Double-position Positioning Test and Analysis on Holographic/Protruding Lettering of Cigarette Packet Based on Machine Vision

摘要

In order to improve production quality and efficiency of cigarette trademark, new type reel cigarette trademark on soft package adopts production mode of reel to reel, which becomes the development trend. This technique makes higher requirements on double-position connection lettering and detection technology of holographic/concave and protruding lettering. This experiment uses on-line quality examination system to conduct the relevant examinations on double-position lettering of holographic/protruding lettering of cigarette packet and makes the analysis. The experiment shows that: holographic lettering quality varies with the amount of lettering and lettering speed. For protruding lettering unit, electrified aluminium in vertical direction has a better result than that in horizontal direction. This study lays a foundation for normal production of machine and further quality inspection after lettering.
