Since the introduction of sticker printing technology from Japan in the early 1970s, China has gone through a 30-year process of sticker printing.
According to the different geographical areas, the types of ultimate customers, the application areas of the labels, the hardware configuration, the safety and security of the software, the label printing enterprises in China can be farewell to category 4 or It is called four levels, namely: low level, intermediate level, middle and high level, and high level. The difference is that each level has its own characteristics and has its own customer base. It is worth noting that the unevenness of the level of the printing plant and the economic benefits it obtains are not necessarily directly proportional, but depends on the market at different levels in various regions.
Low level
* Label product features
The label products processed by the low-end sticker label printing factory are characterized by a slightly larger format. They are usually mainly based on slightly outlined lines, pens, inks, and forms, with a small number of color mesh images and a small area on the ground. Its users do not have high requirements on the printing quality of label products, and there are no strict standards. Another feature of this type of label is the large number and single variety.
* Basic users
Therefore, if the ultimate user of the low-end sticker printing factory uses VIP (variable information printing) label-based industries, such as supermarkets, municipalities, electronics industry, warehouse hotels and daily chemical, pharmaceutical and other industries. As usual, these customers have to conduct secondary printing (or handwriting) on ​​the finished product labels, such as: the labels used in supermarkets, the product name and value must be marked on the electronic scale before labeling; the labels used in the city must use the price The gun prints the value on the surface of the label, and then pastes the label on the appearance of the product; the vacant label needs to use a barcode printer to randomly print product information, such as the production date and product serial number, during the production process. Other customers are companies that use slightly colored labels and do not have high requirements for label printing. Therefore, the structure of the low-level adhesive label products is slightly easier to process.
* Applied raw materials
Mainly based on matte paper materials, such as thermal paper, thermal transfer paper, matte paper with (without) coating and a small amount of coated paper, mirror coated paper. The film is mainly made of sub-silver PET raw materials, and a small amount of BOPP, PVC, etc.
* Printing configuration
This type of printing house is mostly based on letterpress printing, and a small amount of screen printing is granted (very few manufacturers grant flexographic printing methods). The ink used is mainly oxidized polymer offset printing ink, but a few manufacturers have used UV inks. , Or prepare to use UV ink. The configuration used is a label printer with flattening and round flattening, such as the configuration produced in early Japan (such as Iwasaki, Shiji, Onda, FSK, etc.), the Korean configuration that has entered our domestic land market in recent years, and from The configuration of Taiwan Province of China (such as Luotie, Wanjie, Yansheng, Shiluofa, etc.), and the large amount of localized similar configurations (such as similar configurations made by Taihang, Shijiazhuang and other printer factories).
Screen printing is mainly manual, mainly used for PET label printing. As usual, printing plants that mainly produce electronic labels are generally equipped with web-screen printing machines. In addition, the roll paper flat die cutting machine and small slitting machine are also necessary configurations for such manufacturers.
Intermediate level
* Label product features
In addition to the self-adhesive label products that low-level companies can process, intermediate-level printing plants can also process relatively large label products, including color prints that are mainly screen-printed, and such products are mainstream. product. Customers have inevitable requirements for the amount of products, such as: the hue of batch products, the accuracy of overprinting between color groups, and the same color density of batch products.
* Basic users
The basic users of this type of label are in the industries of medicine, public cosmetics and cosmetics, among which the label products of the pharmaceutical industry are its focus. Due to the characteristics of medical labels, it just fits the configuration methods and skill level of intermediate-level label printing factories. Another feature of mid-level label printing companies is that the types of customers are relatively large, and printed products include both short- and long-version products.
* Applied raw materials
In order to meet the requirements of the label structure, intermediate label printing enterprises should choose raw materials with good smoothness and high coating strength to adapt to the technical characteristics of color mesh coordinated field printing. Coated coated paper and mirror coated paper are the most commonly used raw materials, and a small amount of film raw materials (such as PE, PP, PET) are also commonly used by intermediate-level label customers. Intermediate label customers use a variety of raw materials, and the quantity is uncertain.
* Printing configuration
The key to distinguish the low-level printing water from Enron Anxiang Intermediate printing level is to look at the configuration means and level of the printing house.
In addition to the configuration of the low-level printing plants, the intermediate-level printing plants also have semi-rotary labeling machines, that is, round-and-circular relief printing machines for reciprocating paper feeding. The drying method of the ink is UV curing. At present, domestic manufacturers use the 300-type labeling machine produced by Tianjin Lindeco, and the similar configurations produced by Iwasaki, Sanjo and other configurations from Japan and Wan Ji and other manufacturers from Taiwan Province.
The characteristic of this kind of configuration is that it can be used for label printing in a variety of formats and batches. When changing the label variety, there is no need to change the printing cylinder. The paper size can be adjusted by adjusting the paper feeding step, and the adjustment and operation can be easily controlled. The disadvantage of this type of configuration is that the configuration itself has no dynamic tension control and overprint correction system, the paper feed path is too long and there is no paper guide wheel, so the raw material requirements are very high; the printing accuracy of the configuration is as ordinary as usual, in the plate making We need to cooperate. Therefore, this kind of configuration is suitable for printing as usual color halftone labels.
Intermediate level
* Label product features
Dominated by color labels, the label structure is relatively large. Processes such as online UV glazing, anodized aluminum rotary hot stamping, label adhesive appearance printing, and round die-cutting can be granted. Because there are many printing processing stations, one color can be printed in multiple stations, which greatly improves the quality of labels. Customers have strict requirements on the quality of label printing and processing, including the precise selection of raw materials, print hue, overprint and die cutting accuracy. Because of the high-level label processing technology, it is difficult for printing plants without similar configurations to process the same label products. In other words, the labels processed by these printing plants have the necessary anti-counterfeiting features.
* Basic users
Users are mainly in the mid-to-high-end cosmetics and lubricants industries, and also include a small number of customers who apply high-level labels in the daily chemical, pharmaceutical, and food industries. Such label products are as common as batch control, and order control is unchanged.
* Applied raw materials
Mainly based on high-grade paper raw materials, others are film raw materials. The paper materials include mirror coated paper and coated paper, and the film materials are mainly made of PE materials, and FasClear and Primax (Irley's patented products) are used in part. The raw materials used for these labels are all high-grade raw materials, because only good raw materials are used to print good products.
* Printing configuration
Mainly based on rotary printing configuration, such as Ko-pack, Sanky, Labelman in relief printing configuration, and multi-station narrow-width flexo printing machine, such as arsoma, nilpeter, comco, etc. The characteristics of this type of configuration are: high printing accuracy, high production efficiency, and large area printing. The full-rotary label printing machine has the raw material tension control and automatic deviation correction results, which can ensure the accuracy of label overprinting, so this type of configuration can print advanced label products.
Advanced level
At this level, there are only a limited number of self-adhesive label printing factories in China, and they are all foreign-funded enterprises. They have introduced the most advanced configuration, craftsmanship and wonderful skills in the world. This type of printing factory can process all kinds of advanced labels that are popular overseas, and the printing quality of the labels is no different from similar products in overseas countries.
