Abstract

One or more techniques, devices and/or systems are disclosed for mitigating a perceived electrical sensation for a relief print scanning device. A current determination component can be used to identify an electrical current configuration that provides a mitigated electrical sensation to the user, for use with an electroluminescent-based relief print scanning device. The electrical current configuration can be identified using one or more image characteristics of a relief print image, which is captured by the devices using the current configuration. A current adjusting component, can be operably coupled with the current determination component, and may be used to adjust the current configuration, where the adjustment can be based on current adjustment data that is provided by the current determination component, based on the image characteristics.
