DEFINITION

Classification: 427/466

Nonuniform or patterned coating (e.g., ink jet printing, etc.):

(under subclass 458) Processes wherein the coating utilizing electrostatic charge, field, or force is (1) applied only to selected portions of a base (2) applied in such a manner as to produce a coating of uneven, discontinuous, or nonuniform thickness, or (3) varied from area to area as to physical or chemical properties.
