Abstract
I have followed the progress of ink jet technology as the parents watch their child grows up with expectation and have contributed somewhat to the progress. With great pleasure, the child, ink jet technology has been evolving even now. The evolution has two directions as extending capability and getting over weak point in the similar way of nurturing. Namely, the former is expansion of ink jet to various applications using simple process and the later means challenges against performance limitation derived from imaging process achieved only by the interaction between ink and media.
The differences of technical approaches in each direction also exist. Progress of elemental technology region has been noticeable in extend of the possibility and challenge against the limitation has been dazzling in system integration or peripheral technology progress.
I would like to present the status of ink jet technology and the prospects in line with two directions of the progress.
