Abstract
A method of fabricating an organic electronic device using ink jet printing in swathes, comprises depositing an ink into a first set of locations in a column in a first print pass; wherein the first set of locations is less than a total number of locations in the column; and depositing an ink into a second set of locations in the column in a subsequent print pass; wherein the second set of locations is less than a total number of locations in the column. Preferably the number of nozzles used to fill all locations in a column is equal to the number of print passes needed to print the column. All locations in the swathe are printed after all print passes using a regular repeating randomized pattern, such that be ensured that print locations are not under filled, or over filled.
