Plasmonic colour printing has drawn wide attention as a promising candidate for the next-generation colour-printing technology. However, an efficient approach to realize full colour and scalable fabrication is still lacking, which prevents plasmonic colour printing from practical applications. Here we present a scalable and full-colour plasmonic printing approach by combining conjugate twin-phase modulation with a plasmonic broadband absorber. More importantly, our approach also demonstrates controllable chromotropic capability, that is, the ability of reversible colour transformations. This chromotropic capability affords enormous potentials in building functionalized prints for anticounterfeiting, special label, and high-density data encryption storage. With such excellent performances in functional colour applications, this colour-printing approach could pave the way for plasmonic colour printing in real-world commercial utilization.
表面等离子体激元彩色印刷作为下一代彩色印刷技术的一个有前途的候选者，已引起广泛关注。然而，仍缺乏一种实现全彩色和可扩展制造的有效方法，这使得表面等离子体激元彩色印刷无法实际应用。在此，我们通过将共轭双相调制与表面等离子体激元宽带吸收器相结合，提出了一种可扩展的全彩色表面等离子体激元印刷方法。更重要的是，我们的方法还展示了可控的变色能力，即可逆颜色转换的能力。这种变色能力在构建用于防伪、特殊标签和高密度数据加密存储的功能化印刷品方面具有巨大潜力。凭借在功能性彩色应用中的如此优异性能，这种彩色印刷方法可为表面等离子体激元彩色印刷在实际商业应用中铺平道路。
