Clarity Watermark Fluid



Clarity was developed at the request of the American Philatelic Society (APS) for an improved watermarking fluid that is safe to use with philatelic materials. Clarity combines superb optical resolution with a moderate evaporation rate in a solvent free, non-hazardous formulation.

  • Crystal clear resolution
  • Lasting images
  • Non-toxic, non-flammable
  • Safe for adhesives, inks and taggents


Place stamp face down in a standard tray and apply a few drops of Clarity. Watermark will be visible, if present. Always handle carefully with tongs to avoid soiling and tearing. Remove stamp from tray and place on a clean surface until fluid evaporates (less than one minute).
