| 1. A method comprising:
providing at least one array of tips;
providing at least two patterning compositions different from each other;
ink jet printing at least two of the different patterning compositions onto at least some of the tips; and
depositing at least some of the ink jet printed patterning compositions onto a substrate surface;
wherein the array of tips and the ink jet printing are adapted to prevent substantial cross-contamination of the patterning
composition on the tips.
