Simultaneous Printing of Conductive Pattern with Different Line Width Using Soft Blanket Gravure Printing Method

Abstract

We have developed a new printing technology called “Soft Blanket Gravure (SBG)” printing, which is able to print patterns onto curved or three-dimensional object surfaces using a thick and soft offset blanket (called a “soft blanket”). We have found that SBG printing can print silver inks under various conditions where conventional gravure offset printing cannot typically print. In particular, SBG printing can print wide interconnects with widths of several millimeters. We have also succeeded in simultaneously printing interconnects that have widths of 50-1,000 micrometers on a glass substrate.
