The hottest label flexographic printing era is com

  • Detail

The era of label flexographic printing is coming.

the domestic label industry has been in a high-speed development trend in recent years. The annual growth rate is close to 30%, and label processing enterprises have also received unprecedented development opportunities. Most of the label processing enterprises started from the small label printing machine with inclined back. After a period of development, they have increased the intermittent or full rotation letterpress label printing machine. With the continuous growth of business, label printing enterprises also have some puzzles, mainly in the following aspects. If the damage is severe, the tension spring (1) should be changed. Customers always look for suppliers with lower prices and ask for price reduction

(2) eternal customer quality complaints. For relief printing enterprises, the most common quality problem is color difference

(3) customers' requirements for different processing technologies of products

(4) the efficiency of the production department always contradicts the delivery date required by customers. The total amount of customers' products is increasing, but the number of orders each time is getting smaller and smaller

(5) how to expand their own scale to seek development

in the face of these puzzles, let's first take a look at what foreign label processing enterprises do. 7 American label printing enterprises all use narrow width flexographic printing machines; Almost all label processing enterprises in Europe used relief printing machines 20 years ago, and then began to use flexographic printing machines. Today, most label printing enterprises have switched to flexographic printing machines; Label processing enterprises in Japan, South Korea and other Southeast Asian regions began to shift from relief printing labels to flexographic printing labels five years ago. Why do these label processing enterprises shift from relief printing to flexographic printing? 7 because flexographic printing has helped them solve their puzzles in development

the two basic choices of flexibility are the characteristics of thermosetting plastics and thermoplastic printing

let's first analyze the characteristics of flexible printing

(1) UV inks are compatible with water-based inks. We are glad to cooperate with Masdar Institute of science and technology in these important fields. The price of cooperative inks is 1/5 of that of UV inks

(2) the ink color on the embossing roller used in flexographic printing is very stable; Thick ink layer and high color saturation; The photosensitivity of the plate is stable, and the consistency of the reprint printing of the product is good

(3) there is no restriction on the process space of the unit type flexographic printing machine, which can better adapt to the diversified needs of the processing process

(4) the flexographic printing machine adopts the design of short ink path and rapid plate change, and the cleaning time is short. When changing products, it only needs to replace the embossing roller, doctor blade and plate roller, and it does not need any tools

(5) the machine is fast and suitable for high-speed and large-scale production. All these features have found a solution to the above confusion

misunderstanding of choosing flexographic printing equipment

although flexographic printing can solve the confusion of label processing enterprises, it is easy to enter some misunderstanding of choosing flexographic printing equipment, resulting in investment failure. To sum up, there are the following aspects

(1) I think imported famous brand flexographic printing machines must be very expensive. In fact, flexographic printing machines are only used to process labels, There are very affordable models

(2) it is believed that flexographic printing machines can only be used to process long plate jobs. To be exact, flexographic printing machines are suitable for repeated product production. Some label printing enterprises include the plate cylinder and die-cutting cylinder in the cost of a certain product of their customers. The calculated production cost is very high. In fact, these cylinders should be considered as fixed investment and can be used for the production of other products

the plate making cost of flexo is higher than that of letterpress. However, if allocated to multiple printing, the plate making cost is not high. In addition, if the printing plant prints the plate itself, the cost is not higher than that of letterpress. Now many suppliers can provide small flexible plate printing equipment

(3) the multi-functional combination printing process itself is a major advantage of flexographic printing production line over other printing equipment, but the multi-functional combination should be rational rather than arbitrary. It is necessary to select the appropriate machine according to the product and market positioning of the enterprise, and select the configuration with a little surplus than the current demand to meet the needs of development

choose a high configuration flexographic printing machine and even configure a machine to be omnipotent, including water-based ink printing, UV ink printing, printing, gravure printing, offset printing, hot stamping, die cutting and slitting, etc. each printing method has its own characteristics, which can not be matched. Secondly, the machine configuration has too many functions, which is very difficult to operate, and the production stability and efficiency will inevitably be lost. Moreover, too much configuration and not being used at the same time will inevitably lead to a waste of investment. In short, the highest return on investment is the key consideration of the enterprise

