Applicability of FTIR and Raman Spectroscopic Methods to the Study of Ink Jet and Electrophotographic Prints
Abstract:Vibrational spectroscopic methods are nowadays widely used in the analysis of materials both in xy- and z-directions. Needs to understand durability, especially light fastness, mechanisms in ink jet and toner adhesion mechanisms in electrophotography call for analytical techniques.
Sample sets to study applicability of various FTIR and Raman techniques to ink-paper interaction analysis included ink jet prints exposed to different amounts of light energy, and electrophotographic prints fixed in different conditions. FTIR-ATR and Raman measurements in xy- and z-directions were found to be the most promising techniques, since the differences between the samples were revealed most distinctly. The confocal Raman technique proved to be applicable to depth profiling of colorant and toner. Stepscan PAS can be used for depth profiling of electrophotographic prints.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
