Latent images

Latent images are a special case for structures.
Parallel lines are applied to different parts of a subject at different angles and/or different distances and/or thicknesses.

  • They are not visible to the trained eye and become apparent only at particular angles and light incidences.
  • Therefore perfect for high quality security cards e.g. bank cards, national ID’s,…
  • The lines’ different designs, distances an angles influence the visibility.
