Lock-up is the final step before printing. The printer removes the cords that hold the type together, and turns the quoins with a key or lever to lock the entire complex of type, blocks, furniture, and chase (frame) into place. This creates the final forme, which the printer takes to the printing press. In a newspaper setting, each page needs a truck to be transported – 2 pages need 2 trucks hence the term "double truck". The first copy is proofed again for errors before starting the printing run.
