The printeG electronics market, accorGing to market research ?rm ,DTech(x, is slateG to grow from $16.04 billion in 2013 to $76.79 billion in 2023. Printing transparent griGs with a known printing process such as Aexography is attractive to this market because transparent grids are part of the fast-growing touch screen market (amongst others�, and Aexography offers a lowcosthigh-volume print platform that can handle a variety of substrates, high press speeds, roll-toroll (R2R) printing, and the ability to handle different ink rheologies. However, Aexography has print characteristics that can be problematic for printed electronics such as high image (feature) gain and the ability to hold ?ne images (features) in the (relief) printing plate. This study used a "banded" anilox roll, which has multiple volumes and cell counts separated into bands, conductive nano-silver, water-based ink, and a PET substrate and printed on a commercial Aexo narrow- web press. The process parameters studied included types of sticky back, anilox cell count/volume, plate imaging, and plate surface morphology. The printed transparent grid patterns were evaluated for conductivity, which was measured with a Digital Multimeter; and transparency, which was measured with a transmission densitometer. The results of the study showed that when the photopolymer plates were imaged at a resolution of �000dpi and with a "Aat top dot" (1�1 ?le ± image) exposure techniTue, the Aexo plate was able to hold a minimum of 6.3� microns line width. The 6.3� microns lines were successfully printed on the press and produced the conductive lines. Types of sticky back and different anilox cell volumes have an impact on measured resistance of the grid pattern. $ high modulus, or "?rm" sticky back tape with a low screen count/high-volume anilox (800 cpi/2.85bcm) resulted in the lowest (<15 ohms) resistance. In addition, the introduction of plate surface texture during
