预变形技术在覆膜铁罐彩印中的应用

摘要

通过分析覆膜铁罐材料的各向异性对预变形技术的影响,及制罐用金属材料中的各向异性规律,探讨了彩印覆膜铁的图形设计变形规律,并在此基础上给出了彩印覆膜铁预变形图形的设计流程,实例分析证明了该方案的有效性。%Through analyzing the impacts of anisotropy of polymer-coated steel on the pre-distorted printing design and anisotropy patterns of metal materials in can-making, the rules of polymer-coated steel printing design distortion are explored and based on which the workflow of pre-distorted printing design is introduced. The results prove the project is feasible after tests and trials.
