How to improve the digital printing output

Speaking from the dispute over the advantages of digital printing

Mr. Kang Minjia in the "When Digital Printing Can Be Popular - Writing in the capital of the first "Aijiang" digital printing machine installation" article that "at present, depending on the use of equipment brands and models, Beijing's digital printing The advantage range of printing (compared with offset printing) is only between 300 and 500 printing, and the digital printing industry should have a strong competitive advantage that cannot be revealed.” The implication is that compared with offset printing, Beijing digital printing The dominant print range may range from 300 to 500 impressions. Kang Weiyi, who is engaged in the digital printing business, believes that the company cannot do anything in practice. According to Lu Weidong, Kang Wenweiyi's “print volume advantage” is printed at 30 in color, and black and white is 100. So, where are the ways to improve the benefits of digital printing?

Dr. Mark Fleming Uses Demand Curve Theory to Increase Print Volume

In 1994, Indigo and Xeikon launched a color digital printing system with an ambitious desire to capture the color on-demand printing market with monochrome digital printing. It is even estimated that within a short period of time, it will be able to compete with traditional printing within 5,000 prints. It is known that prices were traditional at the time. 30 times of printing, the market failure. The fiasco of Indigo and Xeikon also revealed the real problem of price bottlenecks. So far, the price is still a big bottleneck. Dr. Mark Fleming, a US publishing and printing expert, found a moderate solution to the problem. He thinks DemandCurve can be used to describe the relationship between consumption and price and to estimate sales. Market analysis and production planning are also very useful. He believes that the price of digital printing can only be expanded if it finds its “critical point” price compared with the traditional printing at a low price. The critical point for digital color printing is 5 cents per page. His view later in the XEROX with 5 cents as the cost target for the launch of DocuColoriGen3 directly led to the price cuts of major manufacturers and was confirmed. The progress of monochrome digital printing has been relatively smooth. At present, it has almost replaced the traditional printing of short prints. At present, digital color printing has begun to reduce prices.

Obviously, in this regard, the promotion of equipment suppliers is very important.

Virtuous market environment can give birth to reasonable digital printing advantages

At present, China's digital printing market is still immature, resulting in either equipment or products, their prices are not close to its value! On the one hand, people think that the price of digital printing is too high; on the other hand, there are a lot of vicious competition in the industry. In October last year, when Lu Weidong was interviewed by the author, he once said that the price of the digital printing market in 2005 was 20% lower than that of 2004 as a whole. According to his own observations, he also cited prices of A3 color printing in different periods in Shanghai and Beijing to prove: Shanghai market 2005.1-2005.6 is 2 yuan/print; in 2004, it is 2.5-3 yuan/print; in 2003, It is 3 yuan/print. The Beijing market is between RMB 2-2.5/in between 2005.1-2005.6. In fact, on the Chifeng Road where Tongji University was located in Shanghai, there was already a vicious phenomenon of using the DC8000 digital press A3 to beat 1.5 yuan/card, and Beijing even had a phenomenon of 1.6 yuan/card. It should be said that any industry focusing on price warfare can only be said to be immature, and only when the price is infinitely close to the value can it be stopped. This is the law of commerce.

Many netizens also stated that the price of digital printing is now chaotic. You are lower and you are lower. The business is getting worse and worse. Even some netizens hope that they can form a unified price for the coalition. Do not engage in price wars. Quality.

In fact, precisely because the “quality” of the digital printing industry has not yet emerged, such an irrational environment will certainly leave people in a quandary. Then, a reasonable price will give rise to a reasonable advantage in digital printing. (Note: Offset comparison). In response to this phenomenon, industry associations, companies, and the media must stand up and stop the spread of vicious competition with practical actions.

Talking about Several Anti-counterfeiting Means of Printing

The anti-counterfeit printing technology was mainly applied to anti-counterfeiting of securities such as banknotes, cheques, bonds, and stocks. With the development of the market economy and the increasing impact of counterfeit and counterfeit goods on famous and high-quality goods, printing anti-counterfeiting technology has been widely used in commodity packaging. In the field, various new anti-counterfeiting printing technologies are still emerging.

First, printing anti-counterfeiting technology

Early packaging anti-counterfeiting began with the printing of beautifully-made packaging. Commodity producers make packaging more exquisite than ordinary prints, more complex and gorgeous designs, special shapes and unique packaging design to achieve anti-counterfeiting purposes. With the continuous development of science and technology, a variety of anti-counterfeit technologies have been produced, developed and matured in various subject areas, and their application range has become increasingly widespread. At present, there are various anti-counterfeit printing technologies widely used at home and abroad.

1. Printing technology security

1 Plane and convex printing and multi-process printing. General high-end packaging and decorating printed products are designed with a large area of ​​color, multi-color sequence of continuous tone screen and complex lines, patterns, etc., to a single printing method has brought a certain degree of difficulty. If the use of plano-convex printing, that is, the use of letterpress printing press pressure, the ink evenly prints a large area of ​​solid color, with lithographic presses press the soft strength of printing four-color continuous coordination of complex lines, so that the advantages of avoiding weaknesses, the effect of It is very obvious. For some more demanding and more complex prints, multiple processes such as flat and concave can also be used. In short, the more complex the printing process and the more difficult printing products, the better the anti-counterfeiting effect.

Gravure printing technology. Gravure printing means that the graphic part of the printing plate is a raised printing method. The ink printed on the printed picture is also convex. The graphic lines are clear and distinct, and the touch can feel. This printing technology has both protective and anti-counterfeiting properties for paper.

