The preliminary visual inspection of a stamp impression is to examine it microscopically, during which time the examiner may be able to identify a number of factors, including the ink source and condition of the ink die. Silver halide grains It is sometimes possible to remove the obliterating material using an ordinary rubber eraser, chemical solvent or scraping off the overlying layer, although pains must be taken not to damage the underlying writing. These may be manufacturing defects, such as defective die material, distortion, or misalignment, or may be a result of use (e.g., accumulated ink, dirt, or fibers) or misuse. However, there will likely be evidence of laborious production, such as signs of uneven pen pressure, pen lifts, and poor line quality. In printers, they are measured by applying wetting tension liquids to paper in order to analyze print-ability, coating lay down, and heat sealability of treated films. Say a suicide note is found at the investigation scene. Adding new information that was not in the original document or substituting an entire page also may perpetrate fraud.
