摘　　要：传统印刷技术的视觉效果单一,且普遍使用重污染的重金属和高分子材料的油墨,造成了严重的环境污染。为解决上述问题,本研究探索了一种基于折衍混合结构的无油墨印刷技术。通过微纳结构对光学折射和衍射现象实现了彩色化,并利用莫尔成像原理突破了传统印刷中难以实现三维和动态视觉效果的瓶颈,提供了丰富的视觉效果。采用激光直写和干涉光刻制版,结合压印技术制备的基于微透镜阵列和光栅结构的印刷品,具有高分辨率、低成本和环境友好的优点。本研究所提出的无油墨印刷技术满足了人们对印刷品质的不断追求,具有巨大的应用潜力。Traditional printing technology offers limited visual effects and typically relies on inks containing highly polluting heavy metals and polymers,resulting in serious environmental pollution.To deal with the above problems,a hybrid refractive-diffractive and ink-free printing technique was explored.Vibrant colorization was achieved using micro-nano structures to control light refraction and diffraction.Furthermore,the moiréimaging principle was used to address the challenges of creating three-dimensional and dynamic visual effects in conventional printing.Through a combination of laser direct-writing lithography,interference lithography for mold fabrication,and large-scale nanoimprinting lithographic techniques,printed materials incorporating microlens array and grating were produced,which have the advantages of high resolution,low cost,and environmental sustainability.This ink-free printing technology not only offers rich visual effects to meet the growing demand for high-quality printing but also holds significant potential for widespread application.
