Banding in tonal areas is a common problem for many printers, especially in the Narrow Web industry. These bands of alternating high and low ink density are shown below. This defect has many causes, including machine vibration as well as image layout on the plate.

In order to eliminate the problem of gear banding, we recommend using SA2000 open-cell urethane cushion mounting tape. This provides unequaled energy absorption that eliminates the banding defect in most situations. Compared to closed-cell polyethylene foam mounting tapes, open-cell better prevents plate bounce and dissipates vibration resulting in noticeably more uniform tonal areas.
