   America's Favorite Greeting Cards

See How Greeting Cards are Made

Watch as flat sheets of blank paper are transformed into beautiful, full-color cards. You'll feel the roar of printing presses, each the size of a school bus, as they crank out two sheets per second. Follow the production process through precise cutting equipment, the rush of automated batching, and super-fast machines that fold 500,000 envelopes in one shift.
