Technically it's the watermark, but sadly it isn't hidden. It's just printed at a different resolution that is still visible to the naked eye. That stupid blue "urine" light and my iPhone had a fight and that's the image I was able to capture. I believe there is a watermark or markings that we cannot see with off the shelf light technology.
