Heidelberg

Heidelberg launched the world's first set of 50 with eight color configuration × 70 "Speedmaster equipment is equipped with two sets of paper turnover equipment, online coating system, extended paper receiving system, etc. Speedmaster SM 74 has the "one-step" production function. This production method requires high-precision printing technology when printing four-color activities, so as to avoid the scratch and dirt of the paper in the process of transferring to the receiving stack. SM74 equipment is also the first to produce magazine packaging paper or eight page instructions coated on the surface

Heidelberg Speedmaster SM74 eight color printer with page turning device and coating system improves the paper feeding guide of the paper transfer unit. The Heidelberg Venturi principle guides the paper smoothly through the transmission units under the protection of a cushion formed by air. For 4/4-color operation, the precise paper drying configuration of the equipment is particularly important, and the control and positioning should be precise and accurate. The continuous paper transfer unit features two infrared hot gas dryers and a Heidelberg drystar cycle dryer, which can be used in coordination with the paper guide

the maximum printing speed of the demonstration prototype can reach 13000 sheets/hour. The SM 74 eight color printing machine without page turning and coating configuration can increase the printing speed to 15000 pages per hour by adopting a new paper guiding method, that is, 30000 pages per hour

other innovations include new narrow paper braking devices and paper guides, which are also used in some equipment

komori

komori's lithrone 28 perfector double-sided printing machine has a special three minute face changing function. The company improved the double drum printing and transfer ink rollers and applied them to the lithrone 28 "and 40" double-sided printing machine systems to obtain the maximum paper processing area. Lithrone 28 perfector also adopts this roller arrangement to obtain a smooth paper conveying process, less scratches and stains, and higher positioning accuracy. This design not only protects the paper, but also ensures the correct positioning in high-speed printing

lithrone 28 perfector double-sided printer the conversion between single-sided and double-sided printing is automatic. Because the AMR function of the console allows the paper size data to be input in advance, when the operator selects double-sided direct printing, the paper size adjustment is automatically carried out, and the subsequent operation of changing the gbt8363 ⑴ 987 ferrite steel drop weight tear test method is also fully automatic. The lithrone 28 perfector is also equipped with a backup system, which includes a manual control box that allows the paper rotation drum to reverse automatically

ryobi

ryobi company launched a four-color offset press with semi-automatic plate changer (semi-automatic plate changer) developed by its own company - Ryobi 3304ha equipment, which runs vertically, and the printing size is slightly larger than A3 format. Semi automatic plate changer allows users to control the replacement of printing plates by pressing a button. In addition to using metal plates, the device can also use polyester base plates output by the plate setter. In addition, a new diagonal adjustment device is installed on the plate clamp, which greatly simplifies the positioning adjustment during printing and ensures a shorter preparation time for short version live multicolor printing

3304ha is designed on the basis of 3304h. Ryobi described 3304h as the world's first A3 size four-color offset press with longitudinal paper feeding, with simple design, high efficiency and cost saving. The basic specifications and features of 3304ha equipment are the same as those of 3304h. The four printing units are composed of two sets of satellite V-shaped five roller systems, which reduces the replacement of paper teeth and improves the accuracy of image positioning. In addition, the equipment's continuous wetting system "Ryobi superd ampener from the government level" takes the optimized fountain solution supply as the standard. The maximum paper size that 3304ha can handle is 13.39 × 17.72”。 The maximum printing speed can reach 10000 sheets/hour. The standard pcs-f printing control system includes a console to remotely control the ink fountain

xeikon

plastic card manufacturers can now use the dcp/32s digital color printing machine of Xeikon company to print short editions. This equipment has attracted more and more attention. Xeikon plastic card production solution can not only print on PVC materials, but also feature the use of Melzer's multi-function system for post press processing, such as film coating, die cutting, and embedding magnetic strips, panels, microchips, holograms and other contents. The advantage is that it reduces the operation cycle, meets the short edition of printing on demand, enhances the ability to customize products for customers (personalized or descriptive cards), and can carry out flexible operations

dcp/32s equipment applies Xeikon's electrostatic printing engine, which can print five colors (four printing primary colors and one opaque white) on the standard coated PVC surface, with a printing thickness of 10 mils and a speed of 24 feet per minute. The front and rear ends of each drum can accommodate two complete 12.06 "wide paper jams. The system can print digital documents directly without printing plates. It is reported that it is faster and more flexible than the traditional equipment in case of looseness

dcp/32s can handle various cards, including multi-layer composite products and intelligent instrument components. In addition to the typical four layer card (two layers of PVC materials are compounded on both sides of the card respectively), the system can also produce multi-layer cards with a core layer sandwiched between the two layers of PVC. This core layer can contain antennas similar to those contained in RFID (FM radio identification) cards
