Analysis on the market application and development prospect of Di printing machine (Part I)

since the first introduction of di (direct imaging) printing machine in 1991, with the advantages of in-machine imaging, it has made many achievements, especially at the drupa printing exhibition in 2000, it has attracted the admiration of countless insiders with its extraordinary performance. Some people even assert that the offset press in the future will be the world of di. However, times have changed, and this good wish has not been realized. The ordinary protection of Komori, Sakurai, and hydraulic universal testing machine among the original developers should pay attention to the following problems: timely liquidation of concrete samples and other parts such as iron filings. Le, Adast, Akiyama, etc. have successively faded out of the di printing machine market. By 2004, only a few Di printer developers had appeared at the drupa printing exhibition. The development of Di printing press seems to have entered a stage of stagnation and contraction

however, there are still enough reasons for people to be optimistic about its market potential. According to the prediction of "industry trends" in the United States, by 2010, 43% of the printed matter will have less than 2000 copies. In other words, the future printing market will be more inclined to short version operation. The main market target of direct imaging printing is short edition printing. In addition, di printing machine fully caters to another development trend of the printing market - digital workflow. The adoption of new processes such as water offset printing also makes the application scope of Di printing machine wider. Therefore, the market prospect of Di printing machine will continue to be promising

analysis of the current situation and development trend of Di printing machine products

at present, there are only a few developers left in the di printing machine market. The existing products mainly include the following:

· Heidelberg Kuaiba Di printing machine. This is an octave four-color waterless offset press, which adopts pearl imaging technology and pearldry plus printing plate technology of pressek company. In December, 2002, Heidelberg announced that it would provide the printing plate selection scheme of Saphira caleidoplate 46 for the professional and upgraded users of Kuaiba Di printing machine

· Heidelberg speedpa 74DI printing machine. It belongs to the four open multicolor offset press, which adopts Cleo's imaging technology and the traditional water moistened version scheme. The professional 74DI printer can provide a console based on CP2000 and an optional infrared drying device. According to statistics, 95% of users of speedpa Di printing machine choose the five color or six color scheme, 75% of users choose double-sided printing, and 100% of users have installed coating and glazing devices at the same time

· leyoubi 3404di printing machine. This is an octave four-color water free offset press, which uses the Profire imaging head and pearldry printing plate of pressek company. Lyubi's 3404di printing machine can add infrared drying devices. In addition, printing enterprises can choose printing density control system (pds-e) or printing density control system with color rendering document setter (PDS Pro-E)

· 74 karat printer provided by gaobao. It is a four-way four-color water-free offset press, using Cleo's imaging technology and pressek's pearldry aluminum plate. The main feature is the use of anhydrous and keyless gravuflow ink supply system. Most 74 karat customers choose Di printers with four-color coating devices and dryers

· dicowebdi four-color printing machine of Manroland company. It uses Kerio's thermal imaging head and 740 mm wide web paper. It is the world's most expensive full sheet offset press, suitable for the production of 1000 to 30000 sheets of printing. The biggest advantages include: strong data receiving and processing capabilities; There is no need to change the printing plate for imaging and image removal; There is no need for expensive printing plates, which can be directly imaged on thermal transfer tapes, and can be recycled by Manroland company after use

· screen truepress 344 printer. This is the latest octave (A3 format) four-color Di printing machine developed by screen company. It adopts the latest 830 nm MALD (multiarray laserdiode) imaging technology and Konica Minolta printing plate, with a printing resistance of up to 30000. Using standard offset printing ink, paper and fountain solution, you can choose to configure an infrared drying device

· directpress5034 Di printer of Kodak Polaroid. Kodak baoliguang, a famous supplier of consumables, has also joined the ranks of Di printer developers. The di printer launched by it is octave four-color, with the fuselage of leyoubi as the operating platform, and adopts pressek's Profire imaging technology. Di printing machine has become the third digital printing process product besides CTP and digital printing machine, the two core products of Kodak Polaroid

from the above analysis, the existing Di printing machine products are mainly four open and eight open. The main reason for this situation is that the input cost of Di printing machine with folio and full format is too high. From the perspective of market demand, Bakai printing press will continue to be sought after by the market. In addition, many functional configurations on the high-speed offset press will also be reflected on the di printer at the same time, such as more printer color decks, more online functions (such as coating, glazing, etc.), faster drying system, etc., so as to improve the appearance quality of prints and shorten the production cycle

di printer is suitable for small batch and short cycle color printing operations. It has the quality of traditional offset printing, but the operation time is shorter than offset printing. For the waterless offset Di printer, there is no water ink balance problem, so the printing quality is more stable

