Every copy pays the press its creator share of the tax in BNB, after Flap's fee and its typist's commission, each time its tax is dispatched.
Every copy pays the press
Anyone can retype any title, as often as they like, and no copy earns from the copies typed from it: every copy pays the press, and only the press pays the writers.
Four carbons
A copy carries four one-time codes, each typing one new copy from it, a generation fainter, until the fourth generation, whose carbon is spent.
Generations fade
Each generation prints a shade fainter, as carbon copies do, and the title itself is always open for a fresh first copy.
Per sheet, not per copy
A title's sheets become payable at the fee in force when it was published, 7 days after the later of its publication and its pen name's seating, while the pen name has at least five members; nothing is paid per copy.
