The Effect of the Drop Size on the Print Quality in CIJ Printing
Abstract:Only scant attention has been paid in the literature to the influence of the drop size on the dynamics of spreading and the final dot quality with different paper grades. In this study, the development of the image properties was observed on a time scale of a few milliseconds and upward, by using a special high-speed imaging environment (introduced at NIP13) and CIJ printers, with different nozzle sizes but similar water-based ink compositions.
The results clearly show that there is a strong paper-dependent affiliation between the size of the ink jet drop and the high-speed dynamic phenomenon of dot spreading and drying. With coated paper grades, the interrelation between the drop size and the magnitude of the surface structure was found to be important, compared with the final shape of the dot. With uncoated papers, the growth of the dot is dependent on the size of the drop. The final intensity of the print was found to be the outcome of the characteristics of the ink and the absorption properties of the paper.

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.
