This cover story on the state-of-the-art of the smart phone industry needed an appropriately high-tech design to reflect the futuristic slate of the article. My source patterns were from a stock image CD by Simon Osborne/Digital Visions, and the cover was built up with several dozen layers in Photoshop. Unique to this cover -- and not readily apparent in the RGB image here, -- was that I had the printing plant substitute metallic inks for the cyan and magenta plates, which gave the cover a very bold and vibrant look. It was a little risky, as I couldn't see a proof that could accurately simulate these special inks, but I was very pleased with how the final printed piece came out!
