This project explored the limitations and possibilities of numerous user experiences—web, tablet, mobile devices and more. As a designer, finding suitable paper stock to present your design work is very important. There are also many printing materials in the world that we may not know about yet, so I came up with Materials Library, an app for finding material for printing. The main function of the app is to help users find a specific type of paper for their projects or to identify a paper material they are considering. The app also gives tips for suitable printing materials for a variety of designs.
