The age of digital printing has complicated the task of forensic document examination in two significant ways. In the case of document falsification and verification, the widespread availability of sophisticated hardware and software tools (and knowledge to use them) for imaging, manipulation, and duplication has made it difficult if not impossible to detect counterfeiting without equally powerful equipment and know-how. Where a document has been identified as a fraud, or where the pedigree of a valid one is required, traceability to the printing source is critical for successful prosecution. The equivalent of a fingerprint for the printer must be identified, and matched to the source from either a database or the suspect device.

Objective, quantifiable image quality analysis provides a means to achieve these objectives. Powerful image analysis algorithms combined with flexible imaging hardware and instrumentation offer the tools required to analyze documents and establish defensible curricula vitae.

  • For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
