MO's high-performance paper feeder can provide a more stable paper feeding process. Positioning and printing units are all pneumatic. Ink and dampening systems all use CP windows for accurate monitoring, which can reduce job preparation time. Can pre-adjust the amount of ink, can be used to start a shorter time to achieve the best ink balance, the use of high-end delivery agencies to meet the long-lived and high-volume prints of paper collection capacity, dusting and infrared drying system, for India The final guarantee is provided before the product is removed from the machine. From the printing format, the superior applicability of the maximum width of 480 650 (MM) and the minimum width of 210 280 (MM) greatly reduces the waste of printing consumables, and better reflects the superiority of the saving of printing materials for small printing presses. . The optional control of the CP window plays an important role in the control of the printing state, because the fault detection system can prompt the fault to remind the operator to ask the electrical engineer for assistance. The general glitches can be resolved according to the pre-existing automatic correction of the CP window (such as insurance, leakage protection, etc.).
The above three points are far from enough to explain the advantages of Heidelberg's MOV-H offset press. Through nearly 13 years of use, its excellent cost-effectiveness is enough to convince any operating users. The amount of 140 million printed sheets seems to be a better indication that this is a high performance. Minicomputer. Like MO, this type of printer uses a five-roller linkage type water supply mechanism, which is extremely sensitive to changes in the amount of water, and can easily cause ink emulsification if the water temperature is too high. Causes the printing product to dry and slow down, has low glossiness, etc. We found that the refrigerating mechanism of the constant-temperature water tank was unsatisfactory in cooling due to excessive debris on the surface of the condenser heat sink. In fact, we generally do not pay much attention to this phenomenon, but we found through the inspection that the printing press is a whole, auxiliary equipment. Maintenance is just as important. We have modified the wetting system of the large CP2000 according to the revelation. A series of cooling water tanks are connected to the outside of the machine to ensure the constant temperature of the large circuit water system. Now we basically control the water temperature to around 9Co, because the constant low temperature is conducive to take away some of the heat generated by the operation of the machine, while taking away some of the water, which helps to reduce the ink emulsification.
Through summing up, we also found some problems, such as water roller scratches, drip water drop phenomenon caused by improper use during normal use, and uncontrollable water volume at both ends of the large-format printing plate. Solution Scratch phenomenon The ink residue falls into the water fountain roller due to the lack of timely cleaning of the ink. The water fountain roller is easily scratched under the action of the rotating pressure. The phenomenon that the surface of the ink roller is clean does not occur. Like the phenomenon of throwing water is generally due to the version of the lining paper, if the fountain solution is too much there will be infiltration phenomenon, the shedding part will adhere to the surface of the plate cylinder, then the PS version will gradually form a protruding package, often used by Both ends of the water roller wear faster, so that printing a large print size will have a certain impact, so the choice of lining polyester or white film base is better, but also at any time to pay attention to cleaning the surface of the roller surface dirt and water by glue When the pressure is adjusted, pay attention to the consistency of the pressure at both ends. If the pressure is too long, the surface of the rubber roller will be damaged. If the pressure is too long, the amount of water cannot be controlled.
The above problems can be avoided if we take a little care in our work. If the bucket is regularly cleaned, it is found that the foreign matter in the bucket is removed at any time. When cleaning the rubber roller everyday, clean up the ink on the clamp. If you do not clean the hard ink block on the clamp for a long time, it will damage the rubber roller during the operation of the machine. Keep good operation skills for these minor faults. I think Will be solved.
Compared with large printing presses, small presses only differ in appearance size, and maintenance, maintenance, and overhauling also require careful and careful attention. For example, air compressors, vacuum pumps, oil pumps, and refrigeration are less sensitive to the quality of printed products because of their low power law. They inadvertently increase the total failure rate of the machine, such as the aging of water pipes and air pipes. Operation affects. The MO offset press is a small sheet-fed press and a practical model. Its strong printability is also very competitive for today's printing market.
