Questioned Document Examination
Definition of Terms







3rd Century A.D. - The earliest handwriting examination cases reported.

6th Century - the Roman Emperor Justinian dictated guidelines for the
use of handwriting comparisons in Roman courts.

1873 - the year in which the first commercially successful
typewriter was introduced.

Addition - inserting or modifying clause or sentence in a document
to alter its meaning.

      Substitution - replacing original entries or writing with
      another.

Albert Sherman Osborn - became the pre-eminent American pioneer in
the field when he authored "Questioned Documents," a seminal work in
scientific document analysis that remains in print and in use. He
founded the American Society of Questioned Document Examiners in 1942.

Alfred Dreyfus - A French army officer, accused of treason through
letters found attempting to sell French secrets to Germany.
Later found that Dreyfus did not write the letters.

Alignment - relation of successive characters or letter of a word,
signature or line of writing to an actual or imaginary base line.

Alphabet - is a standard set of letters (basic written symbols or
graphemes) which is used to write one or more languages based on the
general principle that the letters represent phonemes (basic
significant sounds) of the spoken language.

Alteration - any change made on a document before, during, or after
its original execution.

      Methods of Alteration 
      1. Mechanical
      2. Chemical

Arrangement - habitual placing and positioning of letters and words.

Casting - was one method used to produce counterfeit coins in Britain
and America during the colonial period. Basically it consisted of
melting metal and then pouring the molten liquid into a mold having
a reservoir in the shape of a coin.

Class Characteristics - common to a group of people. Learned from
school or from an individual's parent or tutor.
Class Characteristics are similarities between individuals who learned
the same type of writing systems.

      Individual Characteristics - highly personal or peculiar to a
      particular writer. Influenced by habit, mindset, personal
      preference. It identifies an individual from other writers.

      Types of Individual Characteristics
      1. Skill level - the way a writing looks.
      2. Slant - is the angle of writing.
      3. Form - is the way a writer makes a letter or movement of
         letters. Most basic individual characteristic and is very
         important to QDE.
      4. Movement - is the way a pen moves in order to make a mark or
         form a letter. This can help distinguish the difference in
         form. 2 letters can be the same, but made in a different way.
      5. Proportions - is the symmetry of an individual letter.
      6. Height - is comparing the height of one letter to another.
         Height, proportions are usually habits found in a
         specific writer.
      7. “I” Dot
      8. “t” Crossing
      9. Loops - are similar to proportions.
      10.Pressure - is the difference in ink or pencil in width or
         shade. Helps show direction of movement.
      11.Baseline Alignment - The value of this show the questioned
         writing in correlation to the baseline. Helps QDE examiners
         determine whether the writing was altered or is consistent
         with the rest of the writing or other examples.
      12.Pen Lifts - Pen lifts are when the pen or pencil is lifted
         from the paper and reapplied to finish a word or sentence.
      13.Speed - The speed of a writer is a key indicator for QDE in
         the examination process. Fast and slow speeds are difficult
         to duplicate leaving behind inconsistencies in the writing.
      14.Embellishments - decorate writing. Usually found in the
         beginning of word, but can be seen other places.
      15.Entry/Exit Strokes -  is the way a writer begins certain
         letter or words and can be very specific to an individual.
         Also includes the idea of connecting stokes.
      16.Retracing - is considered fixing a portion of writing that
         is not readable or pleasing to the writer. In some cases,
         this can indicate forgery but is very common in normal
         handwriting to retrace letters or words.
      17.Spelling - is an individual characteristic because of
         education or habits and can be an easy fix to eliminate or
         pin point suspects.
      18.Spacing - is the area between letters or words and is usually
         specific to the writer.
      19.Format - is the habit in which a writer uses to depict simple
         things like; Dates, numbers, abbreviations.
         Example: The way people write checks
      20.Case - is a characteristic of a writer who might use upper
         case letters where a lower case should be present.

Coin Clipping - shaving off a small portion of a precious metal coin
for profit.

Coin Mutilation - cutting a portion of a coin.

Collected Standard - (Procured Standard)obtained from files executed
in the course of everyday routine.

      the purpose of comparative examination.

Color Shifting Ink - ink that changes color when viewed in different
angles.

Connections - links which connect a letter with the one following it.

Counterfeiting - imitate fraudulently for gain. To make a copy of,
usually with the intent to defraud; forge: counterfeits money.

Cuneiform - denoting or relating to the wedge-shaped characters used
in the ancient writing systems of Mesopotamia, Persia, and Ugarit,
surviving mainly on clay tablets.

document in question. Known authentic writing samples.

