Photographs Their only job is to mate with the queen. 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. For example, forensic examiners may be alerted to the possibility of attempts to disguise writing if the pen strokes stop at inappropriate locations or there is evidence of a tremor. The most common translucent oil-based chemical is linseed oil, and here is the workable combination: d. Translucent Chemical For Watermarking with Laser Printers. Signatures Abstract. Thickness may be measured by using paper calipers or micrometers, while weight may be measured by using a very sensitive scale. They are just an overlay or overprinted form of pattern. d. Infrared analysis. The measure of the "degree of whiteness" of a light source as compared to a hypothetical source of perfect white light. a.
