Judgment of Label Printing vs. Flexo Printing

I believe that everyone in the industry engaged in label production or equipment sales has thought about and discussed with others who will dominate the embossing and flexo printing in the Chinese label market a few years later, and everyone knows that the European and American markets are the world of flexo printing. Relief on the Japanese market accounts for almost 70% of the market share. So, what kind of pattern will China's future label market have?

I personally believe that the development of the Chinese market is neither a simple copy of the European and American markets nor the Japanese market. Instead, it will take only a few years to develop rapidly with market internal forces as the driving force, thus passing through the European, American and Japanese markets for decades. On the way of exploration, the final pattern will be the long-term coexistence of relief printing and flexo printing. The market share of flexo printing continues to increase and seize the profits of the entire first half of the Golden Tower in this field. Relief printing will use its own printing characteristics and cost characteristics for a long time in simple small-batch printing of very small batches.

Why is there such a judgment?

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

Compared with letterpress printing, flexographic printing has the following advantages:

1. Fast printing speed

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

2. More suitable for standardization

The flexographic printing machine has an obvious advantage over the relief printing machine, that is, it is more suitable for standardization. Industrial products need to be standardized. The label products of the front and back batches are required to be able to be produced with a uniform color standard. Moreover, label products usually require many spot colors, and their sensitivity to color difference is quite strong. The rotary embossing machine adjusts the printing chromatic aberration by controlling the flow of ink in the ink fountain and the printing pressure, and is very unstable during the printing process, often relying on the experience of the operator to adjust it in real time. Flexographic printing machine printing adjusts the amount of ink by changing the anilox roller. Once the appropriate anilox roller is selected, the color difference during printing is very small, which can reduce the basis of the operator's experience to a certain extent. This is very important for the labeling of mature consumer products. Customers do not want their product labels to appear in the market.

3. More uniform performance in spot colors

As mentioned earlier, spot printing often uses spot colors, especially on large areas. Rotary relief printing machine printing on a large area, it is easy to appear uneven ink layer, or even the phenomenon of whitening. However, this phenomenon is hardly seen in flexo printed label products. This is also determined by the two ink transfer methods mentioned above.

4. Flexo label products are more vivid and saturated:

The color and saturation of roto-relief products are generally inferior to those of flexo labels. This is determined by the composition of the two inks. Labels printed by roto-relief printing machines that require glazing inks are transferred to flexo printing machines for printing, and often do not require glazing to achieve the gloss required by customers. Day-to-day products often use transparent labels. The transparent labels printed by the rotary embossing machine are dim even if they are varnished after printing. This is especially true of patterns with a white background, but printing on a flexographic printing machine Very bright and saturated.

5. Flexo printing machine is easier to meet the needs of combined printing

Nowadays, many exquisite labels, especially the labels on daily chemical products, often use combination printing, which is usually a combination of several printing processes. Relative to rotary letterpress printing, unit-type narrow-width flexo printing machine is easy to achieve this requirement, it can be flexo + silk screen, or flexo + lithography, or flexo + gravure, or even flexo-based, three More than one combination of printing processes. I personally think that this is a direction of printing requirements for high-end label products.

6. Relative flexo printing is more environmentally friendly

Regardless of whether the flexo printing uses UV ink or flexo printing ink, it is quite environmentally friendly. The ink is non-toxic and odorless and meets the FDA's hygiene requirements. Nowadays, many multinational companies require the use of flexo printing instead of embossing for the outer packaging of medicines and food. Now the packaging of food and pharmaceutical products has become the main source of customers for flexo printing. In the past few years, the development speed of flexo printing in China is largely limited by its immature technology. The long plate making cycle, high cost, the general technical level of the operator is not high, the printing quality is not ideal, the short live loss rate and other issues make many entrepreneurs concerned about flexo plate prohibitive, but today, with the rapid development of technology, these problems It has been solved, more and more high-quality printing is presented to everyone through the combined solution of flexo printing, and more and more professional flexographic plate-making manufacturers can provide printing companies with good quality and low-cost plate-making services in a short time. . It can be said that the practical experience of the European and American countries over the years has paved the way for the popularization of the Chinese market tomorrow. This is one of the reasons why China will go through the development road of the European and American markets in a few years.

The favorite work of all printing plant bosses is probably a long version of the work that is constant throughout the year and the amount is very large, but after all, not everyone has such good luck to always receive such work. The quantity is not large, the quality requirements are high, and the short delivery time requires more and more jobs. Of course, the unit price of such jobs is often relatively high, but it is difficult to meet the customer's requirements with a general letterpress adhesive machine. General flexo machines often waste a lot of paper and time, and the final printing quality may not meet customer requirements. Therefore, if there is a machine that can meet flexo and embossing at a low cost and high quality on a line , Silk screen, gravure printing and even offset printing and other printing requirements and processing requirements, the most important thing is that the preparation time when the live parts change is short, the machine adjusts quickly, and the material waste is less. So, this machine must be the one that can maximize the benefits for users.

As we all know, the best profit period in any industry is in the first few years, and people often complain about themselves: "It's too late!" Today, China's flexo printing is just such an opportunity for manufacturers. Perhaps the flexo printing machine may not immediately see a huge return, but the people who earn the spire of gold in this market a few years later. It must be the one who starts acting now.