      Two Types of Exemplars
      1. Requested Writings - (Dictated) are writing samples taken
         from someone for the purpose of comparison with a questioned
         document.
      2. Non-Requested Writings - (Undictated)(Collected) these are
         examples of the subject's writings that are taken in the
         normal course of business or personal transactions.

Forensic Document Examination - the practice of the application of
document examination to the purposes of the law.

Graphology - is the study of handwriting to identify the writer's
personality traits.

Graphologist - Profiles character or personality by drawing conclusions

         of common characteristics between the known and questioned
         writing samples.
      3. There are no hard and fast rules for a sufficient number of
         personal characteristics; it is a judgment call made by the
         expert examiner in the context of each case.

Henry Mill - was an English inventor who patented the first typewriter
in 1714.

Hieroglyph - (Greek for "sacred writing") is a character of the ancient
Egyptian writing system. Logographic scripts that are pictographic in
form in a way reminiscent of ancient Egyptian are also sometimes
called "hieroglyphs".

Hologram - a three-dimensional image formed by the interference of
light beams from a laser or other coherent light source.

Microprinting - is one of many anti-counterfeiting techniques used
most often on currency and bank checks, as well as various other
items of value. Microprinting involves printing very small text,
usually too small to read with the naked eye, onto the note or item.

Obliteration - obscuring a document by a series of x-types, haphazard,
lines, blots, and smears.

Offset printing - or web offset printing is a commonly used printing
technique in which the inked image is transferred (or "offset") from

      Letterpress printing - is a technique of relief printing using a
      printing press. A worker composes and locks movable type into the
      bed of a press, inks it, and presses paper against it to transfer
      the ink from the type which creates an impression on the paper.

         and sealed with initial and date.
      3. Maintain chain of custody.
     
Questioned Document Examination - The scientific methods of
identification and examination of questionable documents, handwriting
examination, detection of forgery, falsification and counterfeiting of
documents which stress the procedures of restoring and deciphering
erasures and obliteration's; examination of documents by means of
visible light, ultra-violet light and ultra-red radiation and colored
powders; recognition and selection of standards; and examination of
questionable typewriting, computerized documents and other forms of
modern printing.

Retracing - any writing stroke which goes back over another writing
stroke.

Rhythm - the balanced quality of movement, producing a natural result
not constrained nor artificial.

Rubric and Embellishment - the additional and unnecessary stroke
incorporated in writing for decorative or ornamental purposes.

Samuel Willard Soulé - (January 25,1830-July 12,1875) along with
Christopher Sholes and Carlos Glidden invented the first practical
typewriter at a machine shop located in Milwaukee, Wisconsin,
in 1869.

Security fibers - are embedded in the paper during manufacture and
are non-reproducible.

Security Thread - is a security feature of many banknotes to protect
against counterfeiting, consisting of a thin ribbon that is threaded
through the note's paper.

Shading and Pen Position - the increase in width of stroke brought by
variations in writing pressure.

Sholes and Glidden Type-Writer - the first commercially successful
typewriter.

Signature - a person's name written in a distinctive way as a form of
identification in authorizing a cheque or document or concluding
a letter. From the latin word "signare" which means "to sign".

      Kinds of Signature
      1. Formal Signature - signature used on official documents such
         as will or deed of sale.
      2. Informal Signature - signature used in routine correspondence
         such as personal letters and other documents where you want
         the reader to recognize the signature but the exact spelling
         of the name isn’t important.
      3. Stylistic Signature - signature used in signing checks, credit
         card receipts, etc. This is also like the famous “physician’s
         signature” on a prescription. It is often highly stylistic
         and looks like a scribble with little that would be
         recognizable as a signature.

Signature Forgery - refers to the act of falsely replicating the
signature of another person.

      Popular Methods of Forging Signature
      1. Freehand Method -  whereby the forger, after careful practice,
         replicates the signature by freehand. Although a difficult
         method to perfect, this often produces the most convincing results.
      2. Trace-Over Method - the sheet of paper containing the genuine
         signature is placed on top of the paper where the forgery is
         required. The signature is traced over, appearing as a faint
         indentation on the sheet of paper underneath. This indentation
         can then be used as a guide for a signature.

            Methods of Signature Tracing
            1. Carbon Outline Method - carbon paper inserted between
               original and false document.
            2. Indentation Process - original document is placed over
               false one under it, to be traced later using a pen or
               pencil.
            3. Transmitted Light Process - a light source is placed
               under a light, the original document is placed under the
               false one. The light source will illuminate both
               documents so that the writings on the original document
               will be seen and traceable on the false one.

