Frequently Asked Questions

The name "Quoinlock" comes from traditional letterpress printing. In letterpress, a quoin (pronounced "coin") is an expandable wedge device used to lock type and printing blocks firmly in place within the chase—the metal frame that holds the printing form. Printers would tighten quoins to secure everything perfectly before printing, ensuring nothing shifted during the press run.

Just as quoins locked type in place to ensure consistent, accurate printing, Quoinlock helps you keep your book metadata locked in and monitored across the digital publishing landscape. We carry forward that tradition of precision and reliability from the age of hand-set type into the modern world of digital book distribution.
