Reflective powder can be added into the ink, made reflective ink, screen printing or brushing to fabric or other items. The reflection brightness changes along with the amount of adding powder.

Reflective Ink Instructions

Mixing Instructions:

1. Choose neutral transparent printing inks

2. Choose reflective powder with small particle size like 20~40um, 30-45um,40-60um , 60-80um

3. Add about 30~50% of reflective powder, by weight, into the clear printing ink.

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

5. Do not grind the reflective powder

6. Use any containers and stir the mixture at high speed.

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

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

If the surface to be printed on is metal, pls check usage instructions as follows;

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

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

3. A base coat of grey or very light color is preferred, especial for uncoated reflective powder. .

Applying reflective bead paint on dark colors reduces the reflective effect by as much as 50%.

4. For good retro reflective, the reflective layer should be between 30-50um.

5. If the fastness is not well, little polyurethane can be put in.

6. Ideal mesh size for silk screen printing screens is 60-80 mesh. Smaller screen mesh size are okay as these create a thicker printed layer.

7. One kilogram of reflective powder can be mixed to produce up to 2 litres of reflective ink

8. One litre of ink can cover an area of about 6 square meters.

9. After painting, roll to roll press and dry 3 minute under150°C

Solution of getting strong retro reflective:

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

2. Firstly, print aluminum powder as foundation. Then print with the mixture of ink and reflective powder.

3. Make the reflective powder on the paint surface as more as possible.
