The use of high technologies such as contemporary digital technology and computer network technology in printing machinery has undergone major changes and qualitative leap, and has achieved a high degree of automation, information and intelligence. The development of printing machinery technology presents the following major trends:
Networked printing workflow started
　　 The networked printing workflow is the process of promoting integrated production through the solutions of several suppliers. This working method utilizes an open architecture, networked and automated equipment, and adopts open standard intelligent integration to adopt the industry standard JDF (Job Definition Format) and PDF (Portable Document Format) for seamless information exchange. Intelligently through various systems, from desktop design to print shop, the entire design information of printed products can be transmitted from publishers, advertising agencies, or production centers across the space, time, and area to the platesetter, printer, and postpress. equipment. To achieve a networked printing workflow, you also need servers, Inktone network interface, Infinova front-end software, and Integrity network interface software to achieve long-distance Internet transfer of live jobs, proofs, and signatures. Creo, headquartered in Canada, and Xerox, the United States, have teamed up and successfully launched experimental prototypes controlled online. This technology integrates the workflow of the entire printing process resources, which greatly shortens the publishing cycle. It is expected that a market will soon be formed in the news publishing industry and a new round of network system design import peaks will be formed. At the 2003 China International All In Print Show, Mr. Garron Helman, President of Creo Asia Pacific, in addition to introducing the products debuted by Creo at All In Print, described the future marketing initiatives of the company. Outside the product, it will focus on promoting the development of digital media, printing value, and networked printing. Creo Company regards digital media, printing value, and networked printing as its future product growth points and market growth points. It is expected that its sales revenue will reach 1 billion yuan in 2007.
CTP technology represents the development direction of printing equipment
CTP technology includes three concepts, namely, computer to paper, computer to plate, and computer to press. Western developed countries have successively mass-produced direct platesetters, direct proofers, digital printers, and inkjet printers developed by CTP technology. The major suppliers of direct platemaking machines, such as Creo, Sai Angel, Agfa, and Screen, have proposed a variety of direct platemaking solutions, including direct thermal plate making and photo-sensitive direct plate making. The fastest direct plate-making machine in the world has a plate-making speed of 170 sheets/hour and a four-plate version of 350 sheets/hour. There are many types of plates for direct platemaking machines, including silver salt plates, photopolymer plates, photopolymer plates (for flexo printing), polyester plates, PS plates, and thermal ablation plates. The emergence of direct plate-making machines made traditional photography and plate-making equipment—laser imagesetters, cameras, and printing machines and other equipment faced with strong market competition. Some experts predicted that by 2010, laser photo printing will exit the European and American markets. Digital presses can also be used in a variety of ways, such as digital presses in the mechanism version, offset digital dual-use printers, "non-printed" digital presses, inkjet printers, and integrated machines. Digital presses now have the trend of industrialization, breaking the world of offset printing. Among them, the D146 of Heidelberg is printing on the mechanism printing press, Israel's unprinted digital printing press, and the ideal all-in-one printer, printer and copier. The market has already threatened the office printing market and photoengraving equipment represented by small offset presses; the other wing of the digital press—the Heidelberg D174 and Manroland digital presses—can realize both traditional offset printing and direct image printing. This large-format printing also poses a threat to the traditional offset printing market; large-format inkjet printers can produce street, body advertisements and wallpapers, which pose a threat to gravure printing machines and screen printing machines. Digital presses are currently suitable for "short-run" printing or personalized printing, and they cannot pose a threat to large-volume printed newspapers, books, and packaging. With the rapid development of the market economy, “short-run†and personalized prints will increase rapidly. According to statistics, in 2003, more than 3,000 printing plants in the United States used CTP technology, and the rapid spread of CTP technology equipment was a foregone conclusion.
Green Printing Market Expansion
Flexographic printing is a letterpress printing method, which was developed after solving photosensitive resin plate and plate making equipment, water-based ink, anilox roller and engraving equipment. Flexo printing press is an automatic production line that mainly prints in flexographic printing and incorporates multiple printing methods and auxiliary functions. Its successful trial production mainly depends on the combined configuration of flexographic printing and coating, screen printing, cross-cutting, and bronzing, and can fulfill the production requirements for specific trademarks, folding cartons, and flexible packaging products at one time. This equipment does not have the problem of ink-ink balance, the ink path is relatively simple, the ink is quantitatively transmitted, and the water-based ink meets the requirements of environmental protection.
