#ink analysis

Examining inked writing in conjunction with other techniques (e.g., handwriting analysis, watermark identification) can provide details regarding document preparation. The composition of writing inks varies with the type of writing instrument (e.g., ballpoint pen, fountain pen, porous-tip pen) and the date of the ink manufacture. In general, inks are composed of dyes in solvents and other materials that impart selected characteristics. Ink analysis usually is limited to comparisons of the organic dye components. When ink formulations are the same, it is not possible to determine whether the ink originated from the same source to the exclusion of others. Examinations cannot determine how long ink has been on a document.
