The development of special printing

the so-called special printing is relative to the general printing. Before the 1970s, the popular printing method in Taiwan was letterpress and flat, which was generally called a printing factory or printing shop at that time; Self adhesive label printing appeared in the second half of the 1970s. At that time, the market demand was very small, and the printing equipment, technology and process used were completely different from general printing. Therefore, the printing industry called it special printing. In fact, the so-called special printing is not limited to self-adhesive label printing. I personally believe that as long as I can innovate in various printing methods, what is different from the general printing technology belongs to special printing. This paper only observes the development trend of special printing from the perspective of self-adhesive label printing according to the general habit

features of self-adhesive label printing:

1 Multiple processing functions, such as printing, laminating, bronzing, chopping, slitting, sheet cutting, edge paper stripping and many other processes can be completed at one time

2. The automatic labeling machine can be used to quickly paste the label when the paper is rolled out or rolled in

3. There are many kinds of available materials, such as a variety of paper, a variety of plastic films, aluminum foil, cloth, etc

4. There are many printing methods. Relief, lithography, plate, flexo and intaglio can be used for self-adhesive label printing. The recent development trend is to combine multiple printing methods to print at one time, and show the characteristics of multiple printing methods on one label

the self-adhesive label printing factory has more or less the above features. Therefore, most of the manufacturing processes are self-made in the factory and do not need to be outsourced. Unlike the general printing factory, it needs a complete third-party manufacturer to complete the printing one by one. In general, the self-adhesive label printing factory has small order quantities, diverse demands and large changes. If there are too many outsourcing jobs, it will not be able to flexibly meet the needs of the market. In addition, the self-adhesive label printing plant is basically a printing industry. If the technology required by the printing industry is not well understood, or the process management is not sound (such as color separation and plate making), it is easy to become a simple processing plant

changes in market demand

before 1970, non film label (lithographic printing) accounted for 70% of the total volume label consumption. By 2000, non film label decreased to 33%; In 1970, the self-adhesive label, which was just emerging, accounted for only 5%, and in 2000, its share grew to 58%. Others, such as Kraft rubber label, heat sealing label and other labels, accounted for 25% in 1970 and about 9% in 2000. Among them, the share of self-adhesive label has grown from 5% to 58%. Technological progress and improvement of machinery and equipment are one of the main reasons, but the most important factor is the change of market demand

with the popularization and development of computers, printing volume labels with printers came into being. For example, price volume label, bar code volume label, variable data volume label, letter delivery volume label, transportation volume label, etc. And its use is amazing. These volume labels are not self-adhesive and cannot be replaced by other volume labels

in the past 20 to 30 years, people's lifestyle has changed greatly, the types and shapes of commodities have changed, and the business path has also changed. The traditional market has given way to supermarkets, and grocery stores have been replaced by convenience stores. Salesperson selling becomes shelf selling. The most important thing in the kitchen is the refrigerator. The refrigerator weighs two kilograms, and then the packaging becomes bottles, cans, boxes and frozen packaging. All of them need self-adhesive labels. Moreover, the bottles, cans and boxes placed on the shelves without speaking must rely on the trademarks affixed to attract customers' attention. Due to these changes in lifestyle, the demand for self-adhesive labels has been more diversified

in a society that pursues innovation and continuous improvement, the life span of commodities is continuously shortened. Continuous introduction of new products is the means of sustainable operation of enterprises. The introduction of new products must attract attention and stimulate consumers' desire to buy. Whether to extend the life of old products or promote new products, a large number of promotional labels are required. In addition, old brands and high-value goods with good quality and reliability are often imitated by unscrupulous manufacturers to obtain improper interests and damage the goodwill of the original manufacturers. In order to protect their own goods, various anti-counterfeiting labels are popular in the market. The increase in the demand for promotional labels and anti-counterfeiting labels has contributed to the increase in the market share of self-adhesive labels

with the sharp increase in the market demand for volume labels, the growth of material types, material processing and printing technology has also accelerated. In addition to the original label types, new label types have also emerged. For example, flexible adhesive film label, shrink film label, in mold label, reel label (such as Coca Cola bottle), hose material printing, etc. have continued to grow in the past 10 years, expanding the scope of self-adhesive label printing to the field of packaging material printing

containers made of pet, PE, PP and other plastic materials, such as bottles, cups and boxes, have a significant impact on label printing; Because of the change of living habits, people gradually need portable plastic containers to package food, beverage, detergent, oil and medicine. Plastic containers are light, thin, low-cost and large-scale, which soon replaced glass containers and became the mainstream of packaging containers; In the era of extensive use of glass containers, self-adhesive label has not been fully used, and the cost is relatively high; At that time, most of the labels used non adhesive labels and water glue. In the era of plastic containers, wiping water glue on plastic containers is not easy to stick firmly and flat, and it must wait for drying time. On the contrary, the self-adhesive label does not have these shortcomings. With the development of high-speed automatic labeling machine, the adhesive speed is fast. Soon, almost all the commodities using plastic containers were self-adhesive labels

