Abstract
Described herein are capacitive devices and methods for producing same using printing methods such as flexography, gravure, offset, lithography, etc. The capacitive devices are formed from printing conductive inks, non-conductive inks, masking ink layers, graphic artwork layers, and overprint layers on a substrate. Interaction between a conductive ink layer of the capacitive device with a touch screen device of a computer, tablet, smart phone, etc. causes a capacitive effect that allows information coded in capacitive device to be read, leading to an activity such as the download of content to the device having the touch screen.
