Comparison of signatures is based on the principle of variation in handwriting as no two signatures are precisely alike. However, due to presence of variation in all handwriting components such as style, slope, slant, alignment, spacing and pen lift, it serves to personalize and identify writing. Therefore, it is essential to resolve these primary elements and habits of writing with an accurate range of variation. In the present study, 3 sample of signature were collected from the 70 persons of Bilaspur district, Chhattisgarh with an attempt to study the variation in repetitive signature of same writer. As a result in a typical state of mind, most of the character and letters were not changed and just a few letters and characters were changed. Thus, it provides evidence of the identity.