Taking the change trend of world packaging printing as an example, the proportion of flexographic printing in the packaging field will further increase. Flexographic printing in foreign countries has expanded into press and publishing and flexible packaging, especially in Europe and the United States. At present, 40% of the packaging printing in the European packaging and printing market is offset printing, and the development of flexographic printing is also very fast, accounting for 32%. It is reported that there are more than 400 flexographic printing companies in the European Union with a certain scale. The number of countries with large numbers are 950 in Italy, 800 in Germany, 650 in Britain, 500 in France, and 350 in northern Europe. In recent years, flexographic printing has also become a major focus of the North American packaging paper product printing industry. According to the statistics of the North American Flexographic Technical Association, more than 6,000 flexographic printing companies in North America had a total printing production value of more than 85 billion U.S. dollars in 2003, an increase of 5%, and flexographic printing accounted for 74% of the North American packaging printing market. It accounts for 24% of the world's printing and publishing market. The covered market segments include soft film packaging, paper bag multilayer packaging bags, labels, corrugated paper pre-printing, folding cartons, and envelopes. It is estimated that by 2005, flexographic printing in the world will surpass offset printing, accounting for 39% of the packaging sector, while gravure printing will account for 15% and other printing methods will account for 10%.
In addition to flexible flexo printing, some foreign companies currently use water-based environmental inks and anilox rollers for quantitative ink transfer on offset presses. This is also a promising approach to environmental protection. Other green printing machinery and equipment include water-based UV printing equipment, water-based UV polishing machine, dry laminating machine, and water-based laminating machine. The technical problems of these products have been solved.
Printing Machinery Automation Level Up
The automation level of printing machinery is mainly manifested in four aspects: mechanization, stand-alone automation, automation of auxiliary operations and automation of printing product production processes. In the printing process, manual operations that have not yet been mechanized are mainly done after printing. Many bookbinding companies (folding, collating, pasting) and newspaper distribution (insert pages, pages, and bundles) are still manually operated; Prepress, there are companies using hand-made puzzles. These operations can be completely solved by the bookbinding equipment and the automatic layout system of newspaper automatic distribution equipment. The lower level of single-machine automation in the printing process is mainly reflected in the pre-press and post-press, such as the printing machine, copy machine, paper cutting machine, hot stamping machine, die-cutting creasing machine and so on. Now that these devices have been replaced by newer products, high-end equipment such as Germany's Porache paper machine, Switzerland's Bobst die-cutting hot stamping machine and automatic platemaking machine can greatly enhance the automation level of the printing process. Printing machine-assisted operation automation, mainly for high-end offset press has been widely used in addition to frequency control, PLC, CP window, CPU, CPC, but also used automatic register, ink balance and nonlinear tracking, paper automatic conversion preset , Automatic paper wear, automatic rubber washing, automatic plate change, automatic paper, automatic reversed double-sided printing, rewind function, cut sheet features and other mature technologies. This high-end offset press mainly comes from foreign companies such as Heidelberg, Manroland, KBA, Komori, Mitsubishi, and Goss. The automation of the printing product production process includes two aspects: one is the transfer of printing information, that is, the digital workflow, which is solved by the interface of standardization, software and hardware; and the other is the connection of the equipment used in the printing process, as the world has already solved. Book printing and binding once into a book device.
There are also some devices that have already implemented a variety of functional configurations, such as a variety of printing methods and the combination of cutting, die-cutting and gilding of flexographic printing presses; printing, punching, punching, rewinding, and glossing of form printers. ,Coated charcoal, horizontal and vertical lines, open the transformation and other functional combinations; Cutter also realize the paper, page, score, cut paper, transfer, paper, die-cutting automation. In recent years, in order to maintain independent intellectual property rights and corporate interests, it has been widely used in the printing of print or securities.
