09-05-2022

Luminous Printing Ink is the Product of Luminous Pigment with Clear Printing Inks. Luminous Printing Inks can glow in the dark for hours after absorbing surrounding light. With good heat resistant and anti friction properties, these inks are suited for application on many materials like paper, textile, wood, plastic, metal, ceramic, etc..

 

Mixing Instructions for Luminous Printing Ink

a. Choose neutral transparent printing inks

b. Choose pigments with small particle size like 20~60um, 40-80um

c. Add about 20~50% of luminous pigment, by weight, into the clear printing ink.

d. Mixing ratio for UV light sensitive powders is only 15 to 25%, measured by weight, to the clear resin.

e. You could add more if brighter ink is required. Adding more powder thickens the solution.

f. Do not grind the pigments.

g. Use containers with ceramic or glass interiors and stir the mixture at high speed.

h. To avoid deposits, you should use high viscosity resins or anti-settling agents.

i. Do not use heavy metal components as additives.

j. Select a printing ink that is suitable for the surface it is to be printed on. For example, use metal abrasive oil it the surface to be printed on is metal.

Usage Instructions for Luminous Printing Ink

a. Viscosity of mixed inks should be between 3000-5000 poise.

b. Viscosity can be adjusted during the printing process with a diluting agent.

c. A base coat of white or very light color is preferred. Applying luminous paint on dark colors reduces the glow effect by as much as 50%.

d. For good luminous effects, the luminous layer should be at least 100-150um.

e. Ideal mesh size for silkscreen printing screens is 80-100 mesh. Smaller screen mesh size are okay as these create a thicker printed layer.

f. One kilogram of Luminous Powder can be mixed to produce up to 2-3 litres of glow paint.

g. One kilogram of Luminous Powder can be mixed to produce up to 3-4 litres of luminous ink.

h. One litre of ink can cover an area of about 3.5 square meters.

i. Special luminous pigments are required for water-based printing ink
