    Abstract

    Reverse-offset printing (RO) is a promising method to fabricate high-resolution line structures using conductive nanoparticle inks. In this paper, a laboratory-scale RO equipment is used to develop a roll-to-roll process. This paper focuses on printability and performance of conductive high-resolution lines. Critical interactions between the ink, plastic substrate and parts of the printing equipment (PDMS blanket and Ni-stamp) are studied. Resolution down to 1 μm is achieved with a homogeneous line edge structure suggesting potential for further resolution enhancements. Conductivity of the printed lines is very close to values reported in literature as achieved using other printing techniques.
