Studies on Inkjet Ink with Confocal Raman Microscopy
Abstract:The chemical properties of ink, substrate and the interface between them influence the printing process and the achievable printing quality. Several methods to characterize these properties are developed and used in the recent years. The usage of vibration spectroscopy methods are opening a new way to characterize printouts on the molecular level. The raman spectroscopy, mainly working with visible light and a low level sample preparation, has a high potential in this field. Starting with chemical characterization of the composition up to using this method as an online observation tool in printing systems, a wide area of applications is thinkable.
This work presents the first results of using a confocal raman microscope to characterize oil and water based inkjet inks on different substrates. Using the proper measurement parameters, we were able to observe the spreading and penetration of the ink into the substrate. Further work shows the possibility of using the results for three dimensional ink distribution analyzing.

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.
