How to Maximize the Registration Accuracy in R2R Processing

High registration accuracy in roll-to-roll (R2R) processes enables high throughput production of complex multilayer devices in printed and flexible electronics. Three different topics need to be optimized, in order to maximize the registration accuracy: i) stability of the substrate dimensions, ii) mechanical accuracy of the printing press, and iii) software to handle the web tension and position. We will show how all of these three topics can be improved to allow 15-20 µm registration accuracy even for rotary screen printing
