If you have a diaper that's meant for 8-12 hours of wear and intended to absorb multiple voids, just what is the purpose of a wetness indicator? If you have a need for such a diaper, you likely aren't going to be dry by then, and you won't be changing it after one wetting either..
I would think cost could be reduced by removing the ink and machine used for applying it too.
Thoughts? Comments? I don't see the purpose of it!
