10:07 China Printing [font size: large, medium and small]

offset printing, inkjet, toner and direct imaging (DI) have their own advantages and disadvantages. Their advantages and disadvantages can also be shown through printing format, quality level, output and cost. When selecting printing equipment, printing service providers mainly consider the following factors: printing size, space constraints, quality level, output and budget

how should printing service providers make investment decisions? Faced with so many technologies, how can they choose their own models according to the cost performance and the type of moving parts? The comparison of printing technology has never stopped. The change of printing methods and the rise of production-oriented inkjet equipment have taken shape as early as a few years ago. Today, we will conduct a detailed and in-depth analysis on different printing technologies, the choice of printing buyers and the intersection between various printing technologies

offset printing technology

offset printing plants are usually engaged in high-speed printing of large quantities of static documents. They only pay attention to quality and speed when selecting equipment at the joint of A. screw and base. Although many people are promoting the benefits of digital printing, offset printing still has a place in the market. Jimhamilton, general manager of win boat, said: digital printing is difficult to beat offset printing in the field of long plate printing

in the process of offset printing, the operator should print the plate through film or make the plate directly by computer, then transfer the pictures and texts on the printing plate to the blanket in the order of water first and then ink, and finally transfer the pictures and texts to the paper through the blanket. Offset press can print on a variety of substrates, and some special coated paper is no exception. Large format offset printing equipment is mainly used in the production of newspapers and other large format products

although high-quality printing can be carried out in large quantities, offset printing also has its own shortcomings. It uses solvents in the production process and has certain requirements for the technical level of operators. In addition, the floor area of the offset press is generally large, and the printed matter cannot be personalized produced directly on the offset press. Variable data live parts can only be produced in a mixed way: the static cover is printed on the offset press, while the personalized content is produced on the digital press

offset printing and other traditional printing methods, such as gravure printing and flexographic printing, have certain advantages in long version printing and substrate compatibility. Although the quality of digital printing has been significantly improved in recent years, it still can not meet the needs of some applications

digital printing technology

in order to improve marketing efficiency, the current market demand for short version personalized printing is also increasing. With the help of the digital printing machine, which can produce short version live parts in a more economical way, printing service providers can achieve on-demand printing while shortening startup settings, plate making and drying time

digital printers are usually small in size, do not need too many operators, and can perform online post press processing such as wireless binding and book making. These unique functions make the digital printing press popular in the fields of on-demand printing, short edition publication or marketing material production

unlike offset printing machines that produce fixed images, digital printers can print variable information on each page. This has brought good news to the enterprises that produce marketing materials and transactional documents

digital printing technology is mainly divided into electrostatic photography, toner, piezoelectric, thermal and continuous inkjet. Electrostatic photography mainly completes the printing process through electrostatic charge, photosensitive drum, toner, light and fuser

xerographic printers generally use dry toner, while HP uses Electronk electronic ink, which can print through the position of printing particles

high speed inkjet equipment usually adopts continuous inkjet or on-demand inkjet. Continuous inkjet printheads can continuously produce ink drops, while on-demand inkjet printheads can only produce ink drops as required

although they are all digital printing, there are great differences in the speed, quality and operating cost of each technology. Electrostatic printer is better than ink-jet printer in color saturation and substrate compatibility, but the speed and cost efficiency of ink-jet printer are better. The characteristics of different equipment often confuse printing service providers when choosing printing machines, especially when they want to enter a specific market

Bobraus, product marketing manager of Riso, said: electrostatic printing is the benchmark of digital printing, but it seems to have reached the limit in terms of speed and cost, and inkjet technology is improving the productivity and cost efficiency of digital printing to a new level

raus explained that companies such as HP, Procter, Kodak and Ossi can now provide customers with high-speed continuous paper feeding inkjet printers, and their production capacity and speed are also constantly improving. However, the price of such equipment is generally high, and it is more cost-effective only when the monthly output of users is between 5million and 10million pages

in contrast, Riso's comcolor sheet fed inkjet solution seems to be more suitable for enterprises just entering the digital printing market. Whether direct mail suppliers, service organizations or commercial printing plants, as long as their monthly output is between 10 and 20million pages, they can use this equipment to produce

