core tip: the label market follows the development model of the global printing market, that is, single batch decline, mass production is replaced by personalized/multi version. The reason is partly because consumers have completely changed their buying habits under the influence of Internet and social media; In addition, it is affected by new technologies, especially digital printing machines. The printing volume continues to rise as a whole, but shows a trend of small batch and multiple versions

[China Packaging News] the changing market demand will change the production plan and bring opportunities to new technologies. But which is the right choice, and how to maximize its potential

this white paper evaluates the current situation of the label market, summarizes the applicable technologies, and uses industry resources to compare and analyze the cost of existing printing technologies, helping printers choose the most appropriate technology for the produced prints

today's market

the label market follows the development model of the global printing market, that is, single batch decline, mass production is replaced by personalized/multi version. The reason is partly because consumers have completely changed their buying habits under the influence of Internet and social media; In addition, it is affected by new technologies, especially digital printing machines. The printing volume continues to rise as a whole, but shows a trend of small batch and multiple versions

as a brand operator, in order to respond to the changes in market demand, we must adopt the technology that can produce on demand (JIT) in time to meet the increasingly common requirement of completing the order within eight hours from order to delivery. In addition to more small batch operations, the number of SKUs has also increased rapidly, with small print volume and many versions. If flexographic printing technology is used, the effective production time is less, but the cost increases. In addition, variable data is used for product tracking, promotional activities, games and credibility programs. These changes have promoted the wide application of new ways of thinking and new production tools. This white paper statistically analyzes the typical labeling work and decomposes its component costs, which has guiding significance for actual production

competitive technology

the self-adhesive label market is relatively young, and its production technology and material development began in the mid-20th century. At first, the narrow width rotary machine mainly concentrated in the range of mm. After changes, the printing technology has changed from relief wheel to flexographic printing and offset printing, supplemented by silk screen and gravure printing units to complete special moving parts or post-processing. With the emergence of UV curing and CTP technology, ASTM e547 (2) 00, a standard test method for rainwater leakage of external windows, skylights, doors and curtain walls under cyclic static pressure difference, the questions of reversing sparks and brush wear have severely restricted the implementation of DC closed fatigue life testing machine. The improvement of 0 and corrugated rollers and the improvement of ink have made the quality of flexographic printing exceed that of embossing, and narrowed the gap with offset printing. Now, in terms of the number of printing machines installed, UV flexo printing plays a major role in the narrow rotation production of the label market. 7.2 inspection items are also combined with other printing technologies, such as silk screen printing, post wiring processing, such as hot/cold pressing, film coating and glazing

digital technology is the product of color printing in the 21st century, although inkjet has existed for many years. At present, label production mainly adopts two technologies: Toner (liquid or dry powder) and inkjet. Plus flexo printing, these three technologies have their own advantages and disadvantages compared with each other, and have been widely used all over the world. Toner technology is only applied to digital printing (with/without wire processing), while the flexo/inkjet mixer recently launched in the inkjet market can carry out the multi-functional combination printing mentioned above. In addition, the latest series of inkjet printers can complete one-way production together with self owned brand offline and online post processing systems

comparison of total production time

cost analysis also needs to consider other costs, such as materials, inks, plates, preparation time and other consumables

it can be seen from the above figure that the total cost of inkjet and flexo printing is similar, but the composition ratio is different. The cost of inkjet ink is high, but there is no plate making cost in printing, which is suitable for the production of short single variable versions, such as personal care market and other fields with high SKU. In the current market environment, the pressure of production tends to reduce the downtime of printing machines rather than higher printing speed - time is money, and downtime means loss of profits. The ability to complete a printing job in 20 minutes is more important than the 60 minutes or more between downtime and restart wasted in the printing workshop

another important factor in selecting the best technology is its applicability. The emergence of high-performance UV curable ink has injected unprecedented vitality into color labels. This kind of ink can also maintain excellent durability and wear resistance in harsh environments, such as high humidity, chemical or salt water conditions. Therefore, in the commodity and home care markets as well as the industrial label market, UV inkjet technology has more advantages than toner technology. In addition, the performance of white ink in inkjet technology can be comparable to silk screen printing, and is significantly better than flexo printing and toner white, which makes inkjet technology open the personal care market. In the food market, UV ink is not popular because of the possibility of harmful substances migration in theory, but in practical application, at present, most food packaging has successfully used UV ink and coating, and there is no problem. As reported by the media, the key is the quality inspection mechanism and control in the production process

in general, UV technology, whether inkjet or flexo, has a wide range of applicability. At present, UV inkjet is the key to unlocking profits with the trend of short order, multi SKU and JIT delivery in the market
