In a print production system, the ability to associate each page with its original electronic form enables a number of important automation services, such as alternate-source page insertion, page/sheet routing and aspects of JDF-compliance. This work demonstrates the efficacy of a method capable of matching a scanned version of an incoming page to an original RIP, and was tested with a library of a thousand sample commercial pages. Frequency domain analysis suggests that low-resolution representations of pages can be used for matching purposes. This notion is corroborated by experimental results; a 98% correct matching is achieved for pages reduced to a bit-depth of 1-bit at only 1 dpi using a simple XOR method, and a perfect matching rate was achieved using pages represented at 16 dpi at a variety of bit depths using a sum of squared errors measurement. The method is implemented without placing any extra ink on each page.

  • 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.
