4. Automatic detection device Manroland on-line print inspection device installs a camera on the printing unit of the last color group to perform video inspection on the printed matter. According to the quality standards, the quality control of each printed sheet is performed, and the identification and identification of the printed sheets are eliminated. Defective sheets are transferred to another paper table in the delivery device, thereby reducing waste in the finished product.
Color measurement and control can scan and measure print control strips located on the edge of a printed sheet or in the middle of a printed sheet. The print control strip is not only very small, but also has a plurality of measurement blocks required for the adjustment of the gray balance, which is the best quality control method in sheet-fed offset printing presses.
The KBA QualiTronic online sheet inspection system scans printed pages and compares them to reference proofs at high speeds, identifies unqualified sheets, automatically removes them during die cutting or folding, and can also use Double-sided printing machine. KBA's Tronic Professional has an on-line monitoring system with density measurement and control that can standardize density with just about 60 sheets.
5. Temperature and Humidity Control System The multi-function temperature control system maintains and controls the optimal temperature at start-up and shut-down by measuring the temperature of the main ink roller to reduce color adjustment and stabilize print quality. The ink roller temperature control and cooling system keeps the surface temperature of the ink roller constant, reduces the ink ink deviation and stabilizes the printing quality. The cooling system employs water circulation between the ink fountain roller and the ink fountain roller to control the temperature of the ink roller.
The central water-cooling unit and the internal control system can control the indoor temperature, reduce the heat, improve the printing quality, reduce the airflow speed, and reduce the pollution and noise.
Fourth, full-featured combination of processing 1. Short-ink ink supply system Short-ink ink supply system uses anilox roller short ink inking device to achieve ink-free keys, waterless printing. KBA Genius 52 UV is the first offset printing machine to use anilox roller short ink inking method. In Drupa 2008 KBA also demonstrated 3 waterless offset printing presses, namely sheet printing machine Rapida 74 Gravuflow, 74 Karat DI. And web printing machine Cortina.
2. Large-format offset presses High-speed and high-efficiency are the main melody of the development of modern presses. The efficiency of presses is reflected by the printing speed and the printing format. At the same printing speed, the larger the printing format, the higher the efficiency. Therefore, the development of large-format offset presses, especially large-format offset presses, has become a new type of printing equipment, expanding the use of offset presses and increasing production capacity.
Large-format offset presses have reached a high level in terms of print quality, automation control, and operating performance. They can print high-quality, multi-level prints, periodicals, maps, postcards, posters, etc., and can also print corrugated cardboard and plastic sheets. Wood and other substrates can also be equipped with on-line slitting devices to promote the development of packaging and printing.
Large-format offset presses have high efficiency and wide application range, but they need to purchase corresponding pre-press and post-press matching equipment, such as large-format plate making equipment, paper cutters, die-cutting machines, folding machines, coating machines, and laminating machines. .
3. Double-sided offset printing technology The variable mode of single-sided multi-color printing and double-sided printing is not only meeting the user's requirements for high efficiency and flexibility, but also the demand of the printing press market. The Heidelberg Speedmaster XL105 double-sided printing press with paper turnover device is based on the technical advantages of a single-sided printing machine, which increases productivity by 40%. KBA Rapida 142 eight-color printing machine also has a flip function, flip printing conversion time only takes 1 minute to complete two-sided four-color printing.
Double-sided printing can also be used in non-inverted form, with double-sided alternating printing and double-sided printing separately. Akiyama MEGA JP4P440 large double-sided four-color offset printing press adopts double-sided alternate printing. There are six rollers for each color group's positive and negative printing device. After printing one color on the front and back, pass it to the next color group to complete four-color printing. . The machine has high stability and reliability and can achieve a printing speed of 15,000 sheets per hour. (To be continued)
