so far, eureka ebonite feed had conservative ink feeding amount.
this was to prevent over flow accidents, and achieve high stability.
previous attempts to increase ink flow while achieving high stability were full of repeated failures.
however, today i succeeded increasing ink flow by 40~50%, while achieving high stability.
from now on all eureka ebonite feeds are going to be set this way, allowing users to enjoy good ink flow (all the while achieving high stability of ink control)
