The development of labeling equipment does not advance the technological progress of adhesive label printing

With the development of the times and the advancement of science, the emergence of new processes and new equipment in the label industry has revolutionized the label printing technology, improved the production efficiency, and ensured the printing quality. In the following, based on my personal understanding, the connection between "the development of label equipment and the technical progress of sticker printing" is elaborated from several aspects.

The emergence of reciprocating paper-feeding UV letterpress equipment is a revolution in sticker printing technology

Ten years ago, more than 90% of the equipment in China's sticker printing industry was flat and round flattened label machines. Some of these devices were introduced in Japan, such as FSK's B-100 series flattening label machines. Entian company's 250, Iwasaki's Shiky series; the other part of the same type of equipment for domestic production, such as Shijiazhuang Printing Factory flat pressure 180, Taihang Printing Factory round flat labeling machine. The other type of equipment is Japan's Ko-Pack and Sanky full-rotation UV letterpress equipment. Since such equipment is expensive, all imported, and generally small and medium-sized enterprises do not have the ability to import, so this kind of equipment is very few in China, only some foreign-related printing. The factory is equipped with a small number of such machines.

The printing quality and printing efficiency of the flattening and round-flattening labeling equipment are all restricted, so ten years ago, the label printing was still dominated by lines, blocks, and texts, and it was difficult to print high-end and beautiful half on such equipment. Hue color prints come.

The emergence of reciprocating feeders has fundamentally changed the adhesive printing technology. Several aspects have identified the advantages of this type of equipment in the Chinese label industry:

1) In the principle of printing, like the traditional flat and round flat label machines, all belong to relief printing. In the printing process and the plate making process, the original technology can be fully applied to new machines. No changes are needed, and all of them can be transplanted and used without new investment and investment.

2) Since this kind of equipment does not need to replace the plate cylinder within a certain range, it is theoretically possible to print various types of labels of different sizes, to realize the versatility of one machine, which greatly facilitates the operation and improves the working efficiency.

3) Reciprocating paper feeders can print both long-run and short-run prints, as well as print complicated prints and print simple prints. In terms of printing quality, it can be compared with a full-rotation device. Due to the rigid lining of the impression cylinder of the device, the dots are printed with small deformation and beautiful color, even exceeding the satellite rotary labeler.

4) At the equipment price, the reciprocating feeder is about half of the satellite full-rotation equipment. Generally, customers who have accumulated for a period of time are fully qualified to purchase.

If we say that the label industry was dominated by flat and round flattening equipment ten years ago, then the label industry in the future will be a device layout based on reciprocating feeders. Now, it is not uncommon for a printing plant to have several reciprocating feeders. Some plants even have four or more similar equipment. Some label factories have purchased full-rotation satellite labelling machines or flexographic plates. Still purchasing reciprocating feeders. The trend of development in the future is that a label factory cannot adapt to the needs of production without a reciprocating paper feeder, and it cannot participate in the market competition of label printing.

The development of the label industry in northern China has fully proved this point of view. Taking the development of Xi'an and Shijiazhuang regions as an example, the number of reciprocating feeders in these two regions has increased rapidly in recent years. Both of these regions are professional label factories mainly engaged in the printing of medical labels. Several years ago, they were completely sheet-fed offset printing and simple flat and circular press-flat printing. Due to the lack of comparability between printing quality and printing efficiency at the time, the competition was not intense. However, as long as one of them purchases a reciprocating feeder, other households follow suit. Because they do not advance, they will withdraw. Whose equipment is good and the quality of the printing is good. Whoever becomes the best choice for a pharmaceutical factory. Therefore, the market demand is the root cause of the rapid development of label printing in these two regions and the progress of printing technology.

PS version label printing equipment makes label printing easier and faster, with better quality

Offset printing is the most commonly used traditional process in the printing industry. It is a single-sheet printing in sticker printing. It is applied to the self-adhesive printing equipment for roll-type paper feeding, and is still a new attempt in recent years.

Roll-type printing labels were originally used on combination printers, such as the Nilpeter-MO series, Gallus-Arsoma, etc., only as a combination. Afterwards, offset-type reciprocating paper-feeding rotary labellers also entered the market, such as Japan's Sanky, Iwasaki, and similar domestic equipment of the most recent domestic brands - Donghai, Zhongtian, Taihang, and Yutian Printing Machinery.

Rolled offset printing labels can compensate for the lack of flexo and embossing on the reproduction of the gradation, making it easier for prints of long-graded prints to be reproduced. When the label printers are printing on the letterpress, the problem often encountered is that the film is repeatedly modified. Otherwise, the printed materials are lost on the small outlets and the large outlets are crushed. This is because the discs received by the salesperson are offset printing layouts, or the computer company installs offset printing. Standard color separation. The printing plant must combine the actual conditions of its own embossing equipment, redragate the calibration, color separation, and determine the minimum and maximum printable dots.