riso recently commissioned interquery to compare the response rate of the same page produced by the ink-jet printer and the electrostatic photographic printer. The result shows that the latter has a higher response rate. Although the cost of printing postcards on electrostatic photographic equipment is about 62% higher than that of inkjet equipment, it still does not hinder users' love for this equipment. At the same time, this also raises a new issue for printing service providers: are they willing to give up quality for the sake of cost

digital printing machine is suitable for a variety of environments, but it also has some limitations. For example, the speed of digital printing machine is slower than offset printing, and many devices can only provide four-color printing services. In addition, most sheet fed machines print between 11x17 inches and 14x20 inches

for long version static moving parts, the digital printer has no obvious cost advantage, but with the emergence of high-capacity color inkjet printer, all these have changed. The use of multiple digital printing engines brings users a medium and long edition printing solution that is better than traditional offset printing

direct imaging technology

direct imaging printing machine has more automation functions than traditional offset printing machine, but its stability and quality are still inferior to offset printing

through the digital imaging technology, people can make digital documents into four on-line chemical free printing plates, which not only reduces the production steps, reduces the plate making time, but also improves the work efficiency. Presstek is the inventor of this technology and has sold its right to use it to several companies including Heidelberg

in 2008, the company entrusted Yingchuan company of the United States to conduct a survey. The results showed that the operation preparation time of the direct imaging printer was 23% to 38% shorter than that of the traditional printer

52di printing machine is the fist product of pressek company. Its price is $525000, and it can reach the resolution of 2540dpi and the maximum speed of 20000 pages/hour. This printer can accommodate a substrate with a maximum size of 20.47x14.76 inches. Presstek34di printing machine sells for 275000 US dollars. Its maximum speed is 14000 pages/hour, and the maximum substrate size it can hold is 13. Zigzag tests are often used in production to evaluate the zigzag strength and plastic deformation of materials 39x18.11 inches

34di and 52DI printing machines adopt waterless printing, which has low maintenance cost and no special requirements for paper

di printing machine can only print two sets of four colors before, but the new 75di printing machine recently launched by pressek at the IPEX exhibition has rewritten this history. This printing machine can print four colors, five colors and six colors, and has the ability of six printing, which can significantly improve the productivity of the printing plant. It is understood that 75di will be officially listed at the end of 2010

selection of printing service providers

after understanding the advantages and disadvantages of electrostatic photography, offset printing, inkjet and di printing machines, the printing service providers will make a choice. Jiayu is the relevant knowledge about the common anomalies in the operation process of the spring change experimental machine shared by the technicians today. Ighton, the product marketing manager of ISG production system group, an American company, suggested that by understanding the price, technical capacity, application field, output requirements and version transfer time of the equipment, users can narrow their choice range

printing service providers' choice of technology mainly depends on business needs. In addition to printing quantity, enterprise type, paper processing, post press processing and binding, they also need to consider the transfer time. They must ask themselves: what is the development direction of the enterprise? Our strategy is that we can give you more detailed answers at any time? Can these equipment meet our development requirements

many manufacturers have their own flagship products in the field of electrostatic photography and inkjet. In the past few years, some leading equipment suppliers have launched new products one after another. Recently, HP and Xerox launched new inkjet equipment on the premise of consolidating the electrostatic photography market. In addition, through the acquisition of Ossi, Canon also has the conditions to participate in the competition in the electrostatic photography and inkjet market. It is worth noting that Konica Minolta, which has always kept a low profile, also recently launched the press product line for the printing market

weigh the pros and cons

offset printing, inkjet, toner and di printing machines all have a place in the commercial printing market, and each technology has its own excellence. Therefore, before making investment decisions, printing service suppliers must comprehensively consider their own strength, space, production requirements and needs for special functions

some people may ask: is the printing quality as important as before? The answer is No. In some solutions, printing quality is the most important factor, while in some application fields, it can only reach the general level

no one will hang bills or direct mail on the wall for exhibition. In 70% to 80% of cases, we do not need to use photo quality prints, especially in the current economic environment. Under the impact of new media such as Internet communication and e-mail, the printing industry must speed up the pace of adopting new technologies, keep up with the trend of time, and deliver high-quality color prints to customers at the lowest price
