Solution of getting strong retro reflective:

a. Ink must be clear and transparent, Grey. Yellow. Red will be better.

b. Firstly ,print aluminum powder as foundation. Then print with the mixture of ink and glass bead.(Aluminum coated glass bead need not)

c. Make the glass bead on the paint surface as more as possible.(ND2.2 glass bead need not)
