While differentiation among inks can be accomplished by visual examination, nondestructive, and chemical tests, positive identification of the specific source of the ink (i.e., the exact pen) is unlikely. Research has also found that faxes may undergo significant dimensional changes that can result in changes in size or even distortion, further complicating the investigation of transmitted questioned documents. For a discussion of the technical aspects of the medium . A side-by-side comparison can then be conducted with the questioned impression, and conclusions as to the source of the impression may be made. Abstract The questioned document examiner studies letter design and size on two or more documents.

For example, it may be the case that a page is substituted in a will that is printed on paper or with ink that was not available at the time of the original signing. More recently, an instrument known as an Electrostatic Detection Apparatus, or ESDA, is used to produce a visual image of the indented writing on transparency film. b. b. Macro lens Q. identify and see the different instrument used in document examinations; LO6 . A. The increasingly ubiquitous use of computers resulting in computer-generated documents has resulted in difficulties for the questioned document examiner. An individual attempting free-handed simulation of writing strives for both accuracy of shape and proportion, and fluency of line; however, it is nearly impossible to achieve both. This depth is visible as a shadow in low degree illumination. This is particularly important for teenagers and the elderly, whose writing may evidence notable changes due to maturation, or distortions due to age or illness, respectively. var cid='9204290220';var pid='ca-pub-8871633933419324';var slotId='div-gpt-ad-forensicreader_com-medrectangle-3-0';var ffid=2;var alS=2021%1000;var container=document.getElementById(slotId);container.style.width='100%';var ins=document.createElement('ins');ins.id=slotId+'-asloaded';ins.className='adsbygoogle ezasloaded';ins.dataset.adClient=pid;ins.dataset.adChannel=cid;if(ffid==2){ins.dataset.fullWidthResponsive='true';} An UV bandpass filter mounted on the camera .

Thus, it is important that obtained writing specimens be taken from around the time of the questioned document. a. They use specialized chemicals with a refractive index similar to cellulose and make impregnated areas translucent. Another way to trace writing is to place carbon paper on top of the original document so that the pressure of the pen will produce a carbon impression upon the lower document. And with digital watermarks, you just need word processing software to create and print them over the paper. discuss the different classification of questioned documents; LO4. Given the poor quality of faxes in general, they are subject to alteration, however, so careful scrutiny should be applied to any discrepancies in pixilation across the document, as well as any variations in handwriting or print type, spelling, punctuation or formatting.
