Abstract
Very little attention has been paid in the literature to the impact of
the drop size on the dynamics of spreading and on 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
upwards,
by using a special high speed imaging environment and continuous ink jet
(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 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.
