HOW FORGERS REPRODUCE SIGNATURES
In detailing matters which experience suggests as importantly
connected with the examination of disputed signatures, there are none
more essential to a proper consideration of the subject than an
understanding of those characteristics often appearing in forged
signatures, and by which they are distinguished as such. When the
features occurring as a concomitant of most forgeries are understood,
their appeara
ce may suggest a short and easy route to reach a
conclusion: yet the careful and conscientious examiner will, even with
these indications present in a disputed signature, institute a very
careful and detailed study of the latter by comparison with the
standard writings; and with as much effort as if the indications of
forgery were not present. To make these features positive evidence,
each other developed detail must also tend to the same deduction, and
each detail must be compatible with every other feature, and all point
to the same conclusion.
As forgers differ in their capability as to accuracy in simulation,
all grades of its proficiency come up in the experience of those who,
as experts, are called upon to make such matters a study. At one
extreme will be found to occur signatures written with but little
effort to imitate the genuine signature they purport to represent;
with all the intermediate grades of imitation extending to the other
extreme, wherein a skilful forger will, by practice, so simulate the
signature of a person and with such close resemblance that the very
individual whose name is imitated cannot, independently of attending
circumstances, tell the forgery from the signature which he knows he
has written.
Among the most common forgeries of signatures are those which have
been traced from genuine ones, and these are produced in various ways;
the most common method being to place the genuine signature over a
plate of glass horizontally arranged, with a strong light behind it,
or against the window frame, and then to place over the signature so
positioned the paper on which the forgery is to be made. When this has
been done the papers are held in contact firmly, the pen is dipped-in
ink and moved over the paper, guided by the lines of the genuine
signature beneath, which show through the superimposed paper, and by
means of which the form of the signature is transferred to the paper,
which is exteriorly placed.
While the process of tracing produces very nearly the proper form of
the matter thus copied, and if well done by the forger the copy will
in general appearance and to a certain extent resemble in outline the
signature thus traced, there are usually apparent in all reproduced
signatures thus made, peculiarities and ear marks indicating the
manner in which they were produced and by which they can be identified
as such.
One of the most prominent features of reproduced signatures is the
general sameness of the writing as appearing in the uniform width of
the lines, and the omission of the usual shading emphasis. The cause
of this appearance is the absence of habitual pen pressure, and the
necessitated slow movement of the pen held closely in contact with the
paper and by which a uniform and steady flow of ink is deposited
thereon; thus making what should be the heavier and lighter lines of
one width and density as to shading. This method of tracing and
reproducing signatures is that usually resorted to by novices but is
seldom employed by expert forgers.
Another condition appearing in all traced signatures is the absence of
all evidence of pen pressure when examined as a transparency; this
deficiency occurring as consequent upon the manner of moving the pen
over the paper. While signatures thus made may resemble the one from
which they are copied, the only likeness they have is that of
pictorial resemblance and it will be found to be destitute of all the
appearances and indications of habitual writing in other respects.
Another method of tracing signatures is frequently resorted to by
persons adept in the art, and this consists in making a lead-pencil
copy of the genuine signature holding the paper on which the forgery
is to be produced; tracing the outline of the signature by means of a
pencil, and then with ink to write over the pencil copy. But as the
method necessitates the use of an india rubber to remove the surplus
black lead where not covered by the ink, evidences of the use of the
rubber will be found to occur, and traces of the black lead can be
found by the microscope. While the appearances and conditions are
common to traced signatures, there are in addition to their presence
generally found evidences of pauses made in the writing, the effect of
which will appear not as shading of the lines, but as irregularities
or excrescences produced thereon by resting the hand in its movement,
and by which at intervals more ink flowed from the pen than would
occur when the latter was being moved habitually over the paper. Where
the signatures of the same person exactly coincide when one is laid
over the other in parallel arrangement with a strong light behind
them, this condition of their appearance is very positive evidence
that one of them was traced from the other and is a forgery, as it is
a circumstance which cannot possibly occur in the writing of two
signatures produced habitually.
In considering reproduced signatures and forged writing and in
detailing some of the most common features which are found to occur in
it, it must not be understood that all the phenomena attending the
production of forged signatures can be given. Inasmuch as each person
has a peculiar muscular co-ordination that is manifested in the
production of habitually written signatures, so each forger from the
same cause has an individual habit that must be used when simulating;
hence there will be as many styles of writing manifested in production
of forgeries as there are forgers to produce them. No positive rule
can be laid down for the classification of their peculiarities
excepting the manner of accuracy with which the simulation appearing
in them is done. Each case of disputed writing must be examined by
itself, and while there are certain process steps to be followed which
experience suggests as facilitating the analysis, yet the examiner
must wholly depend upon what is seen in the disputed signature that
is, or is not, found in the admittedly genuine writing of the person
whose signature is questioned, and the comparison of the one with the
other.