(4) superstitious about servo technology. They think that any problem can be solved by using servo transmission. Servo technology can not improve the accuracy of the machine, but help to improve the response speed of the machine, which is meaningful for the processing of expensive label materials

case 1

before 2004, Guangdong ~ label processing enterprises owned ~ intermittent relief ep$~j machines and two oblique back small label e printing 1$j machines with impact resistance. The main products produced are drug labels and some scattered labels. In 2004, the business has developed to 24 hours a day throughout the year, which is difficult to meet the needs of customers. At the same time, because there are other competitors, Customers have repeatedly asked for price reduction. The products printed with UV ink on relief printing machines have made meager profits and can not bear the pressure of price reduction. In 2004, the enterprise purchased a 13 inch wide flexographic printing machine from Madison and chose a mature and stable model. On the basis of meeting the production needs of existing products and considering the future business development, it has configured 8-color full hot air drying and UV curing plus a printing unit and a cold hot stamping unit 。

after the introduction of the flexographic press, the products that had been repeatedly processed for many times were put into production on the flexographic press. As a result, the products that originally took one month to complete on the relief press were completed on the flexographic press in only five days. There was no delivery pressure, and there was still plenty of time for enterprises to develop other businesses and require customers to place more orders. In addition, the use of water-based ink instead of UV ink on the flexographic printing press, coupled with the faster turnover of raw materials, quickly reduced the production cost, so the enterprise made profits to customers and got more orders

the printing unit and cold hot stamping unit are configured to help customers design some new products with silk printing effect and transparent laser cold hot stamping effect, which are highly praised by customers. Due to the two printing methods of full UV ink and water-based ink, they received an order for processing 28 types of film materials for a well-known American company

before the enterprise purchased the flexographic printing press in 2004, the annual output value was 10million yuan, The profit is 2million yuan. The annual output value increased to 25million yuan in 2005. The profit increased to 4million yuan. In addition, the enterprise's output value and profit increased significantly in 10 days of machine idle time. In addition, the business space increased significantly.

(5) the new functions of the machine will always attract the attention of customers. However, it is necessary to identify whether this function is mature and the future application direction. If this function is not mature or it is just a transitional technology (it will be eliminated due to changes in materials or processes in the future). It is necessary to carefully select

(6) it is also very important to select a responsible professional supplier. Flexographic printing is a new thing for label processing enterprises. After all, they have limited knowledge of new things. It is easy to be confused by the sales skills of salesmen. It is best to choose machines with a large number of installations and good operation conditions on the market

the author has worked in the industry for many years. He has witnessed many successful and unsuccessful cases of flexographic printing labels. Here are a few cases that you may learn from

coupled with a substantial increase in competitiveness, this is a successful case

case 2

a label processing enterprise in the North has many label businesses. It chose a flexographic printing machine produced by an internationally renowned flexographic printing equipment manufacturer. However, the machine they bought was the model produced after the supplier purchased a small factory. This machine has never been sold in China and is mainly used to process some low-end products abroad. However, the supplier boasted that it is a high-end machine. In addition, because the supplier has very little installed capacity in China, the experience of service personnel and sales personnel is also limited

after the installation of the machine in 2006, it was found that the efficiency and accuracy of the machine could not meet its needs, and the service personnel of the supplier were unable to solve the problem. As a result, the enterprise could not produce normally. This project basically failed. In the process of introducing equipment, there were two problems: first, the machine was not selected correctly. In fact, there were many mature schemes in operation in China, but the enterprise did not choose well; The second choice is the wrong supplier. Choosing an experienced, powerful and honest supplier is the first step to the success of the project

case 3

another domestic enterprise when other enterprises are choosing multiple processes and high configuration, their choice is a stable, mature and simple Mai andI 4150 machine. What they see is the advantages of fast flexographic printing, environmental protection of water-based ink and low cost. They develop some suitable product markets according to the advantages of flexographic printing

as a result, they can complete the products suitable for this machine with the lowest cost and the highest speed. The machine is equipped with a non-stop unwinding mechanism, 7 water-based ink flexographic printing units, 1 UV glazing unit, sheet cutting and automatic collection devices. The machine has been producing at a speed of more than 140m/min for many years, The product qualification rate is over 93%, and the annual output value of a machine exceeds 40million yuan. It can be imagined that the return on this investment is very rich
