By now anyone and everyone has most likely heard about LetterMpress. It has received almost double it’s goal in funding on Kickstarter, which I think is a good barometer for its high potential. I only wish it was going to be available on iPhones as well.
The app. itself will allow you to create custom letterpress compositions and prints in a user interface and process that parallels the real act of letterpress printing. You will also be able to print directly from the app. or export vector files of your designs for use in other applications such as AI.
