5. Cross-media publishing technology
Cross-media publishing technology is a part of the digital workflow. Using this technology, text, images, sounds, and video files can be processed for a variety of media products such as print. CD-ROM e-books, web publications, etc.
Heidelberg Company had statistics on the market share of global print media and electronic media. In 1995, the market share of print media accounted for 70%, and electronic media accounted for only 30% of the market share. By 2010, the annual growth rate of print media is 35%, the growth rate of electronic media is 9.5%, print media will account for 48% of market share, and electronic media will account for 52%.
In this exhibition, we can also see a demonstration of the “Books on Demand†system, which can be digitally printed and bound immediately through the Internet according to the needs of users.
With the application and popularization of digital and networked technologies, cross-media publishing technology will be the general trend. The emergence of cross-media publishing technology will inevitably bring about a revolution in the printing and publishing industry. The industry must prepare for this.
6. Offset printing technology
Drupa2000 has a total of 63 manufacturers of sheetfed offset presses and 63 manufacturers of web offset presses. Over the years, Offset Printing has achieved high speed in its platemaking, good printing quality, and has achieved data and standardization in the production process. It can not only print a short version of live, but also can print long-lived prints and other advantages in the market, and it has dominated the market. In books, newspapers. Folding cartons, large format posters, labels, etc. are widely used.
The offset presses exhibited by Drupa 2000 include almost all the format specifications of the web. The color group structure and configuration are flexible, and the maximum number of sheetfed offset presses has reached 12 color groups. Many of the sheetfed offset presses have variable double-sided printing, central control, ink remote control, non-contact paper guide, automatic register adjustment, automatic rubber washing, automatic plate change, and non-stop paper change. The overall development trend is high efficiency, high quality, automation, and high flexibility.
Due to the increasing number of color short-runs in the field of packaging and printing, manufacturers have also launched corresponding equipment to seize the market. Heidelberg introduced the Speedmaster CD74 with a format of 600mm x 740mm, which is specially used for short-run color packaging printing. The machine has an ink speed of 15,000 sheets/hour. There are four-color machines or six-color machines. The double-diameter impression cylinder can print boards. In order to meet the needs of the packaging and printing market, Heidelberg's Speedmaster 102 not only incorporates digital workflow, but also features double-glazing, double drying, even gold printing and silver printing, and double-sided six-color printing can be completed in one go.
Man Rowland's latest sheetfed offset press products are Roland 200, Roland 50O four-color and six-color sheetfed offset presses. Roland 200 format is 52cmx74cm, and the printing speed is 13,000 sheets/hour. The double-diameter impression cylinder can print 0.04-0.8mm paper. Roland 500 printable cardboard with a maximum print speed of 180O0 sheets/hour.
At the exhibition site, KBA's single-sheet offset presses are all connected with KBA's DensitronicS closed-loop color control system. On-site digital platemaking machines such as Lotem800V and LithoSetterV are used for on-site plate making. Corrugated cardboard cylinders are printed on the KBARapida 105 offset press for free distribution. Visitors.
In addition to the continuous use of shaftless and seamless technology, web offset presses have made new developments in terms of enhanced flexibility. Several major manufacturers have introduced color newspaper printing machines with dual-width, small-drum structure without shaft drive. Save on the number of editions and increase the flexibility of reporting. Heidelberg, for example, launched the Mainstream80 printer, which has a ratio of 1:1 cylinders and blanket cylinders. It uses seamless rubber sleeve technology (it can be replaced in 60 seconds), and the printing speed reaches 80,000 copies/hour. Manroland introduced Regioman, which has a tape width of 1260 to 1400mm, an inking speed of 70,000 copies/hour, and cutting sizes of 470, 510, and 546mm. KBA launched the Prisma press, with a maximum print speed of 70,000 copies/hour.
It is worth noting that, at this exhibition, KBA launched a new type of machine Cortina for newspaper printing users. The machine uses a shaftless transmission, no key ink, waterless offset. At the exhibition, KBA used Presstek's Dimension 44 computer-to-plate system for printing, and used Presstek Pearl Dry waterless offset printing, with a maximum printing speed of 80,000 copies/hour. Because the height of the machine is reduced to 3.4m, it is more user-friendly.
In addition, commercial web printing presses are developing in a flexible direction in terms of open size, folding style, etc. It has become a development trend to further shorten the preparation time and improve the efficiency through various automations. Narrow web offset presses add a variety of features, such as punching, embossing, UV drying, etc., to facilitate the printing of forms, direct mail advertisements, and labels.
As can be seen from Drupa2000, offset press manufacturers pay more attention to provide users with a full set of solutions, not just to provide a stand-alone. They are also more focused on integrating their equipment into CIP3 digital workflows to provide customers with digital print production possibilities. Sheet-fed offset presses are developing in more color groups, higher automation levels, and more suitable for short-color printing of color prints. Many manufacturers have equipped their products with dual-glazing, extended delivery, and other devices to meet high-grade prints. Printing needs. Most web offset presses have used non-shaft rotation, automatic plate change, automatic paper feed, on-line color control, central control system, etc. The purpose is to shorten the auxiliary time and reduce the scrap rate. The continuous improvement of folding machines and folding superstructures provides greater flexibility for the production of newspapers and magazines.
