Structural color has attracted considerable scientific interest and industrial exploration in a wide range of technologies, such as next-generation display, healthy coating, chromaticity sensor, and anti-counterfeiting label. Printing as a facile way to pattern structural color is essential to achieve these advanced functions. In 2021, structural color printing made great breakthroughs in mechanisms, techniques, and functions. This article reviews the research hotspots and representative achievements in structural color printing including full-color printing with transparent ink, high-performance printing with colloidal photonic crystals, high-resolution printing with media materials, dynamic printing with responsive materials, etc.
