At present, the high, medium and low ends of corrugated box printing represent products and processes.
• The high-end is a pre-printing process. The printed color roll is combined with other corrugated medium and inner paper to form colored cardboard, which is then die-cut.
• The middle end is printed on cardboard, which is flexibly printed on corrugated cardboard, commonly known as post-printing.
• The low end is that the cardboard is not printed. Due to the point-to-point commercial supply mode in the e-commerce background, only the paper label containing the necessary product information on the carton can meet the demand.
The high-end products bear the sales and packaging function of the carton, and the low-end products bear the transportation and packaging functions of the carton, and the performance and requirements are very clear. The mid-end products are more complicated. The products in this section must have the functions of selling packaging and also the function of transportation and packaging. Therefore, the cost and quality of the carton must be balanced, and the products must be adjusted at different times according to different customer needs. Focus.
However, this kind of consideration is often unpleasant, and it is very likely that users will be spit out when they are unable to look at each other. The rubber engraving flexo and photographic liquid flexo are mostly concentrated in this section. Mid-end carton products are the focus of market competition for a long time to come, and turbulence and change are inevitable themes.
Relatively speaking, as a high-end product corrugated box pre-printing, the market turmoil is relatively small, and the development trend is more obvious.
Carton preprinting in China is the first to get started from the flexo printing process. Under the condition of maintaining the compressive strength of the original carton, the pre-printing process can save 20% to 30% of paper weight, which is an effective way to tap the potential of the carton industry. Therefore, the technology landed in the domestic carton industry around 2000. Inevitable.
Since the process is an exotic product, the pre-printing process began with the custom of foreign countries from the beginning of flexo printing. However, due to the inherent aesthetic concept of the domestic market, the domestic printing industry's deliberate pursuit of printing quality, when the flexographic printing process is still unable to meet the perfect requirements of consumers, the carton gravure pre-printing process came into being. Even if the gravure preprinting process has higher requirements on paper, the paper cost is much higher than the flexo printing process, but the difference between the 175lpi image of the gravure printing product and the 133lpi image of the flexographic printing product makes the flexo preprinting quite similar. Opponent. At the same time, the sluggish printing market in recent years has prompted some offset printing companies to switch to the field of packaging and printing. Because offset printing can also meet the short-term demand for carton printing, and rotary offset printing has the advantage of low cost of PS plate. Also broke into the carton pre-print market.
In this way, in the pre-printing market, which is not very large, the “Three Kingdoms Kill” is extremely fierce. The focus of the game is on printing quality and manufacturing costs. Whoever can lead in both print quality and manufacturing cost will win first. Therefore, it is particularly necessary to evaluate the role, status, advantages and development of flexo preprinting in current corrugated box printing, which determines the market response strategy of printing companies.
Flexo preprinted material cost composition
Flexo preprinted material costs are divided into three major sections, namely paper, plates and other consumables. Generally speaking, in the material cost structure of printed matter, the printing material accounts for about 50%, and such products have a certain profit margin. There are continuing development prospects. However, at present, domestic printing companies often encounter high prices of printing materials, resulting in printing materials accounting for 60% of the cost, and even more outrageous, even 70% of the record. Therefore, for the corrugated box industry, the procurement of printing materials is often directly responsible for the general manager, because there is a slight negligence in paper prices, it is possible to overturn the cost. The flexo preprint process is no exception, and controlling the cost of paper is often the first factor in controlling manufacturing costs.
1. Paper
Flexo is a embossing that uses a embossing of the anilox roller inking mechanism, so as with all embossing, it is not picky about paper. It is well known that the printability of paper is often characterized by the characteristics of the paper coating and the thickness of the coating. Paper coatings with high print quality requirements are thicker, finer and more expensive.
Due to the paper coating, the paper must be selected when using the gravure printing process. Otherwise, the dot transfer is incomplete. In addition to the high-gloss dot, it is not easy to print. The middle adjustment area or the flat screen is also prone to small white spots. The use of electrostatic ink absorbing devices on the gravure printing machine can solve the problem of dot transfer, but the printing on the ground is not uniform, and the characteristics of the surface fiber are deep and shallow.
The offset printing process also needs to select paper. If the coating quality is slightly poor, the viscosity of the ink itself during high-speed printing may cause the ink film to be anti-adhesive to the paper, and it is necessary to add a viscosity reducing agent to the ink to avoid. If the surface of the coating is too loose, the dust is easy to precipitate, and the frequency of stopping the rubbing and wiping the blanket is obviously increased.
The flexo printing basically does not pick the paper, no matter the thickness of the coating, it can be dealt with the printing plate of different hardness; the flexo printing uses the liquid ink, the cohesion of the ink itself is not high, and the ink film is not damaged due to the excessive viscosity. The flexo prints the ink by pressing the surface of the printing plate, and the ink forms an ink film by the permeation absorption of the capillary pores of the paper under the action of the positive pressure received by the printing plate. Therefore, even if the coating is thin and the quality of the paper is poor, there is often no reason for returning the goods in the flexo. Flexo claims to print almost all materials, of course, this does not rule out advertising factors, but flexo printing can "eat coarse grains" without having to deliberately pick paper, which is beyond doubt.
The adaptability to different quality papers makes flexo take the lead in controlling paper prices. With this one alone, flexo printing is slightly better in controlling the cost of printed matter. This is also the case. The price of the paper roll required for flexo preprinting is significantly lower than the price of the paper roll required for gravure preprinting. Because of the weight of paper prices in flexographic preprinted products, the advantages of flexo printing are evident in the quotation of individual products.
2. Plate
The high cost of the edition is a plague brought by flexo. This is because we have no domestically produced flexo version more than 10 years ago, and basically all flexo versions rely on imports. Imported plates cannot be sold at high prices. In recent years, the market expansion of the domestic flexo version has stabilized the price of the flex version, but the obvious price difference between the thin plate and the thick plate has affected the competition of different processes in the cost of the plate. In the soft-printing world, when it emphasizes its own advantages, it always likes to say that the printing plate has a printing durability. Compared with offset printing, flexographic printing has an advantage in printing durability. However, the market has changed, and the short-term and single-day increase has not been so large. There is no demand for the printing durability of the printing plate, and the flexo printing loses its advantage in this respect. Using the PS version of the web offset printing into the carton pre-printing market, the challenge is the flexo printing fee.
3. Other consumables
In addition to paper and plates, the cost of flexo printing in consumables is primarily ink. Flexo preprinting uses paper ink, which is not costly. However, the double-sided tape used for flexo printing is an important aspect of the cost of flexographic preprinted consumables. Because of the buffering of the inking pressure or the printing pressure during the flexo printing process, the flexo printing process uses a double-sided adhesive of a foam structure. Such double-sided tape is currently mainly imported, and the cost of use is about 100 yuan / square meter. In addition, there are no other special consumables for flexo printing. The metal scraper is similar to the gravure printing. It does not have a special effect in the comparison between gravure preprinting and flexographic preprinting.
