Relief printing vs flexographic printing

I believe that everyone in the industry engaged in label production or equipment sales has considered and discussed with others the question of who will dominate the embossing and flexographic printing in China's label market a few years later, and everyone knows that the European and American market is the world of flexographic printing, while the embossing printing in the Japanese market accounts for almost 70% of the market share. So, what kind of pattern will China's label market be in the future

personally, the development of the Chinese market is not a simple replica of the European and American markets, nor will it be a simple replica of the Japanese market. Instead, it will take just a few years to develop rapidly driven by the internal force of the market, so as to go through the exploration road of the European, American and Japanese markets for decades. The final pattern will be the coexistence of embossing and flexo printing for a long time, the market share of flexo printing will continue to increase, and seize the profits of the entire upper half of the gold tower in this field. Embossing will take advantage of its own printing characteristics and cost characteristics, and will exist for a long time in the small batch of simple movable parts printing

why is there such a judgment

everyone knows that flexographic printing is the mainstream in the European and American label market, but in fact, in the late 1980s, embossing accounted for almost 80% of the market share in the European and American market. Why do Europeans and Americans have to turn embossing into flexo printing? Is it simply because flexo printing is more environmentally friendly than embossing? The real reason is far more than this

compared with relief printing, flexographic printing has the following advantages:

1 Fast printing speed

generally, the normal printing speed of flexo can reach more than 100m/min, but the speed of rotary convex printing machine is generally 30m/min~50m/min, that is to say, the efficiency of one flexo printing machine is almost equal to that of two or even three rotary convex printing machines. More importantly, the current flexographic printing machine is equipped with many post press processing devices at the same time, which can realize rapid indentation, bronzing and die cutting (including roll to roll, roll to sheet), and realize one-stop processing and molding, which can effectively guarantee the delivery of product labels of mature brands in a timely manner

2. More suitable for standardization

flexographic printing machine has an obvious advantage over embossing machine, that is, it is more suitable for standardization. Industrial products need standardization. The label products of previous and subsequent batches are required to be made according to the unified color standard. And label products usually need a lot of spot colors, which are quite sensitive to color difference. The rotary embossing machine adjusts the printing color difference by controlling the ink flow and printing pressure in the ink bucket, and it is very unstable in the printing process, and often needs to rely on the experience of operators to adjust it immediately. Flexographic printing machine adjusts the ink amount by changing the corrugated roller. Once the appropriate corrugated roller is selected, the color difference changes little in the printing process, which can reduce the basis for the operator's experience to a certain extent. This is very important for the labels of mature consumer products. Customers do not want their product labels to have a deep and shallow phenomenon in the market

3. More uniform performance in spot color

the performance standard of standard anchoring agent mentioned above mt143.1 ⑵ 011 label printing often uses spot color, especially in large areas of the field. When the rotary embossing machine prints on a large area, it is easy to have uneven ink layer and even whitening. However, this phenomenon can hardly be seen in Flexo label products. This is also determined by the two ink transfer methods of printing mentioned above

4. Flexographic label products are brighter and more saturated

the color and saturation of roto embossed products are generally not as good as flexographic label products. This is determined by the composition of the two inks. Labels printed by rotary convex printing machines that need to be printed with poor thermal stability light ink, after being transferred to flexographic printing machines, often do not need to be polished to achieve the gloss required by customers. Transparent labels are often used in daily chemical products. The transparent labels printed by rotary embossing machine are dim even if they are varnished after printing, especially on the patterns with white background, but they can be bright and saturated when printed on flexographic printing machine

5. Flexographic printing machine is easier to realize the need of combined printing

now many exquisite labels, especially those on daily chemical products, often use combined printing, usually a combination of several printing processes. Compared with rotary relief printing, the unit type narrow flexographic machine is easy to achieve this requirement, which can be flexo + silk screen printing, flexo + lithography, flexo + gravure, or even a combination of more than three printing processes based on flexo printing. Personally, I think this is a direction for the printing requirements of high-end label products

6. Compared with embossing, flexo printing is more environmentally friendly

both UV ink and flexo ink are quite environmentally friendly. The ink is non-toxic and tasteless, which meets the health requirements of FDA. Nowadays, many multinational companies require flexographic printing to replace embossing in the outer packaging of drugs and food. Now the packaging of food and pharmaceutical products has become the main customer source of flexo printing

in previous years, the development speed of flexo printing in China was largely limited by its immature technology. The plate making cycle is long, the cost is high, and the technical level of operators is generally not high. With the increasing proportion of plastic packaging in the packaging industry, printing quality is not ideal, and the large consumption rate of short version makes many entrepreneurs who pay attention to flexography flinch. However, with the rapid development of technology, many of these problems have been solved, and more and more high-quality printing is presented to you through the combined solutions of flexography, More and more professional flexographic plate manufacturers can provide printing houses with plate making services of good quality and low price in a very short time. It can be said that the practical experience of European and American countries in these years has paved the way for the popularization of the Chinese market tomorrow. This is one of the reasons why China will go through more than ten years of development in the European and American markets in a few years

I'm afraid all the printing factory bosses' favorite jobs are long edition jobs that remain unchanged throughout the year and are large and uniform, but after all, not everyone has such good luck to always receive such jobs. There are more and more jobs with small quantity, high quality requirements and short delivery time requirements. Of course, the unit price of such jobs with a large market share in China is often relatively high, but it is difficult to meet the requirements of customers with ordinary relief self-adhesive machines. Using ordinary flexographic machines often wastes a lot of paper and time, and the final printing quality may not meet the requirements of customers. Therefore, If there is a machine that can meet various printing and processing requirements such as flexographic printing, embossing printing, silk screen printing, gravure printing and even offset printing at the same time with low cost and high quality on one line, the most important thing is that the preparation time for the change of live parts should be short, the machine can be adjusted quickly and the waste of materials should be less. Then, this kind of machine must be the one that can bring maximum benefits to users

as we all know, the best profit period of any industry is in the first few years. People often hear people complain about themselves: "late!". Nowadays, China's flexographic printing industry has brought such an opportunity to manufacturers. Perhaps the flexographic machine may not be able to see huge returns immediately, but the people who earn the gold spire in this market a few years later must be the people who start to act now
