Product overview

Luminova ink for screen printing using “Luminova Phosphorescent”, long lasting luminescence time pigments.


  • Glow in the dark sign, emergency sign (emergency exit, emergency stairs, emergency kit, etc.), decorations, etc.
  • Clock-face

Features, Function

  • Compatible with various types of UV and Solvent type screen inks by color matching.
  • Significantly longer afterglow time than phosphorescent ink and contains no radioactive substances


  • 5 to 10% (Please refer to the solvent listed in the catalog for each ink type)
  • *Stir well before every use, as phosphorescent pigments have a tendency to settle.


  • Lower than 150 mesh(Coverage is about 2 to 3 m2/kg with triple print at 100 mesh)
  • *Maximum afterglow brightness is achieved at ink layer thickness of 400μm.
  • *Select the mesh and emulsion thickness so that the ink layer thickness is at least 100-150 µm.
  • *Triple print using 100 mesh stencil can produce ink layer thickness of about 150 to 200µm.

Drying, Curing

  • According to each ink type.


  • This product has tendency to precipitate due to high specific gravity of the pigments.
  • Stirring ink every week or two will prevent precipitation.
  • Ink shelf life: 3 months from production date, unopened.


  • Please refer to respective ink catalog for transportation information.


  • For flammability and flash point, please refer to the product catalog for each ink used.
  • Use safety gloves and eyeglasses to protect skin and eyes. If the ink comes in contact with skin, wash with soap and plenty of water (or lukewarm water) and consult with a doctor.
  • Containers should be closed tightly after use and stored in a cool and dark place.
  • SDS is available upon request. Please request a copy and read it carefully before handling the products.

What is Phosphorescent ink?

Phosphorescent ink contains pigments with luminescent properties that absorb and accumulate light rays from the sun, electric lights, etc., and gradually emit them, so the absorption-accumulation-emission process can be repeated many times. It can also be applied to safety and energy saving measures.
