A team of Finnish scientists has found a new way to examine the ancient art of putting ink to paper in unprecedented 3-D detail. Using x-ray and laser-based technologies, the researchers created a nano-scale map of the varying thickness of toner ink on paper. In general, toner thickness was dictated mainly by local variations in roughness rather than local variations in glossiness. The technique could improve scientists' understanding of how ink sticks to paper and ultimately lead to higher quality, less expensive and more environmentally-friendly printed products.
