This work examines the technical challenges facing the security print business sector. This sector includes a wide variety of printed marks along with print-as-fabrication, covering a wide gamut from barcodes to interactive holograms. As a result, this work also highlights opportunities for printing and fabrication technologies.

This conference is an ideal opportunity to explore specific opportunities in the physics, chemistry and material science of security printing and to consider new hardware and software applications for print inspection and verification.

The security print application space is very much wider than the obvious ones of identification verification documents, such as passports and identity cards. It now covers brand and asset protection plus a host of emerging actionable printing applications.

Security printing can be a part of every printed item. The very printing process itself results in the unpredictable deposition of marks which can be used for forensic identification. Complex color images can be used to identify the print shop which printed an item, due to nuances of color, variable and customized printing. Intentional data can be printed in the form of barcodes, graphical alphanumerics (such as guilloches), and a host of fabrication processes – such as lenticular, adhesive and stereolithographic processes – can be used to create difficult to mimic content that can be used for overt, covert and/or forensic security features.

More about this publication?
  • 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.