Reproduced signatures often show a copying effort that is manifested in
the details of their production. These evidences generally appear, in
some instances, as pauses made in the lines connecting the letters of
the signature, where the pen rested while the eye of the forger was
directed from the writing being done to the copy, that the writer could
fix in the mind the form of a succeeding letter. These pauses appear in
different measure of prominence in different forgeries, and there is no
rule as to their measure or appearance. With some forgers the pen rests
with considerable emphasis and with others it is lifted from the paper
and returned to the paper while the eye of the writer goes back to the
copy. With others there will appear but little hesitancy. Some forgers,
well skilled in the art, will, by practicing the simulation until they
have the form of the genuine signature well fixed in the mind, become
enabled to produce a forged copy of a genuine signature that will show
no pauses--hence the absence of pauses is not proof of the genuine
character of a signature. Another common characteristic of forged and
reproduced signatures and particularly such of them as are not traced
and are produced by persons not skilled in the art is found in the
studied appearance which they have, as if written under restraint, and
without the apparent freedom consequent upon habitual writing. Another
characteristic of forged signatures that are not traced from a genuine
signature is that they are written with greater length in proportion
to the width and height of the letters, than occurs in the genuine
signature from which they are copied in imitation. This want of
proportion occurs generally from making the lines connecting the
letters of the signature longer than those of the copy.
At the same time, while these characteristics are common to forged
writing, to make them available in formulating an opinion from an
analysis they must be substantiated by every other occurring in the
writing. It must be clearly kept in view that general impressions
derived from a cursory examination of a disputed or reproduced
signature should have no weight in the mind of the examiner before
proceeding with the analysis, as such an impression is apt to lead the
investigation into a particular line of research and it should be
understood that the work of the examiner must relate to the comparison
of the details in each of the writings as to their correspondence or
difference.
As before stated in this chapter, and a fact that should be remembered
in studying fraudulent signatures, that one of the commonest and
easiest means of reproducing a signature is to put the genuine
signature on a piece of glass, lay another piece of glass on top of it
and fasten the piece of paper that is to receive the forgery on top of
that. Then by holding the glass strips to a bright light, the original
signature casts a shadow through, which may be traced in pencil. From
this tracing the ink forgery is completed.
But when a forgery done in this way is put under a strong magnifying
lens it will not bear scrutiny. If the original has a strong down
stroke on the capital letters the movement will be free and will leave
the pen lines with smooth edges. The man who is tracing such letters
cannot trust himself to the same free movement of the pen and the
result under the glass shows hesitancy and uncertainty. Also if other
lines in the signature be lighter than the forger naturally uses the
same hesitancy will be shown. When the lines have passed scrutiny, too,
there is another "line" test which will show that the impossibility of
one's writing two signatures alike has been accomplished.
From dotted points made above the genuine signature straight lines are
drawn radiating from it to certain portions of certain letters in the
signature that is forged. When the forged signature is replaced in the
glass and the other on top, as is done in the tracing, these radiating
lines will fall one upon the other with the exactness of the lines in
the signatures.
These radiating lines, too, may be used in the few cases where the
forger is an expert penman depending upon an offhand duplication of a
signature. This penman will have his inevitable natural slant to his
letters. This characteristic slant never is the same in two individuals.
In his free and easy forgery of a name written by another person this
"Jim, the penman" exposes his acquired slant which disputes the original.
This slant of individual writing shows especially in any attempt to
write a forged letter or document. When the pen scope of the original
has been lined out, proving the characteristic common lengths between
the lifting of the pen from the paper, the lines radiating from the
points to individual letters in words or groups of words in authentic
and bogus specimens, these radiations point at once to the fact that
the same person did not write the matter.
These are some of the things upon which the handwriting expert works
upon and brings to bear in proof of reproduced signatures and
handwriting in general. How the more or less inexpert person discovers
questionable showing in these duplications are many. His intuitions
may suggest his doubts. Material evidences may have come to bear upon
him. Likelihood of some one person's having self-interests in the
matter may induce him to make sure.
In the case of a banker or business man, having large interests and
required to affix his signature to many papers of moment, he ordinarily
makes it certain that through adapted whorls and freehand sweeps of the
pen, the signature will be least careless and inviting to the
adventurous forger. In much of his personal correspondence with
strangers, however, this adapted and unusual signature frequently
becomes a source of loss to himself and irritation to his correspondents.
In the case of hundreds of such individuals, the writing to a stranger
in expectation of a reply becomes an absurdity for the reason that
the person addressed is hopelessly barred from reading the name
attached to the letter. A plain signature is always the best.
