Figure 3

3D contours of the metal concentric rings printed on soda lime coated with a thin layer of 100 nm gold.

Donor layer thicknesses: (a) 300 nm, (b) 500 nm, (c) 750 nm and (d) 1000 nm and gap distances of (1) 100 μm, (2) 400 μm and (3) 1000 μm. (a4–d4) Superimposed line profiles for different gap distance and for each one of the donor thickness (the profiles were taken across the middle of the rings, see black arrows plotted over the 3D contour images which indicate the line profile direction); (e) SEM image of the concentric rings as printed under conditions (b2); (f) Same SEM image at a tilt of 55 degrees.
