Reflective Ink Instructions
Mixing Instructions:
a. Choose neutral transparent printing inks
b. Choose glass bead with small particle size like 20~40um, 40-60um , 50-75um, 60-90um
c. Add about 50-100% of glass bead, by weight, into the clear printing ink.
d. You could add more if brighter ink is required. Adding more powder thickens the solution.
e. Do not grind the glass bead
f. Use any containers and stir the mixture at high speed.
