Originally launched in early 2012, “Paper” — developed by startup company FiftyThree — quickly claimed the mantle of Apple’s iPad App of the Year. Paper was a digital tool for creating and sharing sketches, diagrams and notes, but the app takes on an analog approach through a partnership with Moleskine. The two have come together to introduce Book, a new service that transfers your digital designs onto a custom-made hardcover notebook. Paper app users choose 15 pages of their sketches, which end up on the foldout pages of a Moleskine journal using FSC-certified matte paper. The print-on-demand publishing system was developed to match the iPad’s 4:3 aspect ratio, meaning there’s no need to re-size the images, and the user chooses which of his or her personal drawings will be used for the cover art. Priced at $40 and requiring a turnaround time of two weeks, users will receive a handcrafted book made with high-quality HP Indigo 4-color digital prints.