plastic containers not only promote the use of self-adhesive label, but also promote the vigorous development of flexible film label, shrink film label, in mold label and reel label. In addition, the in mold label and reel label have been growing at a double-digit annual growth rate in recent years due to the demand trend

in the past, the tubes of toothpaste and cosmetics were blown one by one after forming, and then the upper lines were printed by curved surface printing. Now, due to the emergence of plastic laminating materials, reel materials have been used to form hoses after rotary printing. This method is convenient and fast, so it has a certain market demand

volume labels are not only used more in the market, but also used more and more. The industry is constantly trying to produce different types of volume labels, so the whole industry shows a high growth rate. Over the past three decades, the growth rate has fluctuated between 3% and 7%; It is 2% higher than the growth rate of GDP, and the growth rate of self-adhesive label is about 4%. The growth rate varies significantly depending on the type of label. Some show double-digit growth, while others show negative growth. Everything depends on the needs of the market. If you meet the needs, you will grow. If you do not meet the needs, you will not grow. The label industry seems to be very sensitive to market demand

with the expansion of market demand, label printing machines and equipment are becoming larger and faster. Like ordinary printing, it is impossible to avoid fierce competition in price. But on the contrary, the form of shelf selling requires that the quality of the label become more and more advanced and the color become more and more abundant. Therefore, it promotes the application of lithographic rotary machine in label printing, and also promotes the rapid development of flexographic printing technology. At present, the printing quality of flexographic printing is no less than that of lithographic printing, and even more unique. At the same time, it has promoted the prevalence of composite printing presses in recent years. In the face of changes in market demand, the self-adhesive label factory has to tend to a large-scale business model, regardless of its pursuit of unique shell materials for the French wing in terms of output and quality

ten years ago, the surface printing adaptability of plastic film was poor. Most self-adhesive labels used paper. The paper has low price, good ink absorption and fast drying, which is suitable for mass printing. However, due to good ink absorption, the printing surface can not obtain a bright printing effect, and can not meet the high-quality requirements of self-adhesive label. The improvement of the printability of the plastic film surface and the development of UV drying technology have gradually made the label printed with plastic. The trend of non paper label is gradually formed. At present, the growth rate of paper is about 5%, while that of plastic film materials is 15%

another factor that affects the excellent performance of plastic label should be noted that the higher temperature is the rising awareness of environmental protection in society. We mentioned that the prevalence of plastic bottles, cups and boxes has contributed most to the growth rate of volume labels. However, people pay more and more attention to the pollution of the earth. Used plastic containers must be able to be recycled. Used plastic containers can be crushed, dissolved and reused. If the labels on the containers are heterogeneous paper labels, recycling will be troubled. Therefore, the label must be made of the same material as the container. PET bottles should use PET film, PE bottles should use PE film, and PP bottles should use PP film. This requirement has also contributed to the growth of plastic labels

the customer is the king, and the goods must meet the consumers' preferences. Recently, consumers have further improved their demand for alternative manufacturing technology and overall strength, that is, the container and label must be integrated, or the contents (liquid) can be seen through the label and container. In other words, they do not like that the label is pasted or covers the contents (liquid). The so-called no label look. Therefore, the in mold label and ultra transparent label have been developed. The in mold label is cut after printing. One label after another is put into the mold with a robot arm, and then the hot-melt plastic is poured into the mold. The back of the in mold label is dissolved with its heat, and attached to the formed container to form a smooth integration with the container, In this way, the thickness of the test object is not protruded according to the requirements of the national standard gb/t17761 (1) 999 "test method for strength of cement mortar". Now, bottle blowing, injection and molding can be combined with this production method, and it is a popular label type. The material of the ultra transparent label is completely transparent, which is pasted on the transparent bottle. The contents (liquid) in the bottle can be seen at a glance through the bottle and label; These production methods make use of the particularity of bottles and labels to increase the sense of value of goods and attract consumers' desire to buy

the demand for self-adhesive labels has always been the most developed in Europe and the United States, especially in Western European countries, which pay the most attention to labels and compete to improve the sense of value of goods with the quality of labels. In 1998, the demand for major labels in Western European countries accounted for 30% of the world's demand, but the forecast shows that due to the economic development of Asia, the demand for labels in Western Europe may fall to 26.6% of the world's share by 2005; The industry believes that the demand for volume labels in Asia will continue to grow. From 1989 to 1996, the growth rate of label demand in advanced countries was 6.7%, while it was as high as 12.8% in Asia during this period. It is estimated that the growth rate may increase in the future. In fact, the world's famous material factories and machine factories have come to Asia to sell more and more frequently
