Process characteristics lithographic press operation control such that the drive inverter motor drive can well be applied to the printing press, to meet production requirements, we must first understand the characteristics of the press operation control technology, its inverter function of what made Requirements brochures printed, and then select what type of drive, and how to transform specific docking original line. Sheet-fed offset printing press is running between the rollers, the tooth row, institutional cooperation and coordination by the mechanical action of connecting Dongguan monochrome printing brochures, the control by the motor via a belt drive, gear drive, chain drive driven machine, main drive motor to control the operational state of the whole machine. In the mechanical adjustment, inspection, installation and removal PS plate and blanket, clean the machine when printing plant in Dongguan instructions, you need to manually point the car forward and reverse mode to control the machine operation, about 4r / min speed is appropriate. During the Shanghai printing pause, in order to ensure PS version is not damaged, the ink is not dry, to make the machine at the same speed of the long car running. When the machine starts formal print production, there is an initial speed of about 3000 rpm / hour. When the feeding machine feeding can begin to accelerate the machine at a higher speed production, generally from 6000 to 8000 rev / hour. In order to meet the requirements of different production speeds, via a speed potentiometer for speed adjustment, the actual value of the speed can be indicated by the speedometer. Down from a high initial printing speed of printing, there are two cases. First, the manual button slow down, the other is the printing process paper fault is detected, such as crooked sheets, no paper, double sheet, etc. so that automatic press deceleration, the parts to be made accordingly coordinated action, such as from pressure, water , from Mexico, stop feeding and so on. At the end of production, stop button is pressed, the machine accordingly to free stop mode is smoothly stopped. In addition, in order to ensure personal safety, dangerous parts press fitted with safety switch or emergency stop button, as long as these switching operation, no matter what state the machine, must immediately stop the whole machine emergency brake. Printing in the final analysis is a replication technology to copy graphic images to make the above substrates. Traditional printing technology is divided into convex, flat, concave, missing four ways, a common feature of the four printing plates is achieved through graphic image replication. Among them, in addition to screen printing were missing the most commonly used surface printing can be achieved, the other can only be printed in several printing medium on a plane. Inkjet printing technology is different. Like other digital printing technology, inkjet printing technology is not printing. Graphic inkjet printing technology is to be replicated printing directly on the substrate, if handled properly, even the curved object, you can achieve a good image quality. In reality, people use inkjet printing technology, not only the surface of the printed surface of the object, and has achieved a print on irregular surfaces. At the same time, with the advent of UV ink technology, many of the original can not be printed dielectric materials, can now be printed using inkjet technology. Inkjet printing has greatly expanded the range of printing materials and surface morphology can be printed, which undoubtedly can cover a wider field of printing objects that can be served is broader. Color printing in a production situation will always be color printing, and is difficult to completely eradicate a fault, according to the chefs explain and personal summary, has the following approach: If the ink path, no problems, you should check whether the rubber gasket is standard folding brochures printed in Dongguan, the proposed liner thickness should be] 35 wire, blankets best brands with aluminum strips and blankets are the new best. The new blanket in use for some time the best re-tighten again. If these are done after heat discoloration problem is still not resolved, then you may want to consider the problems of the teeth, dental pad dental piece should be cleaned, but it is best to take off spring cleaning. Check the paper the case of paper, including paper wind under the regulation, the paper flatness between conventional, paper and paper pressed forward with, the operation of feeding the belt and so on. After you have done these you can try to print, and in proofing the best choice when better coated paper proofing, to avoid affecting the paper problem. For tissue on the impression of wind to try to open a small, open big for Thick moderation. After doing these color prints may be able to solve the problem, of course, there can not be resolved, if these efforts are still printed color Heidelberg notice for repair as soon as possible. Let the problem quickly resolved. Dongguan product brochures printed brochures printed _ _ manual printing by the Dongguan City, often beyond packaging products factory provided.
