In 2008, drupa printing exhibition Shanghai Debao full sheet offset printing machine world premiere, CHINA PRINT2009 after Speedmaster XL145/162 came to China. Compared with the well-known German offset press manufacturer, Heidelberg has launched a full-length machine, but it has a tendency to rise. With the industry reputation gained by offset press products for many years and the long-term accumulation of printing machine manufacturing technology, Heidelberg has introduced XL145/162 with 1450mm and 1620mm format based on the variable data printing for the needs of the Chinese market. Long, set "high quality, high efficiency, low loss". Through the analysis of the author below, you can learn more about the Speedmaster XL145/162 representative of the Heidelberg full machine.
Heidelberg Speedmaster XL145/162
First, XL145/162 configuration details
Standard configuration
The whole structure: The whole structure of XL145/162 fully considers the principle of ergonomics, the operation is more convenient for rubber products, the production is more efficient, the whole machine has a larger area than similar models, so the structure will be stronger. To meet the production needs of the company for 24 hours without stopping.
Operation concept: The large size means that the printing plate is large and the paper is large. In theory, the label is more difficult to start and the four-start operation is more difficult, so more labor is needed. In order to improve production efficiency and reduce labor, in the operation concept, Shanghai Debao has done a lot of optimization on the XL145/162, which makes the whole machine operation very convenient. For example, the latest version of the Prinect Center has been reduced by about 70% from the central console of Heidelberg; the touch screen controls digital printing at the Feida, called the "second central console", which can be controlled Most of the functions of the entire machine; there is also a touch screen and operation wheel and buttons at the delivery. From the current feedback situation, most operators think that it is easier to operate such a large machine than to operate it.
The printing material Feida part: XL145/162 continues the XL family's enhanced Feida. This Feida design is simple and stable digital printing machine, easy to maintain.
Intelligent paper-passing system: The XL145/162 is equipped with an intelligent paper-passing system. The sensor, monitor, etc. automatically monitor the entire transfer process of the paper, and the distance between the blowing volume, the blowing surface, and the paper and air-cushion paper guide. Make adjustments at all times to ensure that the paper is not dirty or scratched during the transfer process, achieving an ideal paper-printing digital printing without manual intervention.
Fully automatic plate changing system: As standard, the XL145/162 plate changing system is a fully automatic plate changing system. Whether it is 6 color groups or 8 color groups, the plate changing can be completed within 2 minutes. The model saves at least 2/3 of the plate changing time.
Automatic cleaning system: In order to improve production efficiency, XL145/162 is equipped with automatic cleaning system. At the same time, it can be equipped with synchronous cleaning device. Ink roller, blanket roller and impression cylinder can realize synchronous cleaning, which greatly reduces the preparation time.
Double-circuit independent temperature control system for ink roller and ink fountain roller: This system is very important for the user of the whole machine, especially for the packaging business. It can effectively control the temperature history of the ink and finally make the printing suitability of the ink. A constant state is reached to maintain the consistency of the ink color of the print. If it is not in the standard configuration of the XL145/162, it will be very difficult to control. As the machine is running, the temperature of the whole machine will increase the fidelity printing. Although there is air conditioning in the factory, it is difficult to maintain the ink color of the printing. Consistency, and this is also more advantageous for the control of the shop temperature.

Polishing unit: The replacement of the glazing unit plate and the anilox roller can be completed by one person, and the operation efficiency is very high. For partial glazing, replacing a resin plate requires only one person to spend 2 minutes; if different thickness varnish quality control is required, then it takes less than 3 minutes for one person to change the anilox roller.
Extended delivery system: The XL145/162 standard delivery length is 8.25 meters, which is twice that of the same model. This results in a better paper transfer effect, and the paper has a longer transfer time before it reaches the delivery stack, making the ink on the sheet easier to dry completely. At the same time, the delivery device can also be equipped with different types of drying devices according to the needs of the production process, such as infrared hot air drying, UV drying system and the like. It is worth noting that the XL145/162 is superior to the competitors: there is a temperature control system scan based on the surface of the stack, the sensing device monitors the drying temperature to confirm the amount of dry energy, and automatically adjusts the drying energy according to the feedback, ultimately making The surface of the print is dried to the best. In addition, with the extended delivery system, the average production speed of the XL145/162 is 2000-3000 rpm higher than that of similar models, which means more than 2000-3000 sheets per hour, so even the XL145/162 is open. By the time it is nominally 15,000 sheets/hour, you can still get a dry print, which is truly a promise of higher efficiency.
Dusting system: At present, there are high and low end points in the powder spraying system on the market. According to our understanding of printing inspection, the XL145/162 is equipped with the best in the world. It has specific metering devices and special nozzles to get the most. Good dusting effect, so it can reduce the amount of dusting powder by 50%-60% on average, which is beneficial to the protection of the workshop environment. Lekai 2 glue, but most importantly, the reduction of powder usage is packaged products, The downstream processing of commercial prints brings more convenience, because once the powder is less and more uniform, it is very advantageous for some packaging products that require post-press processing such as film coating.
Peripheral equipment: Water supply and gas supply devices are all peripheral devices commonly used in printing presses. They have the same impact on production as the mainframe. The XL145/162 has a number of peripherals for color management and is high-end. For example, the air supply equipment, XL145/162 uses a variable frequency air supply system, and two sets of systems compensate each other, and automatically adjust the number of revolutions according to the amount of gas used. All similar designs are built around the main line of machine downtime to ensure machine reliability and stability. Optional device It is no exaggeration to say that the standard configuration of Heidelberg XL145/162 is very luxurious, so there are not many options available to you here, but it is still full of features and prices.
Inpress Control On-machine control system: This system is installed behind the last unit of the printing press. It can detect the color and registration condition during the operation of the machine, and automatically adjust it. In the past, the operator saved the situation when viewing the sample. Lost. It is understood that this Inpress Control Prinect in the machine control system of Heidelberg has been awarded the "GATF Technology Award" in 2008 for the start-up and four-boot universal, and has won high recognition from internationally renowned industry technology awards.
Folding synchronous cleaning system: Synchronous cleaning system is very useful for full-sheet machine. The previous cleaning system was firstly used for washing ink roller, blanket and embossing roller. With synchronous cleaning system, it can be cleaned synchronously. Because domestic labor is cheaper, printing companies are currently using manual cleaning, but the device will play a greater role as domestic labor costs rise and work hours are very demanding. Printing and Packaging City II. One sentence summarizes the biggest advantage of XL145/162. Based on the top standard configuration and the best ergonomic design, Heidelberg XL145/162 has 20%-30% higher than the competitive model. Production efficiency, less manual input color sequence, whether it is a long version of the job or a short version of the job, can be competent.
