This invention discloses a method and system for processing multi-layer thickness images in UV printing. The method includes acquiring the target thickness intention, outputting a three-dimensional joint instruction tensor of droplet volume, droplet temperature, and UV light intensity via a generative adversarial network (GAN), and then performing multi-physics collaborative printing based on this tensor. At the pixel level, the method independently controls the droplet temperature of each nozzle and the UV light intensity of each pixel, achieving differentiated modulation such as high stacking, tiling, and edge barrier walls. An error map is obtained by measuring the actual thickness in situ and calculating the expected thickness using a differentiable physical proxy model. This error map is then processed through a three-layer closed loop to achieve real-time correction, GAN update, and fine-tuning of the tactile mapping model. This invention significantly improves thickness control accuracy, substrate adaptability, and printing efficiency, and can be applied to various scenarios such as 3D relief, micro-optical components, functionally graded materials, and 4D self-folding.
