Excerpt from Ink and Questioned Documents
In the natural course of events a fraudulent document is usually manufactured only a short time before it is actually brought forward. The conditions often require that such a paper be dated back a year or more and, as stated,if it can be shown that it could not at most be more than a few days, weeks, or months old, the document by this means alone may be utterly discredited. That ordinary writing ink is of an entirely different color when first written with than that which it finally reaches is well known, but this is about all that is generally known on the subject. It is important to know the rate of development and when such changes are completed.
After ordinary writing ink reaches its fullest intensity of color it remains in a practically fixed condition for some years, six to ten, and then it begins to show slight dis coloration on the edges of the pen strokes that is the result of age. This discoloration or yellowing is progressive until after a sufficient lapse of time, depending upon conditions, the ink finally becomes a yellowish brown color.

Paperback. Zustand: New. Print on Demand. This book examines how iron-nutgall Ink, commonly used in many documents throughout history, changes color over time.

The main subject of the book is the author's development of a color microscope, used to examine ink's tint and shade. Through the use of this device, the author demonstrates that iron-nutgall Ink's color can be measured and recorded, allowing for a more objective and precise way to determine the age of a document. This book is an excellent resource for anyone interested in document analysis, offering a detailed examination of the author's research and a valuable new tool for experts in the field.
