(Update09) Thermochromic Ink

Nov 13
The thermochromic Ink arrived finally and Andre brought me to his shop. We tried both overlay and mix up the 3 colours and these two means both works. How ever the activation temperature remains to be verified.
    1. The Matrix Pattern
     2. Mixing up the 3 types of thermochromic inks ( red->17c     blue -> 31c    green -> 47c)
     3. Andre is doing screen printing
       4. the printed Tshirt
     5. After applying the ice bag on the color changing module, the temperature decreases and red appear
    6. the temperature increase to room temperature, blue comes out
   7. use hair dryer to blow the patten, blue disappear and green come out, and becoming transparent.
