Silver nanoparticle inks are printed on nine papers as well as a polyimide film. Structure width and edge raggedness is evaluated on each substrate for both polar and non-polar ink. The substrates are characterized in terms of material content and various physical surface properties. The aim of this study is to establish relevant correlations between printed structure measurables and surface properties, in order to expand the understanding of the mechanisms involved in nanoparticle ink - paper surface interaction. A multivariate analysis is presented which reveals correlations between print performance and paper properties, as well as relations between different paper properties. The results suggest that besides surface energy considerations, absorption rate and surface roughness play important roles for achieving well behaved print structure definition in paper electronics applications.
