Embodiment Construction
[0041] The present invention will be further described below in conjunction with embodiment. The production process of this kind of sheet-fed offset printing reel color printing self-adhesive trademark mainly includes the following steps: surface paper sheet PS plate printing → edge trimming → sheet-fed printing surface paper is automatically glued into a roll → self-adhesive precision coating compound → Roll Die Slitting
[0042] 1. PS plate printing on surface paper sheet: ① Typesetting: according to the direction of automatic labeling of the roll, the trademarks are arranged equidistantly parallel to the bite edge, and the die-cutting tracking point and tracking line are marked on the edge of the bite edge and both sides of the drag gauge , Mark the trimming line on both sides of the pull gauge and side gauge. ②. The surface paper is treated with static electricity, temperature and humidity before printing to reduce the expansion and contraction of the paper. ③. When prin...
