Forensic Printing Process Identification

taught by Joel Zlotnick

Course description

Welcome to Forensic Printing Process Identification!  

For detection of counterfeit documents, printing process identification is a critical skill. Printing technologies such as letterpress, intaglio, offset lithography, inkjet, toner and screen printing all work differently to deliver ink to paper. Under magnification, each printing process displays its own microscopic characteristics that can be recognized using the right lighting and magnification.

Forensic Printing Process Identification contains hundreds of magnified images of security documents like banknotes, travelers checks and stock certificates that were captured using a professional-grade forensic imaging workstation. Course users can control the lighting conditions to inspect hundreds of different example documents, and choose between incident, oblique and transmitted light to see the unique print characteristics in each example.  

Forensic Printing process is very comprehensive!  Here's the full outline of the course topics:
