Printing process of three-dimensional anti-counterfeit package with local grating imitation function

The invention discloses a printing process of a local grating-imitating three-dimensional anti-counterfeit package. The printing process comprises the following steps: step 1, processing a pattern layer and an image-text area; step 2, high-fidelity color separation and mixed screening; step 3, UV gloss oil modification; step 4, plate making and printing; step 5, processing after printing; the high-fidelity color separation and mixed screening printing technology is adopted, the local grating-imitating three-dimensional effect of the package is achieved through color illusion and the printed material matte silver light pillar effect, the three-dimensional effect of the grating-imitating area is more highlighted through on-site white printing of the common image-text area, the anti-fake strength and decoration performance of the package are improved, and the packaging effect is improved. Meanwhile, the use of a grating plate is avoided, so that the environmental protection property of packaging is improved; acc
