Therefore, screen printing machine in addition to the squeegee scraper must also configure an ink will be returned to the squeegee scraper the ink Zaigua of the end of the squeegee to the screen printing plate and sent back. In addition to sending the ink to send ink scraper, but also play to block the graphic part of the mesh with ink in order to avoid drying ink of net hole, while under the influence of time (Zhang) printing. Send ink scraper for aluminum products or metal products. Squeegee by hand, only use a squeegee scraper, printing and ink return are the only scraper. The customer just needs to wait until cell phone signal booster cools down. Before printing to make preparations? Do preparatory work before the printing is to ensure that a work of printing the smooth conduct of essential. Following preparatory work should be done before the printing production. ① clean up the printing site, to ensure that certain operating space around the printing units or printing press, avoiding other objects hinder the work. Keep the venue clean, to avoid dust and other print quality. (2) to adjust the humidity and temperature of the printing shop to meet the printing requirements. ③ to prepare a good fit of the scraper, and check whether the scraper bumps, if there are bumps to ground to prevent scratching the plates affect the printing quality. Theoretically using a Coiler TG900 27dBm cell extender with 60dB gain and selected antennas a site with -90dBm can be amplified to -27dBm which will provide coverage to a normal sized home. Between 7~10met radius on the GSM900 frequency is common. Much larger coverage arias have been achieved regularly but one tends to be very careful in sketching coverage when RF is being applied as it is not very predictable and so many variations apply.Production plus the net leakage Printing Screen Stretching angle should be how to control? Such as the production of red, blue, yellow, black, four chromatic plus screen, stretching angle can be 0 degrees, 4 degrees, 0 degrees, 12 degrees. Screening screen printing, how to prevent moire generation? We must first select woven uniform mesh, some visual uneven mesh can not be used for the screening plate, another plate angle stretching, generally does not produce moire. Screen lines decided, the corresponding number of the wire mesh? General screen mesh for more than 3.5 times the number of lines, not more than six times. Such as the number of lines to 80 lines minimum mesh: 80 * 3.5 = 280 mesh. With a photographic film thickness between the lines too much, how to select the proofing time? cell phone signal booster can protect the confidentiality of the meeting.
