Natural Variation in Signature

One of the most popular writing acts used to identify a person is a handwritten signature. The signature has become increasingly unique as a style has been applied to its execution. Because there are no rules for drawing or producing signatures, they are free to do it according to their own preferences. A signature can be written in a variety of ways ornamentation. Even if the writer signs, no one ever signs exactly the same from one time to the next. They have some known or called natural variations, as well as several signatures at the same time variants. Natural writing requires a lot of variation. The degree and type of variation vary from person to person writers, as well as a significant alignment in the identification.  Variation is mostly due to the human body's lack of machine-like precision, but it is further exacerbated by extrinsic factors such as writing position, writing tool, and execution care. Physical and emotional factors such as stress or lassitude, intoxication, disease, anxiousness, drug usage and also the passage of a long period of time might cause variance. Variation does not result in handwriting identification.

NATURAL VARIATIONS 

A signature is subject to natural variations. As with printed signatures, no one can duplicate a signature perfectly. The output of a person's writing might have a wide range of differences. Some people, like writers, are very consistent while others are exceedingly varied. Signatures can be formed in a variety of locations. Certain signatures are more comfortable to make and hence exhibit distinct natural variances. In other cases where writing is difficult, the outcomes may be slightly different.

This shows that the samples may be written by different writers. Sometimes these differences called consistent differences are quite small. But their reproducibility within each sample and their consistency may be different between the samples and it is of greater significance than a larger difference of a single example that may be one-off and atypical. It is rare to find only one example of a consistent difference between two samples of writing. Normally, there will be far more differences between one in the writings of two people and none in the natural writings of one person. 

Some authors have written on the subject of distinguishing between signatures executed at one and the same time and those executed at different times. Diversity notwithstanding like many other questioned document problems the question is usually one of authentication, fabrication or alteration. This requires a study in search of evidence that signatures, writings or entries, purportedly made on different and separate occasions were, in fact, written at one and the same time or made on a single occasion were, in fact, the products of separate writing instances. There is also some diversity in the manner in which authors refer to the two writing circumstances. Some use the terms single entries and multicentre, others use the same time and different time. Some call them periodic entries, others prefer to say made separately or made sequentially. Even the more ambiguous terms like continuous and uninterrupted and their antonyms are occasionally employed. 

CONCLUSION

Natural variety is how a person writes and rights his name at different times. The following are some of the elements that produce natural variation,

• Humans are not machines.

• Natural variety is an inherent feature of a writer's work handwriting.

•It's a symbol of trustworthiness.

The master pattern of handwriting reveals the variances in wording from one word to the next handwriting and can aid in the differentiation of one handwriting from another. The master pattern is meticulously designed, as are all of the initial, middle, and terminal patterns. In the master pattern, letters are learned. Other aspects include slant, relative size, alignment, and line quality. Important for comparing handwriting.
