Application of Raman spectroscopy and infrared synchrotron radiation for digital print analysis
Abstract:The chemical properties of ink, substrate and the interface between them influence the printing process and the achievable print quality. Several methods to characterize these properties have been developed and used in recent years. The usage of vibrational spectroscopy methods is opening a new way to characterize printouts at the molecular level. The Raman spectroscopy, mainly working with visible light and a low level of sample preparation, has a high potential in this field.
In the present work, the use of micro-Raman spectroscopy and synchrotron radiation-based infrared (SR-FTIR) spectromicroscopy offers a powerful, non-destructive method for the study and the identification of inks on paper and the comparison of them to one another without the need for chemical preparation and related laboratory work.
Using the proper measurement parameters, the 3-D distribution of ink in paper was studied and related to the spreading and penetration of single inkjet droplets. This research was undertaken at the IR beamline at the Australian Synchrotron, Victoria Australia.

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.
