Abstract

The current analytical techniques for characterizing printing and graphic arts substrates are largely ex situ and destructive. This limits the amount of data that can be obtained from an individual sample and renders it difficult to produce statistically relevant data for unique and rare materials. Resonant cavity dielectric spectroscopy is a non-destructive, contactless technique which can simultaneously interrogate in situ both sides of a sheeted material and provide measurements which are suitable for statistical interpretations, offering analysts the ability to quickly discriminate between sheeted material compositions. In this methodology paper, we demonstrate how contactless resonant cavity dielectric spectroscopy may be used to differentiate between papers of varying fiber species compositions, to determine relative age of paper, and to detect and quantify the amount of post-consumer waste (PCW) recycled fiber in manufactured office papers.
