Light paper features the following aspects: 1. Light thick and light. The bulk light paper is very good, so this may be the same thickness of paper to replace the original high quantity of paper, thus saving shipping costs and postage costs. 2. natural color. Light paper made from chemical pulp, without optical brighteners, by the addition of a special dye creamy white or pale beige, compared to conventional coated paper, offset paper, light paper color darker colors and wood pulp close . Giving a rustic, natural feel, long time to read with light paper printed books will not cause visual fatigue. 3. Paper surface smooth and delicate. Touch light paper papery feel its soft and delicate, because there is no coating or coating amount is low, so that the light reflectance of the paper and the ink is not high, but a strong absorption capacity. 4. Long life and environmentally friendly paper. Light paper is chlorine-free paper grades, 100% pure chemical pulp papermaking, non-fluorescent brighteners and other ingredients, so that the paper was slightly alkaline, you can save thousands without deterioration. Lightweight uncoated paper processing, mainly by fiber, calcium carbonate and water, do not pollute the environment, printing brochures, is a green product. Laser printers method of charging the photosensitive drum, specific charging methods vary by model and uses are also different, but the charge basically the same principle, and are based on DC high voltage corona discharge for charging the drum surface. In the charging process, the photosensitive drum adsorption charged toner, is most likely the first part of the environmental impact of building the stage. In this session, if you are using a compatible consumables, or filling toner, it can easily cause carbon adsorption process as going into the atmosphere, and this release is a very small toner particles Such particles can be accompanied by our breathing into the lungs, the long run is bound to impact on our health. The developing process of the photosensitive drum when the electrostatic latent image formed on the surface, the toner image after developing shows, this process is "developing." Development work done by the developer, whose role is the electrostatic latent image into a visible image. When we print paper into the machine, the paper will be in contact with the photosensitive drum before, is full of negative charge. When the print paper in contact with the photosensitive drum, the electrostatic latent image with a positive charge and the printing paper will have a negative charge attract each other, thereby adhering to the print paper, thermal transfer unit after heating the toner particles to the paper outer fiber absorption, eventually forming the printing image. Finally, the printer will automatically remove the remaining toner on the photosensitive drum, and the potential of conversion, so that the next cycle begins. 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. Sheetfed offset press operation is so controlled by the main motor through belt drive, gear drive, chain drive driven machine, between the rollers, the tooth row, institutional cooperation and coordination by the mechanical action of connecting the product manual printing, drive motor to control the running of the whole machine. In the mechanical adjustment, inspection, installation and removal PS plate and blanket, clean the machine, you need to manually point the way to control the car forward and reverse Huang Jiang manual printing machine to operate, 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 can accelerate start feeding manual printing, 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.
