Print industry is one of the backbone industries in China, however, it produces huge amount of solid wastes, air emissions and wastewater. Based on the manufacturing of functional nanomaterials and controllable spreading and transferring of liquid droplets, they fabricated the superoleophilic patterns on the hierarchically structured superhydrophilic plate by ink-jet printing. Thus the image area and non-image area can be generated on the plate, which can be directly used as the printing-plate. It abandons the photosensitising process, and thus the new technology discharges no chemical pollutants, simplifies greatly the operation process, and lowered substantially the cost. Moreover, they employed the green printing technology in printed electronics based on metal nanoparticle ink, which simplifies the complicated preparation process of traditional photolithography method, and significantly prevents discharge of chemical pollutant. Nanomaterial green printing technology will lead the printing industry into a new age of greenization and digitalization.
