Wax paper is a wood-free product with a mostly black underprint and a pressure-sensitive layer applied on top. This layer is opaque, i.e. impermeable to light, and becomes transparent when subjected to pressure, e.g. from metal pins in the recording device. In this way, the underprint appears again. This then results in a typeface that can display a wide range of information. This quality is therefore used as recording paper, e.g. in measuring stations, on the railroads or in older trucks (speedometer discs).
