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

Abstract

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.

Online synchronous inspection and system optimization of flexible food packaging bags by using machine vision and sensing technique

“…A so-called pattern-difference norm is utilized for checking the qualification of the package.   − prs pr P P (3) where Ppr means the real pattern of the item in inspection, which may be expressed in matrix. Then, Pprs means the ideal or standard pattern of item used as the reference in matrix.…”

“…Wang et al [2] worked out a theoretical integration system of the technological transformation of enterprises and products for new packaging production. Xing et al [3] developed a reel-to-reel model for the improvement of product quality and efficiency of cigarettes by higher requirements with soft package trademark on holographic/concave as well as protruding lettering. To increase the quality and safety of the transparency of the products, Schneider and Franke [4] carried out a 100% inspection with process control of the whole production line, providing the framework for the total analysis through correction and refinement of the feedback variables.…”

Study on Aluminium Coating Process of Holographic Anti-Counterfeiting Cigarette Packet

“…Hongtashan (Classic 100) cigarette packet is a paper-based holographic packaging material [1,2], which uses PET as the main imaging substrate; after the moulding process and the aluminium coating process, the imaging substrate would bear a information layer needed; then transfer the information layer to paper, thus forming the packaging material required. Holographic anti-counterfeiting packaging materials can exhibit a variety of effects, such as dual-channel, gray scale, micro text, invisible watermark, the flash effect and so on [3]. To resolve the color difference problem between samples and proofs in Hongtashan's proofing process, parameters of the aluminium coating process is analysed.…”
