China's printing needs of cigarette packets is mainly reflected in two aspects: First, cigarette packets field unit separation phase stability, color saturation; Second, cigarette packaging printing with high efficiency, low production costs. These needs are precisely the advantages of gravure printing, which is the main reason for the widespread application of gravure printing in the field of cigarette package printing.
New technology for cigarette gravure printing
Roll paper segment gravure printing technology
The technical process of the web segment gravure printing technology is: gravure printing → holographic positioning hot stamping → die cutting (with pressure bump) → finished product.
The web gravure technology is especially suitable for large-scale cigarette package printing, which can make the cigarette package printing enterprise obtain considerable economic benefits.
2. Multi-process integrated gravure printing technology
The R&D personnel who focus on the cigarette gravure printing technology have overcome the following three technical difficulties through many experiments, and finally realized the multi-process integrated gravure printing technology.
(1) Solving the problem of the standard seam of the common laser paper and the gravure overprinting of the web, and realizing the gravure printing of the web without the seam laser.
(2) By optimizing the process parameters of the pressure-concave roller and applying the anti-aliasing and over-pressure protection technology of the pressure-concave roller, the integrated production technology of the gravure printing and the embossing process is realized.
(3) By optimizing the gravure process parameters and improving the performance of gravure ink, the integrated production technology of gravure, offset and screen printing processes is realized.
