The goal of spectral encoding is to provide a limited dimensional space that preserves as much information about the original reflectance spectrum as possible. Recently, several spectral encoding techniques have been suggested by Nakaya and Ohta, as a simplified improvement over the LabPQR spectral encoding technique. To directly compare the reproduction accuracy between the new techniques and LabPQR a technique was developed to quantify the accuracy of three spectral encoding algorithms. Thousands of random spectra were generated and converted using the three spectral encoding techniques into six dimensions. The six spectral encoded values were then used to regenerate the target spectra. Simple RMS difference, Delta E 2000, and Delta E 2000 under a different illumination was used to evaluate reproduction quality. It was found that the LabPQR technique maintains higher reproduction capabilities than the alternate techniques.

  • 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.
