Heidelberg Speedmaster D174 (Speedmaster D174) is a new type of digital direct imaging printer launched by Shanghai Xiebao. The machine follows the characteristics of digital printing and digital printing combined closely with printing. At the same time, based on traditional printing presses, a digital direct imaging platemaking device is attached to each unit. This machine can adopt traditional lithography and offset printing methods. You can also use this ... (Direct Imaging Press). Unlike the Drawer D146-4, this digital direct imaging press uses a thermal metal aluminum plate, offset ink, and still has a system. The principle is to pass the digital images processed before printing directly to the digital direct imaging platemaking device installed on each unit of the printing machine through the Creo square dot thermal imaging technology. The device has a built-in laser imaging system and can be used in many places. With up to six crews working on the same plate, the entire machine can be finished in 3.5 minutes, and the resolution of the plate is up to 2400 dpi and printing can be started immediately. Digital-laser technology allows direct imaging and direct printing without the need for prepress work such as film, imposition, printing, etc. Special short-run print jobs require fast and high-quality requirements.
The Speedmaster D174's features and features lie between the digital press and the traditional offset press. It also combines the advantages of these two types of printing presses. By using traditional lithographic printing methods and equipment, a digital direct imaging device with a built-in 40W laser can be installed on each unit, which can constitute an advanced digital direct imaging printer, thus completing overprinting. More demanding, faster-speed, multi-color, high-quality prints.
Second, Komori with a super flip mechanism of the printing press, the introduction of a new concept of sheet-fed double-sided printing press Japan Komori production of sheet-fed lithographic printing machine to Lithrone 26,28,40 (L-640, L440) on, on the boot The most common, at the same time, there is the flip function of the Lithrone 26P, 28P sheetfed presses. Almost all of them have the functions of automatic cleaning of the ink roller, blanket, and impression cylinder, as well as automatic presetting of ink and paper thickness, and automatic printing of APC (Automatic Plate Changer) function, which greatly shortens the preparation time of the printing press and the production efficiency. With continuous improvement, the printing speed can reach 15,000 sheets/hour. At this exhibition, manufacturers are still exhibiting on most of the above models to demonstrate Komori's strength and scale.
In addition to this, at the exhibition, Komori also launched the Lithrone 40S and RRSP double-sided printing presses with four- and two-color reversible SPRINT GS yarns and new printing concepts.
SRINT GS series printers can complete one-color printing on one side or both on the front and back, and are equipped with an ink remote control system and functions such as automatic printing, automatic washing roller, blanket cleaning, etc. The floor space is small and single-sided printing can be used. Print paper up to 0.6mm thick. A console with a color corner touch screen, above the delivery table of the printing press, makes the detection and adjustment of printed products convenient and rapid, and the structure is more compact.
The Lithrone SP Series, which was on display at the show, introduced a new concept for sheet-fed duplexing.
The LITHRONE 40SP, 44SP sheet-fed lithographic printing press is a type of printing machine that can print on both sides in a special way. Unlike sheet-fed presses with rollover mechanism and B/B roll, the double-sided printing function of this press comes from the special arrangement of the rollers. It places the front and rear printing units on the upper and lower sides of the machine respectively, adopts a double-diameter impression cylinder, and alternately completes the front and back printing through the transfer of the paper between the impression cylinders. Since each printing unit (including the front and back printing units) adopts the most basic three-roller arrangement instead of the plain roller-rolled B/B roll-to-roll method, it can ensure the printing accuracy; effectively preventing The overprinting error caused by paper overturning and handover reduces the number of adjustment steps and makes the operation easier and more convenient. It also adopts a double-diameter impression cylinder and doubles as a transfer between the units, omitting the transfer cylinder to ensure the minimum number of transfer times for the paper, and at the same time, On the premise of ensuring the convenience of operation, it greatly saves the floor space.
LITHRONE 40SP and 44SP printers can print both front and back (L-240SP, L244SP) and front and back four-color (L-440SP). Compared with non-reversal printing presses, it can reduce the drying time and increase the production efficiency by 2-2.5 times compared with the non-reversal printing presses. Compared with the printing machine with reversing mechanism, it has a simple operation, Overprint accuracy, small footprint. It can be seen that this model combines the printing quality and flexibility of a single sheet with the production efficiency of the web, together with the automatic blanket cleaning device, the automatic paper presetting function, and the automatic printing function, making the 40SP The (44SP) printer can perform multi-color double-sided printing with high efficiency and high quality.
Third, Sakurai's multiple control system to ensure high efficiency and automation of the printing press. The Sakurai company's OLIVER series of four-sheet sheet-fed offset press is more famous. OLIVER-11 does not list out four printing presses for printing a four-color printing - six colors. This series of printers adopts a 7 o'clock roller arrangement design. The double-diameter impression cylinder and the intermediate transfer cylinder are series printing machines with a coating and coal dry (UV/IR) system. Based on the above structure, the OLIVER-ED11 series printer has completed printing when the paper is delivered to the delivery roller, eliminating the impact of the ink bars. At the same time, due to the small number of paper transfers (double-diameter cylinder), small bending deformation, good overlay accuracy, printing of paper up to 0.6mm thick, and the ability to achieve less cloth and drying on-line to meet high-quality, high-productivity requirements .
