Erasure of a writing using rubber is called :

Exam Year(s)

UGC NET - 2012,

Answer: A

The erasure of a writing using a rubber is called mechanical erasure, option A. A rubber removes the writing by rubbing off the ink or the pencil from the surface, together with some of the paper fibres, which can leave signs of abrasion that the examiner can see. A chemical erasure (D) uses a chemical to bleach or remove the ink, and the terms soft erasure (B) and hand erasure (C) are not standard names for the methods. Mechanical erasure can be recognised by the roughened paper surface, the disturbed fibres, and the thinning of the paper, which can be studied under oblique light and a microscope.

The author of the book entitled "Suspect Document" is

Exam Year(s)

UGC NET - 2013,

Answer: C

The book "Suspect Document" was written by Wilson R. Harrison, a British document examiner, and it is a standard text on questioned documents.

Osborn and Osborn are known for "Questioned Documents" and "The Problem of Proof", Ordway Hilton for "Scientific Examination of Questioned Documents", and R.A. Huber for work on handwriting identification. Each of these is a document-examination author, which is why they are plausible distractors, but none of them wrote this particular title.

When two sets of writings / signatures are exactly superimposing upon each other, that means

Exam Year(s)

UGC NET - 2013,

Answer: C

Two writings or signatures that superimpose exactly upon each other mean that one is a traced forgery, because no one reproduces their own writing so exactly twice, as natural variation is always present.

Disguise and freehand forgery would not give an exact overlay, and a simulated forgery imitates a model by eye and shows differences from it, so only tracing gives an exact match. Examiners therefore look for exact overlay, indentations from a tracing point and pen lifts as signs of tracing, while genuine writing always shows small variations.

Kromekote paper method is used in the following :

Exam Year(s)

UGC NET - 2013,

Answer: A

The Kromekote paper method is used to determine the sequence of intersecting strokes. A sheet of glossy Kromekote paper is pressed on the crossing and lifts the ink so that the order in which lines were written can be seen.

Indented writing is deciphered with oblique light or ESDA, invisible writing with chemical or optical methods, and erased writing with infrared or similar techniques.

The following method is nondestructive technique for ink identification :

Exam Year(s)

UGC NET - 2013,

Answer: D

Videospectral analysis examines the ink with light of different wavelengths without altering the document, so it is nondestructive. Solubility tests and thin layer chromatography need a sample of the ink to be removed from the paper, and UV-Vis spectrophotometry as normally applied needs the ink dissolved in a solvent, so these destroy part of the writing. The videospectral comparator is therefore the answer.

Taggants in ink are

Exam Year(s)

UGC NET - 2013,

Answer: D

Taggants are compounds that are added to ink to act as markers, so that a particular ink or batch can be identified later. They are not the pigment (the colouring matter), the vehicle (the liquid carrier) or the binder (the material that holds the pigment to the paper). The last option states the correct definition.

To decipher indented writings, following instrument is used :

Exam Year(s)

UGC NET - 2013,

Answer: B

Indented writing, the impressions left on a sheet below the one written on, is made visible by the Electrostatic Detection Apparatus (ESDA), which uses a charged film and toner. A videospectral comparator examines inks, a universal projectina is an enlarging projector for documents, and the comparison microscope compares two specimens side by side. So ESDA is correct.

Arrange the following in ascending chronological order of their appearance :

(i) Manual type writer
(ii) Laser printer
(iii) Dot-matrix printer
(iv) Inkjet printer
Codes :

Exam Year(s)

UGC NET - 2013,

Answer: A

The typewriter came first, then the dot-matrix printer (1970s), then the inkjet printer (about 1976 for the first commercial models) and then the laser printer in wide use (1980s). So the order is (i), (iii), (iv), (ii), and the options that place the laser printer earlier, or the typewriter later, reverse this.

Match the following :

List - IList - II
a. Watermarksi. Ink examination
b. Poroscopyii. Fingerprints
c. Thin Layer Chromatographyiii. ESDA
d. Indented writingiv. Paper

Codes : a b c d

Exam Year(s)

UGC NET - 2013,

Answer: A

The correct matching is watermarks with paper (iv), poroscopy with fingerprints (ii), thin layer chromatography with ink examination (i) and indented writing with ESDA (iii). Watermarks are features of paper, poroscopy studies the pores in ridges of a fingerprint, TLC separates the dyes of an ink and ESDA reveals indented writing. So iv, ii, i, iii is right.
