Fusing Parameters Effect on Gloss
In this work, fuser effects on gloss have been studied and analyzed using two current HP Color LaserJet (CLJ) printers, the CLJ4700 and CLJ4650. These products differ in their fuser design, toner formulation, and gloss performance. To study the fusing parameters that affect gloss, the contribution of the fuser designs, fuser control conditions, and toner type were separated out by using an independent fusing system that allowed samples created in the two different printers to be fused using a common process. An experimental approach was used to build a foundation for developing a physical model of the fusing process.
The toner type was found to have the largest effect on gloss. The toner type effect on gloss can be credited to the rheological properties of the toner. Image density was the second largest effect on gloss and can be categorized by three regions: 1) low density (substrate dependent), 2) medium density (pattern dependent), and 3) high density (fusing process dependent). Nip duration, pressure, and temperature are secondary design variables that should be used to further optimize the fusing system, especially for high density images, once the fuser physical design and toner formulation are fixed.

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.
