Streszczenie
Forensic documents examiners may come across questioned handwriting written on unusual writing surfaces with unusual writing devices. Such handwriting may have variations that are beyond the scope of natural variations and pose a challenge to the document examiner. An attempted disguise of such writings and the absence of exemplars written under similar writing conditions may further complicate the comparison process. The present study was based on the examination of writing samples written with spray paint cans on vertical surfaces. A preliminary study was conducted consisting of examining the handwriting of 30 individuals, executed on vertical writing surfaces with spray paint cans, and handwriting written under normal writing conditions. Various writing features were observed to find out the variations between the two sets of writings.
