1. Flexo-based printing
North America, represented by the United States and Canada, is a typical example of the use of flexographic printing stickers. The equipment is a unit type printing unit, mainly based on ink water ink, and the spraying machine adopts round pressure round die cutting. The material processing method is web printing and web take-up.
2. About 50% of the printing methods for relief and flexo
This kind of processing method is represented by Europe, and the situation of flexographic printing labels is the same as that of the United States, but letterpress printing occupies a considerable proportion. All of the letterpress printing uses UV inks, and chvk-5g devices are mostly stacked or satellite. The material processing method is the same as roll paper printing and web take-up.
3. Toppan Printing
This processing method is represented by the Asia Pacific region. Most of the developing countries in the Asia-Pacific region are relatively backward in label printing. There are only a few equipments that use UV inks in letterpress printing. Most airless sprayers still use traditional resin inks for most labeling equipment. The material is processed in web form.
Now, we introduce the specific printing and processing technology of paper labels:
1, printing process flow
Different types of materials, labels for different purposes, the process used is also different. The general label printing press is a multi-functional device, and the processing plant can formulate the printing processing technology according to the customer's requirements. Adhesive label printing process flow is as follows:
(1) Unwinding
A. Intermittent: There is no tension change when the roll is unwound, so no adjustment is required. It is applied on the flat and round flat labeler, and the unwinding speed is slow. Due to the absence of paper positioning correction devices for such devices, it is required that the end face of the web be clean to ensure accurate overprinting during printing.
B. Continuous: Application in the round transformation round label machine. Since the tension of the paper changes when the diameter speed of the web changes, this device has tension automatic or manual control mechanism, high pressure airless sprayer, and web correction correcting device to ensure stable paper feeding and ensure printing quality.
(2) hot stamping
A. Flattening: It is used on round flat and flat labeling machines with low speed.
B. Round press circle: It is applied to the round press label printing machine. It has fast speed and can be used for continuous hot stamping. It is rarely used. Generally, the gold printing process is used instead of hot stamping.
