Fluorescent Staining Technique for Visualizing Thin Films
This technique was applied to a variety of xerographic carriers to visualize the coating. Changes in processing can be clearly observed. Film thickness down to hundreds of angstroms can be readily observed. Thin discrete films become apparent in this technique and it is ideal for observing powder-coating processes. The technique is applicable to a variety of other applications involving thin films on small irregular surfaces.
The technique was used to measure the coating available for charging on a carrier surface. The carrier charge was proportional to the fluorescent intensity of the polymer on the surface and not the total amount of polymer present.

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.
