| Summary: | Micro-contact printing (μCP) is an outstanding surface patterning technique in micron scale and, also in
nano scale. Surface science communities such as engineers and biologists have been promoting attention in μCP
and, therefore enriching in improvement to the μCP process itself. However the process is relatively slow in
production. In contrast, flexographic technique is a high speed roll to roll process, but low in resolution and still
has limitation in printing of micro-scale size. Now a day, low cost fabrication is keys to the successful introduction
of printed electronics and roll to roll manufacturing processes. Therefore, study to extend flexographic into the
micro-scale size resolutions, may provide an economical commercialization path for electronic devices, given the
fact that flexographic is a high speed technique commonly used for printing onto very large area flexible
substrates. Although low resolution and poor registration are characteristics of today's flexographic process, it has
many potential to realize fine solid line micro size by combining it to micro-contact printing because both of them
having similarities in method of carrying printed pattern to a substrates. This work have demonstrated that a 10μm
line with 10μm gap was successfully printed by these two combinations of printing techniques, using graphic ink
and biological ink which is Fetal Bovine Serum. |
