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 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.
