1. A filter plate to intercept particulates suspended in flowing ink, the filter plate usable with an ink jet head, the ink jet head presenting a substantially axial ink flow path, the filter plate comprising:
a filter substrate having a filter hole region; and
filter holes extending through the filter substrate in the filter hole region, each filter hole including a first part and a second part that are angled with respect to each other so as to have angled line shapes, wherein the angled line shapes are asymmetric with respect to the substantially axial ink flow path.