The type of gravure printing is divided into two types according to the plate making method: engraving gravure and etching gravure. The anti-counterfeiting effect of hand-engraved gravure printing is better, and it combines with anti-counterfeiting ink technology to obtain a double decoration effect. If the gravure printing uses fluorescent ink, it not only guarantees the gravure feeling of gravure printing, but also guarantees the use requirements of fluorescent ink. Both functions are guaranteed.

Laser holographic iris security printing. Laser holographic iris printing uses laser holography to make a stencil in a shockproof room, and then transfers the graphic to some kind of carrier through a certain pressure. Its product is at 45. Under the illumination of a point light source, a unique rainbow-like effect can be produced, and the three-dimensional image is extremely strong. Its technical features: The product looks beautiful and exquisite, decorative, strong anti-copying performance, low production cost (only a few cents per square centimeter), fast, effective, no tools to identify, as long as there is light Places can see 2D or 3D graphics and rainbow effects. In addition, the holographic photographer uses the laser light source in the shockproof room to take up the amplitude information and phase information of the scene lightwave in a very short time. The light interference principle is used to form each particle of the scene and form all the information. During the plate making process, the fine air flow in the room may cause the color change of the holographic image. Therefore, it is impossible to make two identical hologram plates anyway. At present, China's technology has reached the level of similar products in the world.

Special glossy printing. Special glossy printing is a new type of printing technology that has become more popular in the packaging printing industry in recent years. Special glossy printing processes currently include metallic gloss printing, pearlescent printing, pearlescent printing, refractive printing, variable gloss printing, crystal gloss printing, anti-metal etching printing and matte printing. Among them, metal luster printing uses aluminum foil metal composite paper with transparent ink to form a special metallic luster effect on printed products. Pearlescent printing is the first printing of silver paste on the surface of the print, followed by a very transparent ink, the silver glitter reflects a pearlescent effect through the ink layer. Refractive printing is the unique effect of using a refraction plate to imprint a picture on a printed article with a certain pressure to produce light refraction. Matte printing uses matte ink printing or ordinary ink printing and then covers the matting film, which can produce the weak luster feature of the enamel, so it also has a relatively safe anti-counterfeiting effect.

2. Paper security

At present, there are mainly watermark banknotes, security papers, and fluorescent papers, which are suitable for anti-counterfeit printing of banknotes, certificates, and bills. Identifying these technologies does not require special tools and can be identified with eyes, ears, feel, or UV light.

Security paper. As a new development in the field of anti-counterfeiting technology, anti-counterfeit paper has its advantages in the following aspects. First of all, it is the holographic pattern directly on the paper, remove the plastic information layer, so it is rarely copied. Secondly, this anti-counterfeiting paper can be designed and made according to the requirements of the merchants. It can produce different textures and different weights of paper (70~400g), such as coated paper, cardboard, and cardboard, and it can also be like Offset printing, screen printing, etc. are the same as plain paper, which is both reliable and convenient. Third, its price is only equivalent to 1/10 of the new defense label, and it eliminates the labor cost of labeling and is easily accepted by manufacturers. Fourthly, products that are directly packaged with such laser anti-counterfeit paper can not only play a role in anti-counterfeiting, but also be beautiful and do not cause environmental pollution.

2 watermark paper. During the manufacturing process, watermark paper can use technical means to incorporate the required logos and patterns into the paper. These patterns are not easy to see under normal circumstances. Only when facing the glare can we see that most of the larger denominations issued in China are Watermark paper printing is used. In addition to being used in currency paper, water FI]~E has also been widely used in other ticket papers.

The watermark paper production process was invented by Italian papermaking experts in the 13th century. Because it integrates the complex processes of design, engraving, web making, and papermaking in the manufacturing process, it makes the counterfeiters useless and helpless.

8 security line. The safety line means that a metal wire or plastic wire is placed in the middle of the paper during the papermaking process. The earliest use of the security line was special gold wire, and the plastic wires used today have been developed into various types, such as miniature letter security lines and fluorescent security lines. The shape of its safety line is a straight line, a wavy line, a sawtooth line, etc. China uses straight line safety lines in currency paper.

Red and blue fiber or colored dots. In the papermaking process, red-blue fibers or colored flakes (dots) are incorporated into the pulp, or scattered on the surface of the paper before the paper is unfixed, and are fluorescently reflected under ultraviolet irradiation. The red and blue fiber yarns and the color dots have a fixed position and a non-fixed position in the paper.

3. Ink protection

Safe ink (anti-printing ink). The ink used to prevent tampering, forgery, smearing, etc. is called a security ink. Its main components are composed of redox compounds, water-soluble binders, fillers, stabilizers and preservatives. In accordance with the process of manufacturing inks processed into a semi-flow gel, to achieve the printing performance. For example, the use of security ink in bank cash, the amount of capital and the amount of lowercase cheques transferred to vacancies, altering the printing vacancies with the eradicator solution, immediately chemical changes, showing the color, to achieve the purpose of anti-counterfeiting. This ink must be printed with a letterpress or offset printer. However, due to the presence of redox compounds in the ink, redox reactions occur during long-term exposure to the air and the anti-counterfeiting function is lost.

Fluorescent ink (hidden ink). An ink made of an inorganic pigment or an organic pigment capable of being colored by irradiation of ultraviolet light with a laser light is called a fluorescent ink (or a leuco ink). The manufacturing method is: using pigment (dye) to add a certain proportion of resin oil binder, filler and stabilizer