7. Flexo and Gravure Printing Technology
In this exhibition, there were 78 exhibitors of flexo printing machines, and 38 exhibitors of gravure printing machines (including 7 sheet-fed gravure printer manufacturers and 31 web-fed gravure printing machine manufacturers). The number of exhibitors of flexographic printing machines is significantly more than the number of exhibitors of gravure printing machines. This shows that flexo printing has developed rapidly in recent years and has become the fastest increasing printing method among various printing methods.
The difference between this show and previous Drupa is that several major manufacturers have exhibited folding carton flexo presses. German W&H company exhibited the Novoflex Cartoline CI six-color folding carton printer at Drupa. This machine plate roller and anilox roller adopts non-shaft technology, printing width is 1000mm, repeat printing length is 300-760mm, can print 500g/m2 paperboard, printing speed is up to 300m/min, suitable for various products folding paper Printing of boxes. The machine can be connected to an on-line platform or a rotary die-cutting machine. On-line printing and die-cutting greatly increase the production speed of folding cartons. In addition, EDALE also exhibited a narrow folding carton flexo press.
Another difference between the current exhibition and the previous Drupa exhibition is that both flexo and gravure printer manufacturers have introduced shaftless drive products, so many non-shaft driven flexo and gravure presses are It is extraordinary to be unveiled at the same international exhibition. For example, Rotomec, Sirodi, Heidelberg, W&H, F&K, etc. have all introduced gravure printing machines with non-shaft drive. Heidelberg exhibited a Gallus RCS330 wheelless drive flexo press at Hall 1. The machine is mainly used for printing labels, printing width of 330mm, the maximum printing speed of 120 meters / min, the use of flexo and rotary screen printing combination, with on-line coating and rotary die cutting. It is reported that the company will also add embossing, hot stamping and laminating machines and offset printing units on it to meet the diverse needs of users.
When it comes to the development of flexo printing, we cannot but mention the development of flexo-printer direct plate-making technology. It is precisely because of the development of this technology that the quality of flexo printing is greatly improved, and flexo printing is used more widely in the printing industry. This Drupa 200O has five manufacturers of flexo direct plate system. Barco exhibited CDI, Creo Scitex exhibited ThermFlex, Hell exhibited HelioFlexF2000, ICG introduced IMPACT system, and ohio introduced Digilas system. Hell's HelioFlexF2000 is the first display on the Drupa 20O0. It can produce single-plate printing plates and sleeve printing plates. The printing plate or sleeve size reaches 1200mmx1600mm. The machine has a high-performance laser head, in addition to the flexible version, It can also be used to make mesh gravure printing plates. The laser head color uses 8 1110nm lasers with a maximum resolution of 2540dpi.
8. Postpress Technology
Drupa2O00 has more than 260 companies involved in bookbinding and finishing. Many well-known manufacturers, such as Martini, Kolbus, and Wohlenberg, exhibited the new machines at Halls 2, 6, 12, 13, 14, and 16, respectively. Type and ancillary systems. From the current exhibition, the main features and development direction of postpress processing technology are:
1 Postpress processing is moving toward digitalization. In this exhibition, many famous manufacturers have participated in the international "prepress, printing, post-press integration" organization - CIP3, exhibiting a corresponding digital workflow management system. In Hall 6 "Printing City", a complete printing workflow program was exhibited. It can be seen that in the fields of commercial printing, packaging printing, newspaper printing and other printing, there are postpress manufacturers who are members of the digital workflow, such as Wohlenberg, Baumann, MBO, Blumer, and Schur. Hohner, Jagenberg and other manufacturers, in the cutting, folding and binding, printing and processing manufacturers and prepress, printing manufacturers, together to achieve data printing process solutions.
2 Post-press processing equipment has a higher degree of automation, a more flexible device structure, and a shorter set-up time.
3 Post-press processing equipment is more diverse.
Third, new changes in printing and publishing
Through the Drupa 2000 exhibition, the trends in international printing technology and the market can be summarized as follows:
1. The digital workflow and cross-media publishing technology combined with the Internet have begun to apply and continue to continue to develop, which will again cause a revolution in the printing and publishing industry.
2. The computer-to-plate technology has been widely adopted, the thermal plate has matured and become the mainstream, and the direct plate-making technology will gradually replace the traditional plate-making process.
3. Machine-to-machine plate printing is developing in the direction of high speed, high quality, large format, and automation, and will gradually replace the traditional small offset printing market.
4. Digital printing is increasingly approaching the quality of traditional offset printing, and is being developed toward high speed, high quality, wide width, and automation. The emerging on-demand printing and personalized printing market is taking shape and will occupy a part of the market for traditional small offset and plate direct machine.
From the DruPa2000, it can be seen that the digitization and networking of information has brought a powerful impact and revolution to the traditional publishing industry, mainly reflected in the following aspects:
1. The promotion and application of the color desktop system enables everyone to become a printer. The division of labor, functions, and organizational structure of the traditional printing and publishing industry will surely undergo differentiation and reorganization. Some of the work originally completed by printing houses has now been transferred to publishing houses, advertising companies, and emerging export centers.
2. The application of digital technology in the printing and publishing industry has enabled the printing industry to gradually develop into a media processing factory. The printing house in the future will no longer be a printing media processing factory that can only accept traditional manuscripts, but media products that can accept a variety of electronic documents or digital information, such as prints, CDs, and nets.