      Characteristics That May Suggest Presence of Forgery
      1. Shaky handwriting
      2. Pen lifts            
      3. Signs of retouching
      4. Letter proportions
      5. Very close similarity between two or more signatures

      Kinds of Forgery of Signatures
      1. Simple Forgery - (spurious forgery) signing of a document in
         his own or in a modified handwriting. Easy to detect once
         standards of genuine signatures are obtained.
      2. Simulated Forgery - (freehand forgery) the copying or imitation
         of a signature.

      Indicators of Forgery 
      1. Blunt starts and stops
      2. Pen lifts and hesitations
      3. Tremor
      4. Speed and Pressure
      5. Patching
         
Slant - slope of writing in relation to the base line.

Spacing -  is a blank area devoid of content, serving to separate words,
letters, numbers, and punctuation.

Striking - (stamping) making an impression of a coin on a metal blank
by pressure using steel dies.

Superimposition - placing or laying of one document over another
in a way that it appears as a single image. The placement of an
image or video on top of an already-existing image or video, usually
to add to the overall image effect, but also sometimes to
conceal something.

Terminal - The end of a writing stroke.

      Initial Stroke - the beginning of a writing stroke.

Tremor - deviation from uniform stroke brought about by lack of
smoothness.

      Kinds of Tremors 
      1. Genuine Tremors - caused by age, illiteracy, weakness.
      2. Tremor of Fraud

Typebar - one of the bars on a typewriter that bears type for printing.

Typewriter - is a mechanical or electro-mechanical machine for writing
in characters similar to those produced by printer's movable type
by means of keyboard-operated types striking a ribbon to transfer
ink or carbon impressions onto the paper.

      Carriage Return -  referred to a mechanism or lever on a typewriter.
      It was used after typing a line of text and caused the assembly
      holding the paper (the carriage) to return to the right so that
      the machine was ready to type again on the left-hand side of
      the paper (assuming a left-to-right language).

      Typeface - the printing surface of the type block. The most
      popular type are pica and elite.

      Pica - 10 characters per inch

      Elite - 12 characters per inch

      Types of Typewriters
      1. Keyboard typewriter - is the simplest kind of typewriter,
         functioning from the QWERTY formation of letters and having
         a type (a metallic cast with letters molded into it) that's
         attached by a bar or rod.
      2. Single-element typewriter - enable the user to print data in
         different languages or fonts. Instead of using a bar mold for
         the type (called a type bar), single-element typewriters use
         type wheels, type sleeves or type shuttles for molds. The
         most popular single-element was the Hammond type-shuttle
         typewriter produced in 1884.
      3. Type-bar typewriters, as the name suggests, use type bars,
         or molds of iron shaped like bars, for their types. Type bars
         are the most common kind of typewriter and the original
         invented by Sholes, Glidden and Soule was a type-bar
         typewriter.
      4. Index typewriters - were far less costly in the pre-modern
         era, but also less useful. An index typewriter required that
         users first input what key they would like, and then perform
         another action (usually pressing a lever) to print the letter
         to a page. Usually these didn't use type bars, but instead
         type wheels, type shuttles, type plates and even more novel
         types. Examples of the index typewriter are the American
         Visible, first manufactured in 1901, and the French Virotyp
         of 1914.
      5. Teletype Typewriters - (Teleprinters) came on the scene in
         the mid-1950s and peaked in popularity in the 1960s. They
         were used mostly for communicating information from point
         to point, much as modern fax machines are used. Most non-IBM
         computers had teletype terminals. Teletypes were completely
         mechanical and thus required regular lubrication; they didn't
         have type bars in the strictest sense and instead used
         plastic gears to print messages.
      6. Electric Typewriters - The most modern typewriter, still
         used today, is the electric typewriter, most notably IBM
         models such as the Selectric. The electric typewriter
         minimized the force necessary to print out a message by
         using a motor and type ball to print letters on paper.

Vignette - a small illustration or portrait photograph which fades
into its background without a definite border.

Watermark - a faint design made in some paper during manufacture that
is visible when held against the light and typically identifies
the maker.

Writing - is a medium of communication that represents language
through the inscription of signs and symbols.

      Cursive Writing - also known as script, joined-up writing,
      joint writing, running writing, or handwriting is any style of
      penmanship in which the symbols of the language are written in
      a conjoined and/or flowing manner, generally for the purpose of
      making writing faster.

      Writing Speed - Classified Into 4 Divisions
      1. Slow and Drawn
      2. Deliberate
      3. Average
      4. Rapid
