More recently, watermarks or shaded marks, were sometimes applied with a dandy roll impression. The dandy roll compresses the fibers in a given region producing an opaque design. Watermark patterns can be seen in Transmitted light, Raking light, and by low energy Radiography such as soft or Grenz radiography and Beta radiography .
