When the flexographic printing machine is printing, it is very important to follow the correct printing process, so what is the printing process of the flexographic printing machine?
Pay attention to the oil quantity and oil temperature when starting up, and do not start the machine at high speed without lubrication to avoid damage. When circumferential plate registration is required, start the circular plate adjustment motor to make the planetary wheel carrier revolve forward and reverse, so that the speed of the printing roller at the synchronous speed can be superimposed or superimposed, so as to complete the plate registration requirements in the circumferential direction.
The squeegee is used to ensure a uniform supply of ink to the printing plate. If the scraper is not used, the ink is transferred with the rubber roller, and the anilox roller is pressed tightly, the ink transfer is fast, and the speed is slow. The amount of ink carried by the anilox roller is very different, the amount of ink is more when the rotation is fast, and the amount of ink is less when the rotation is slow. For this purpose, a doctor blade is set up on the flexo press.
Anilox rollers are precise transfer rollers. The amount of ink transfer is determined by the number of mesh lines per inch. The higher the number of lines, the more mesh pits and the less the ink volume; the lower the number of mesh lines, the fewer mesh holes and the greater the ink volume. The number of screen lines of the anilox roller in printing is reasonable, which is determined by the color requirements of the printed product.
The synchronization of the power of the printing unit of the flexographic printing machine, the balance of the ink supply, and the balance of the printing plate roller have certain requirements in the printing process. The printing power of the letterpress printing machine is transmitted to the reduction box of each unit by the main motor, and each color group runs synchronously. To make the overprinting of the printed product stable, the gear box should be well maintained.
