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, and then choose 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 the connection, the control of the main drive motor by the motor via a belt drive, gear drive, chain drive driven machine, it control the running of the whole machine. In the mechanical adjustment, inspection, installation and removal PS plate and blanket, clean the machine Dongguan monochrome printing brochures, you need to manually point the way to control the machine forward and reverse drive 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 high speed production printing brochures, 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 Dongguan folding brochures printed, each part of a coordinated action accordingly, as from pressure, water from the ink, 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 Dongguan color page printing brochures, as long as these switching operation, no matter what state the machine, must immediately stop the whole machine the emergency brake .

If the colors pink and blue with a 1: 3 mixed with tone, available blue and purple; terms of 3: 1 mixing to obtain approximate Qinglian color; undone color is derived from the three primary colors of ink mixed deployment. If they were mixing in different proportions, you can get many types of complex color. Eg: colors pink, yellow and blue with the same amount of adjustment, obtained almost black; pink and yellow and blue 2 parts in 1 were mixed formulations available brownish red; pink and yellow and blue 4 parts of the 1 deployment, available red brown phase; if pink, yellow each 1, blue 2 parts, can be equipped with an olive tone; pink and yellow of the 1, 4 were mixed with blue tone, available single room green hue, and so on.
