There are typically two different forensic methods for ink dating. With this method the forensic analysis determines the components in the ink, compares them against a library of standards and then allows an opinion regarding the first date that particular ink was manufactured commercially available. The dynamic approach is very useful in determining if a pen ink was placed on a document on its purported date, i. There are only a handful of forensic scientists capable of performing these tests and laboratories equipped with the proper tools. The proposed tests are minimally invasive, the latter two involving the placement of pinhole perforations in the text, paper and signatures on the Original Document. The pinholes themselves are not typically easily visible unless the document is held up to light, and the testing has no negative effect on handwriting analysis. All of the proposed testing follows Court approved testing methods, e. Under appropriate circumstances, the Court may order destructive testing of all or some portion of the physical item in question. Douglas E. Barnhart, Inc.

PAPER FORENSICS & AGE DATING

Yes, with certain limitations. We can determine the first date of commercial availability of the ink used to prepare any handwritten or handprinted material. The type of ink does not preclude this examination. If the initial date of commercial availability is more recent than the supposed date of the examined writing, then the document is not what it purports.

We cannot, however, through this technique, determine the specific or even approximate date of preparation. Other techniques can determine the approximate date of preparation of handwritten entries.

While the type and age of the paper can help determine the authenticity of a print, it is not in and of itself proof. Some forgers use old paper.

There are four major approaches each approach is a group of methods used for dating inks on documents:. Other ink entries are not necessary for comparison. Aginsky has developed the SET as a result of many years of research of the ink aging methodology developed and published by Dr. Antonio A. Cantu in the s.

The second ink dating approach analyzes the chemical composition of inks on a contested document with the aim to determine whether these inks as well as other materials used to produce the document — paper, inkjet printing ink, toner, stamp pad ink, etc.

Methods for Estimating the Due Date

Ink Dating is done in two primary forms. The first ink dating method is the static approach, which determines when the ink being examined was manufactured. The second ink dating method is the dynamic approach, this method is to determine when the writing occurred, or in simple terms, how long the ink has been on the paper. The ink dating static approach is typically more useful as the difference between the date on the document and the present time increases.

Several different tests exist in this form of ink dating.

Radiocarbon ages of 17 ancient Japanese documents of known age and 3 unknown samples were measured by AMS. Radiocarbon dating on the known documents concluded that the Japanese paper is a suitable sample for radiocarbon dating because of small discrepancy between the calibrated radiocarbon age and the historical age due to the characteristics of Japanese paper. From the dating of the paper samples of unknown age, the wood-block prints, it was clarified that they had been produced between the 11th century and the first half of the 12th century as the historical information suggested.

One of her recent illustrations depicted her rendition of “Clippy,” the Microsoft paper clip — notorious for popping up whenever you didn’t need him, offering suggestions you never asked for. He eventually took the hint and I never heard from him again. Though the term paperclipping is new, Carla Marie Manly , a clinical psychologist based in California, says this pattern of behavior — dropping off the face of the planet after a few dates only to follow up months later to see if they’ll still get a response — is not.

Radioisotope dating has revealed that the age of the Earth is – billion years, and In this paper, a different approach to solving the problem is proposed.

Ink Dating Expert Witnesses

More recently, a plethora of market-minded dating books are coaching singles on how to seal a romantic deal, and dating apps, which have rapidly become the mode du jour for single people to meet each other, make sex and romance even more like shopping. The idea that a population of single people can be analyzed like a market might be useful to some extent to sociologists or economists, but the widespread adoption of it by single people themselves can result in a warped outlook on love.

M oira Weigel , the author of Labor of Love: The Invention of Dating , argues that dating as we know it—single people going out together to restaurants, bars, movies, and other commercial or semicommercial spaces—came about in the late 19th century. What dating does is it takes that process out of the home, out of supervised and mostly noncommercial spaces, to movie theaters and dance halls. The application of the supply-and-demand concept, Weigel said, may have come into the picture in the late 19th century, when American cities were exploding in population.

ink and paper we can estimate the age of the document. Along with it, the chemical constitution of the material can also be estimated by the Ink Dating Method.

The Shroud of Turin , a linen cloth that tradition associates with the crucifixion and burial of Jesus , has undergone numerous scientific tests, the most notable of which is radiocarbon dating , in an attempt to determine the relic ‘s authenticity. In , scientists at three separate laboratories dated samples from the Shroud to a range of — AD, which coincides with the first certain appearance of the shroud in the s and is much later than the burial of Jesus in 30 or 33 AD.

The idea of scientifically dating the shroud had first been proposed in the s, but permission had been refused because the procedure at the time would have required the destruction of too much fabric almost 0. The development in the s of new techniques for radio-carbon dating, which required much lower quantities of source material, [8] prompted the Catholic Church to found the Shroud of Turin Research Project S.

The S. Dinegar and physicist Harry E. Gove consulted numerous laboratories which were able at the time to carbon-date small fabric samples. The six labs that showed interest in performing the procedure fell into two categories, according to the method they utilised:. To obtain independent and replicable results, and to avoid conflict between the laboratories, it was decided to let all interested laboratories perform the tests at the same time.

In , the S. However, a disagreement between the S. A meeting with ecclesiastic authorities took place on September 29, , to determine the way forward. In the end, a compromise solution was reached with the so-called “Turin protocol”, [14] [15] which stated that:.

The relative and absolute age of roller and gel ink entries determined by gas chromatography GC and UV-vis methods are presented in this paper. The relative age of ink entries is concluded by the comparison of solvent amount between questioned and known dated entries. Absolute age of ink entries is estimated through the changing ratio of solvent components between heated and unheated samples without known samples for comparison.

The methods are accurate and reliable.

The chemical analysis of writing and printing inks, as well as paper, can be invaluable when trying to prove whether a document is fraudulent. Ink dating is a highly specialized forensic examination and considered to be one of the most accurate and reliable methods to help determine the age of a document. An ink formulation can be identified to a specific manufacturer to ascertain the first date of commercial availability.

If an entry is dated in , but the ink was not available until then the document could not have been created in Inks contain chemical solvents that evaporate and generally go through a drying process that can last up to 2 years. Comparing Writing Inks. Chemical analysis can be conducted on a suspicious entry to determine if it is consistent with other associated or surrounding writings. Multiple inks can be chemically compared with each other to corroborate or refute whether the entries were created contemporaneously or produced over multiple periods of time.

Forensic Analysis of Printers and Copiers. Ink analysis and dating can also be conducted on machine printed document such as inkjet ink and toner from photocopiers, laser printers, and facsimile machines. Forensic Paper Examination. Gerald M. LaPorte, M. He trained with and served as the Chief Research Forensic Chemist with the United States Secret Service and was responsible for maintaining the largest known forensic collection of writing inks in the world.
