About ink Induction (capillary phenomenon)

The ink of the marking is drawn out by using the principle that the ink is pulls to the narrow one of the gap even if power is not added from the outside. A rough flow is the form of batting (relay core) → nib → writing surface.
The capillary phenomenon is due to the effect of the wet force of the liquid. The ink goes up even if it is upward because it is power to go up against gravity.
