard of handwriting instruction taught in a particular school. Different copybooks depend on the school’s adopted standard copy
SCHOOL COPYBOOK FORM (school model)
The combination of the basic design of letters and the writing movement as taught in school make up the writing system. Writing through the use diverges from the system, but generally retains some influence of the basic training.
System of writing
This refers to the shape or design of individual letters.
Form
It is the angle or inclination of the axis of letters relative to the baseline.
Slope or slant
a writing characteristi, it varies under different conditions and may have little nes the ration over pronounce example or a smal sample of writing like a signature
Size
Individual characteristics in the relative proportions of letters or parts of letters, such as the relative height of one letter compared to another, can be found in different styles of writing. Proportion of letters is one of the hidden features of handwriting.
Proportion
The relationship between tall and short letters is referred to as the ratio in writing.
Ratio
This refers to the strokes that connect one letter to the next. In signatures, it is common for many writers to connect their initials without lifting the pen. In regular writing, many writers habitually drop these connections before certain letters, especially small letters within words.
Connecting stroke
When a letter, word, or name (signature) is completed in free, natural writing, the pen is usually lifted from the paper while in motion with a “flying finish” (also referred to as “vanishing”, “9tapering”, or
“flourishing” terminal strokes).
Additionally, with many writers, the pen motion slightly precedes the contact with the paper at the beginning, creating a “flying start”, so that the strokes at the beginning and end of words gradually diminish or taper to a “vanishing point”.
Terminal Strokes and Initial Strokes
is an interruption in a stroke caused by removing the pen from the paper.
Pen lift
A gap between strokes due to speed in writing or defective writing instruments.
Hiatus
Lateral spacing is considered a common characteristic when it conforms to the standard copy-book form.
Lateral spacing
It is the widening of ink strokes with increased pressure on the paper surface.
Shading
Refers to the visible record of the basic movement and manner of holding the writing instrument in the written stroke.
Line quality
The relation of the parts of a whole line of writing or individual letters in words or signatures to the baseline.
Alignment
It is the balanced quality of movements, the harmonious recurrence of stress or impulse.
Rhythm
The average force with which the pen makes contact with the paper or the usual force involved in writing.
Pen pressure
Means “deviation from uniform strokes due to lack of smoothness, perfec parent even without magnification
Tremor
Variation due to the lack of machine-like precision of the human hand, fluenced by external factors such as the writing instrument and position, and physical and mental conditions like fatigue, intoxication, illness, nervousness, and age.
Natural variation
