Leveraging Kodak Flexo Technology to Print Touch-screen Sensors

In a huge manufacturing building in the Eastman Business Park in Rochester, New York, Kodak is printing sensors that can be used in touch screens for tablets, computer screens, kiosks, and industrial equipment. The process uses technologies that print service providers will find familiar, but they are being used to achieve a very different end result.

First, a series of flexographic plates are imaged on a modified Creo square-spot plate imager. Each plate has a repetitive design of extremely thin parallel lines. The plates are mounted on a modified roll-fed flexographic press that prints with a catalytic ink on both sides of a roll of clear plastic (similar to the material used for motion picture film). The catalytic ink provides a receptive surface for the next step, in which the printed roll of plastic is immersed in a bath with a copper fluid solution. In that bath, copper is applied to the thin printed lines of catalytic ink. The copper is what makes the resulting print conductive, and that’s why you can make touch screens with this printed component. A darkening agent is applied on top of the copper, and the rolls are then cut into sheets containing the functionally printed sensor that will ultimately go into a touch-screen display. This printed grid of thin, crisscrossing lines is virtually invisible, yet it provides the underlying conductive foundation that is able to sense when someone puts a finger on a touch-sensitive screen.

Kodak, Re-Focused for 2013: Well Positioned to Advance in Digital Print for Packaging

This week Kodak made news with the announcement by CEO Antonio Perez that his company will focus on commercial, packaging, and functional printing. The choices are not surprising, given prospects now for conventional document printing (down) and for “unconventional” printing such as packaging and labels (up). Kodak is fortifying for life after its planned exit from Chapter 11 next year and has made good choices, all markets where there is still growth for digital printing.
