Color Connect

Platform: iOS

Roles: Algorithm development, chart design & production, iPhone app design, iOS programming

ColorConnect is an HP Labs research project that turns a smartphone camera into an inexpensive color measurement device. Working as part of a small 3-person team, I was responsible for developing the void-filling algorithm (patent pending) that enabled us to miniaturize the color chart into the size of a business card. As the lab expert in specialty printing, I was also responsible for chart production on our Indigo digital offset press, using a 7-color Indichrome (CMYKOVG) printing process. For the mobile component, I designed the color difference iPhone app for matching a print to a proof. Finally, I also dabbled in iOS programming and contributed the module that generated a custom PDF file based on the captured image. Overall, it was a very rewarding experience that allowed me to contribute in many different aspects.
