Drupa 2000 look and feel

First, digital printing has become a new technology development trend

In this exhibition, the largest exhibitor is Heidelberg. Xerox became the second-largest exhibitor but it was unexpected for our Chinese audience. The company defines its business as providing equipment to the "new printing business." The so-called "new printing business" refers to some new printing businesses that are sent out due to the application of computers. it includes:

1) Some companies provide customers with products that are difficult to predict their product configuration and quantity in advance. Product documentation is also required to be produced at the same time as the product's production line. These files are provided by a computer database and need to be printed in real time.

2) Like some personalized files, variable information files.

3) Digital book production, which is on-demand book printing system. The company has reached an agreement with Bertelsmann Publishing Group in Germany to develop a digital book printing business.

4) The need for printing due to the application of the Internet, such as the printing and delivery of long-range documents.

Speaking of the printing market formed by the "new printing business," we can offer Heidelberg, which provides mainly analog technology to the printing industry, 150 years of history and annual revenues of 5 billion US dollars. While Xerox only developed electronic printers only about 10 years ago, the company’s revenue in the printing market has now reached $3 billion, and 90% of it is related to digital printing equipment. The purpose of Xerox's business is not to compete with the traditional non-digital offset printing press for the market, but to open up a "new printing business", that is, the digital printing business.

From the history and performance of the two companies, digital printing is a rapidly growing market. Digital printing debuted at the Drupan 95 exhibition, where neither speed nor cost could compete with offset printing. However, digital printing has undergone tremendous changes in the past five years. Digital printing has occupied a large part of the market that originally belonged to offset printing. If we have not yet seen the outline five years ago, then today the market has been colorfully displayed before our eyes.

At this exhibition, digital printing is the new market goal pursued by most exhibitors who produce printing equipment. Some traditional offset printer manufacturers, including Heidelberg, Manroland and KBA, have started to produce and sell digital presses in the face of this situation. Heidelberg launched its own black and white digital press Digimaster and color digital press NexPress at this exhibition. Manroland also reached an agreement with Xeikon to sell Xeikon digital presses. KBA also started selling Indigo's digital presses. .

Traditional prepress equipment suppliers are also catching up with this trend. Screen also launched the TruePress V200 black-and-white digital press. It is said to be the fastest digital black-and-white printer at present, capable of printing 400 pages per minute, and the speed of offset presses is no longer available. the difference. The company also increased the speed of its digital color presses, and currently the company's two color presses TruePress 544 and TruePress 744 are attractive products. TruePress 744 can print 8000 B2 color pages per hour. In 20 minutes, the machine can complete from the plate to print 1000 color pages. This machine can use traditional offset inks and paper.

Barco and Scite also have digital presses. In addition to continuing sales of the Xeikon press, Barco collaborated with Xaar, the famous manufacturer of piezoelectric inkjet printheads, to develop a roll-type digital press using inkjet technology called the.factory. The machine is quite innovative and can be printed on a variety of materials such as paper, plastics, aluminum foils, and resin materials. The inks used are also varied, such as water-based inks, oil-based inks, solvent-based inks, and UV inks.

Xeikon, Indigo and Xerox, which exhibited digital presses on Drupa 95, exhibited their latest products.

Xeikon introduced the Xeikon CSP320D, a sheet-fed digital color printer. This is an upsized A3 format sheet-fed, four-color digital press. It can print 960 A4 double-sides per hour and is equipped with a digital control system. The machine is mainly produced for customers who are interested in digital printing machines, want to use sheet-fed machines, and have a monthly printing volume of 100,000 copies. These customers include small and medium-sized commercial printing plants, export centers, platemaking companies, and fast printing. Shop and in-house printing house.

Xerox launched the DocuColor 2000 Series Digital Color Press. The series includes two models, DocuColor 2045 and DocuColor 2060. Xerox hopes that its digital color printing technology will be a pioneer in the industry and will help the company develop the digital color printing market.

Indigo has introduced a new generation of digital presses: Series 2, which uses multiple units to increase the speed of printing. Series 2 includes a new set of products that are faster and better quality. Among them, it may be the fastest high-quality digital printing machine currently available. It is possible to print 8,000 A4-size color products at a small cost, and the cost is also greatly reduced.

The products of the above three companies have already been introduced in the fifth edition of this year's "Printing Technology" and will not be repeated here.

