Application and Solution of Label Narrow Rotary Printing (Part 2)

Second, solution introduction

After analyzing the above basic equipment configuration, we will discuss specific solutions. The total solution for label printing is divided into off-line mode and connection mode. The off-line solution is suitable for complex and varied short-run products. Because the number of products is small and the process is complicated, the off-line method can make the efficiency among different processes best. Play; connection solutions are suitable for medium and long version products, and the process is complex. Because the product technology is relatively stable, the connection method can maximize the production efficiency and product stability of assembly line operations.

In view of the higher quality printing of cosmetic labels and in-mold labels on the market today, we propose the following two typical printing solutions.

1. Flexographic printing-based solution

In the first printing station, we recommend the use of screen printing, hot stamping or cold stamping in the middle, followed by a set of screen or flexo printing units, and the final process is die cutting or winding. UV curing.

The advantage of this combination is that, under normal circumstances, most of the films for cosmetics labels are transparent. Therefore, the first color group adopts the screen printing method, and the opaque white ink is printed before the color images are printed, which can make the color images more vivid. For clarity; and, due to the flat opaque white, the reduction effect of graphic printing will be more prominent. Graphic printing uses flexographic printing. Hot stamping and cold stamping can increase the added value of the product; in the end, it can be applied by screen printing or flexographic printing units. Since this solution is aimed at film labels, cold UV can be used. Increase the cooling water roller of the servo drive to distribute the tension, and also consider the elimination of static electricity and die-cutting air suction device.

At the same time, this scheme can also increase the gravure printing unit. Under normal circumstances, gravure printing uses hot air drying; this configuration can also achieve some special metal ink printing.

This configuration can also basically meet the printing needs of in-mold labels. From the investment point of view, the total investment is small, suitable for small and medium enterprises.

2, glue-soft combination of solutions

This solution still uses rotary screen printing at the first printing station, followed by an offset printing unit that can be interchanged with flexographic printing, for printing color images; it can also be equipped with a group of gravure printing units for obtaining metallic inks. Special effects; followed by a set of screen printing units for glossing or special effects printing; followed by a set of flexographic glazing units; and finally equipped with the same die-cutting and rewind units.

The advantage of this program is that the offset printing cost is low, the dot printing effect is good, and it is more suitable for high-grade product printing; at the same time, due to the use of rotary screen printing to print the opaque white ink before offset printing, the printing effect of offset printing is guaranteed, and in After adding a gravure printing unit, the integrity of the process is further enriched. In this program, it can also be equipped with hot stamping, cold stamping and other processes. One of its more prominent features is that these process units can all be interchanged to achieve maximum process flexibility.

The program can meet almost all process needs, and can adjust the process at any time according to the changing market, with a very strong market competitiveness. However, its investment scale is also relatively large, and it is suitable for some large-scale label printing companies.

From the above program combination, we can see that narrow-width rotary printing equipment has distinctive technical characteristics—flexible, high-efficiency, high-quality, and low-cost. These characteristics precisely fit the needs of the current domestic label market development. In developed countries, narrow-web rotation printing accounts for more than 70% of the entire printing market. However, in China, the current share is only about 7%, and the market has very large room for development. Simultaneously. We are also delighted to see that a group of top-tier suppliers of narrow-width rotary printing equipment have entered China and set up offices and training centers in China. Relevant material suppliers or consumable suppliers have also responded, and it can be predicted that in the near future, narrow-web printing will set off a wave of innovation and progress in China.
