Crane's Lettra is engineered for letterpress. It is 100% cotton, soft and luxurious to the touch, yet strong and stable on press. Lettra's distinct "letterpress finish" is rare and engaging in a machine-made, commercial paper. Lettra is uncalendered, meaning that it is not smoothed in the calender stacks on the papermaking machine. The cotton fibers are relatively uncompacted, so the sheet feels extra-bulky, even fluffy. Cotton fibers are naturally long and strong, but also non-rigid. Lettra is made without surface sizing to maximize its suppleness and its receptiveness to a deep impression. It embosses beautifully. It debosses dramatically, foil stamps crisply and Lettra can be successfully offset-printed and engraved.
