As someone mentioned few pages back, if you have multiple stacks of 11 ink (and scrolls if you plan on making more than 19 per DC) in your inventory you can make multiple cards per DC. When crafting, it uses the materials closest to the top of your inventory. So you start with multiple stacks of 11 ink all lined up, and once each stack of 11 is used, you move the 1 remaining ink further down in your bag below your other stacks of 11 ink. Rinse and repeat. Same goes for scrolls, except you can make up to 19 cards before having to shuffle your scrolls.
Probably did a poor job explaining, Lives did a better job here:
