| 9. An integral orifice array plate and charge plate for a continuous ink jet printer print head, comprising:
a. an orifice plate having:
an electrically non-conductive orifice plate substrate,
a trench of predetermined depth on one of two opposed sides of the orifice plate substrate, and
an array of orifices through the orifice plate substrate from the trench to the other of the two opposed sides, said orifices
being spaced apart by a predetermined distance; and
b. a charge plate having:
an electrically non-conductive charge plate substrate of predetermined thickness, and
a plurality of charging leads on one of two opposed sides of the charge plate substrate, said charge leads being spaced apart
by said predetermined distance, wherein the other of the two opposed sides of the charge plate is anodically bonded to said
one side of the orifice plate substrate such that the charging leads align respectively with the orifices of the array and
are spaced there from by the depth of the trench and the thickness of the orifice plate substrate.