taking the printing operation of A3 format, four colors and 500 copies as an example, the completion time of the three printing schemes of imagesetter + printer, ctp+ printer and truepress 344 Di printer is shown in Figure 1 respectively

the adoption of development free direct imaging technology makes Di printing machine have many advantages. First, the live part information in the computer is directly transmitted to the printing plate of the printing machine for imaging, which reduces the influence of various variable factors in the intermediate transmission link, and the printing quality is relatively stable; Secondly, the two links of film production and printing plate (no printing plate on DICOweb) are cancelled, which reduces the printing production cost and shortens the production cycle; In addition, direct imaging plate making does not require the use of developing potions and other environmentally harmful chemicals, and the production process meets the requirements of green environmental protection

the digital workflow has greatly shortened the production cycle of Di printing machine and achieved the 24-hour delivery target. After the di adjustment and clearance printer receives data from Rip, the operator can check the moving parts voucher to understand the paper type, format size and corresponding printer adjustment information of the next moving part, and choose the moving part to be printed next by himself, without waiting for the prepress department to deliver the printing plate instruction of the next moving part

di printing machine covers all processes from prepress to printing. It realizes simple and efficient operation through automation and quality control system, with high overprint accuracy, short operation time, and relatively low requirements for professional technology and skills of operators. However, in case of failure, the printing and plate imaging processes will stop working at the same time, and the enterprise can only find another way to complete the relevant printing operations

As an independent plate making equipment, CTP can provide plates for multiple offset presses at the same time. If it can't work normally, printing enterprises can make printing plates through other ways, so that the production process can continue. In addition, if CTP equipment can be combined with gbt8358 (1) 987 steel wire rope breaking tensile test method for automatic plate installation on the printing machine, it can give full play to their resource advantages, greatly reduce the operation preparation time, improve the production efficiency, reduce the production cost, and make the traditional offset printing machine still have strong competitiveness under the printing volume of less than 300 copies. Theoretically, the investment of CTP equipment can benefit all printing machines within the enterprise, so as to improve the overall production capacity of the enterprise. However, if the printing enterprises introduce CTP equipment only to provide plate making services for the existing old printing machines, they will not be able to give full play to their advantages fundamentally. Because, as an important factor in production costs, the printing time has not changed fundamentally

ctp equipment is relatively expensive, and the supporting high-end famous wolf's law points out that offset printing machines are also expensive, so many enterprises may not be able to afford this huge investment cost. In this case, di printer will be a good choice. However, customers also have to consider the high maintenance cost when choosing Di printer: a set of four-color Di printer system costs tens of thousands of dollars every year just for maintaining the laser head. In short, Di and CTP have different market applications and demands, and each has its own advantages. Therefore, powerful printing enterprises often have two kinds of equipment at the same time

di printing machine and digital printing machine comparative analysis

di printing machine and digital printing machine important distinction lies in: digital printing machine use can become image device, in dynamic way fast printing variable data or image; Di printing machine is specially designed for small batch and short cycle offset printing production, which cannot realize variable data printing

the advantage of digital printer is that it is more like a digital printer. In essence, the content of each page is variable. Its disadvantage is that the printing cost has nothing to do with the print volume and whether there is variable information for live parts. The price of each printed matter is the same. As an offset printing scheme, the cost of Di printing machine will be greatly reduced under the condition of high printing volume

it can be seen that in an ideal situation, there is no competition between the two technologies, and they have their own service scope suitable for them. If you want to print 1000 prints, and require low price, offset quality and immutable page content, di printing machine has more advantages. Generally speaking, the cost of Di printing machine with printing capacity of more than 500 is lower than that of digital printing; The high-speed digital printer has more advantages in the range of 1 to 500 printing volume and variable data printing

digital printer adopts toner imaging technology, which is inferior to di printer in printing quality. As a toner based equipment, digital printing machines need related consumables costs, such as toner cartridges, corona wires and fusing heaters. Therefore, if the digital printer is used to make still images, the added value of the variable image function will be wasted, because the value of this part has been included in the actual payment

in addition, compared with digital printing machine, di printing machine has many other advantages: the printing volume can be as high as 30000; The selection range of substrate is also wider, which can adapt to paper with different thickness and finish; Printed matter is more conducive to folding, indentation, punching and other processes in post press processing

the main reason for the current competition between these two technologies is that the financial budget of enterprises is relatively limited. After all, not all enterprises can bear the high investment of Di printing machine and digital printing machine at the same time
