Abstract
In graphics, gravure printing is the
preferred method for printing high quality, fine
dimension graphics using high-speed roll-to-roll or
sheet fed presses. Gravure printing typically employs
flexible and compressible substrates such as various
papers and polymer films. In electronics, glass
substrates are a common, if not preferred, substrate in
many applications, particularly displays and
photovoltaics. In combining printing with glass
substrates, challenges exist in adapting contact-based
printing methods such as gravure to the mechanical
properties of the more rigid substrates. In this work,
sheet-fed gravure printing has been successfully used to
print silver-based conductive inks on glass substrates.
Various features were designed and printed to evaluate
conductive layers in terms of their printability and
electrical performance. The independent variables
include gravure cell dimensions, trace orientation with
respect to printing direction and ink type. Results from
this work provide an insight into the science of gravure
printing on glass by correlating the independent
variables to printed feature quality and electrical
performance.
