Metallic Effect

These inks produce a shiny metallic effect. We offer a wide variety of metallic effects which differ primarily in terms of color, particle size, gloss or matt level and abrasion characteristics.

These inks can be easily processed up to a particle size of 20 μm.

The color palette ranges from silver to gold to copper. With the addition of glossy color shades, additional eye-pleasing effects can be achieved.

Typical markets include:

  • creative and technical fields,
  • gastronomy products
  • scales
  • labels
Glitter Effect

Glitter effect is achieved by adding polyester particles (“glitter) to ink.

The most popular options are silver, gold and iridescent glitter.

The glitter particles are up to 50 μm in size and reflect the light depending on their color, amount and size. With dark backgrounds the glitter effect is intensified.

UVA Glow Effect

UVA glow effect is achieved with an additive which can be added to any ink.

Available as standard with a blue effect under UV light. This user friendly ink is also available in other shades on request.
