Abstract There are a number of plate imaging options for flexographic printing. The type of plate used and the way it is processed affect the trace resolution and ink transfer of the conductive material. The authors have recently completed one of, if not the largest research studies ever conducted in printed electronics. Over 45,000 resistances were measured and nearly 1000 three-dimensional optical profiles were obtained, from which a variety of morphological parameters were measured. Many printing variables were examined, including plate material, imaging and plate processing conditions, trace orientation, anilox cell volume, plate type, line and gap width, and orientation. Aqueous, nano-silver inks were printed on both PET and coated paper. The impact of these printing process variables on the conductivity and resulting printed trace width and minimum reverse will be discussed.