In terms of the mechanism version, only Drupa 95 had GTDDI from Heidelberg. This year, many manufacturers have introduced products. Manroland introduced Dicoweb, a web press using CreoScitex's direct platemaking technology. At the exhibition, we can also see many companies that combine the production of direct plate-making equipment with the production of printing presses, such as Komori and CreoScitex, KBA and CreoScitex, Adast and Presstek, Akiyama and Presstek, Sakurai and Presstek. Plate printing machine. Presstek is a pioneer in the mechanism version. At Drupa 95, Heidelberg's GTODI used the company's technology. At the exhibition, it played the slogan "We are DI" and exhibited the company's technology at the booths of many printing companies.

Second, CTP technology is more colorful

CTP systems using violet lasers as light sources have become popular. It is said that this is because the light source used to be a light source for a DVD device has a large demand and is therefore inexpensive. This laser is simple, easy to control, highly accurate and has low heat. At the exhibition, Galeeo Violet of Agfa's CTP technology, Viking of Barco, P-9600 of Fujifilm, Platinum 2218 of HighWater, LaserStar of Krause, and ImageMaker of Purup-Esklfot, etc. were exhibited.

In recent years, the infinitely-enhanced thermal plate making technology has not been deterred by the emergence of violet laser technology. On the contrary, new progress has been made. The exhibition exhibited a thermal direct platemaking technology that does not require post-processing, which not only improves production efficiency but also contributes to environmental protection. Therefore, it is also a product expected by the market. The products on display include GaleeoTalant from Agfa and Trendsetter400 from CreoScitex.

Purup-Eskofot has exhibited a new CTP system with new technologies, which are said to change the future of the CTP market and replace the thermal imaging technology that is currently popular in the CTP market. The system is called DICON, uses a UV light source, can be quickly exposed on the traditional negative and positive PS plates, and can use a plate with a thickness of 0.15-0.4mm, instead of using a version specially made for CTP. material. In addition to being suitable for newspaper printing, DICON can also make flexo plates. At the exhibition, the use of UV light source for imaging technology, as well as BasysPrint's UV-Setter direct plate-making system, the use of UV light source, is also a direct plate-making new technology appeared at this exhibition.

From the exhibition point of view, laser imagesetters are no longer a hot spot for technology, and direct platemaking technology seems to be the leader. However, from the perspective of the market, direct plate-making technology is only just entering the market. It is said that there are 60,000 imagesetters worldwide, and the number of direct plate-making machines is only 3,000-4,000.

The use of direct plate-making technology on a large scale in our country still requires a relatively long process. At present, the newspaper system has begun to try to use direct plate-making technology. However, as commercial printing, including publishing, printing, packaging, decoration, and printing, the conditions for using the direct platemaking technology do not seem to be mature enough. The reason is not that the technology is not mature but related to our production scale and production methods. Our printing plant has low platemaking capabilities and the scale of platemaking companies is small. The plate-making technology requires that the enterprises that use it have enough plate-making volume for its consumption. A plate-making machine produces 20-30 plates per hour and it should work 8 hours per day. Enterprises need to have such a large amount of data to satisfy the direct plate-making equipment. The request.

I remember that four years ago, after the Drupa 95 exhibition, I saw a document that listed several conditions that a company needs to adopt CTP technology. Some may not be suitable for the situation in our country, but so far it still seems that we can take it for granted. These conditions include:

Over 1.50% of the pages are Postscript format files;

2. Postscript format prepress system has been used for at least 2 years;

3. Already used a facing or fully open photo machine;

4. Already used digital copy software;

5. Digital proofing system has been used;

6. Use rotary or open, full-open sheetfed printing;

7. At least 3 printing machines with more than 10 color groups are in use;

8. The proportion of re-printing is less than 5%;

9. Usually the business volume of printing is less than 100,000 impressions;

10. Film consumption exceeds $100,000 per year;

11. Printing plate consumption exceeds 6,000 square meters per year;

12. The annual turnover exceeds 8 million US dollars.

It is said that as long as these requirements are met, companies can purchase CTP systems and can recoup their investments within 18 months. At the same time, the data also lists several conditions that, if satisfied, can eliminate the use of a CTP system:

1. Get a very good price from film distributors;

2. Phototypesetter can produce polyester version.

Use Soft Flip to output the page to the film via the large format camera. This can greatly cut down on the cost of consumption, the basic realization of the CTP function, and can save the purchase of CTP equipment, digital proofing equipment and CTP plate costs.

This last one is very important. If the above requirements use a large format photofinisher, it will lay a good foundation for the future use of the CTP system. Otherwise, if you use the CTP system in one step, you will face a lot of confusion.
