[7/11 上午8:09] Ryan Sun (来宾) Hi, Bellie, I think FT-02 is also a good way as a evaluation method, however, i do not think it should replace the GE-29 directly. Because, FT-02 is more a static test to simulate the color migration when contact with other media, but GE-29 is more a dynamic test to simulate abrasion situation (the APC case is happened when they use white paper or hand to rub on the inner box, then the color migration happened), so for my suggestion, i prefer to keep both for safe side.
