    JM-EM5060  Vacuum Exposure Unit


    The plate printing machine is a contact exposure imaging device used to make printing plates. It uses pressure (including atmospheric pressure and mechanical pressure) to make the original plate and the photosensitive plate closely fit, so that the image on the original plate can be accurately exposed through photochemical reaction. Made on a photosensitive plate. The printing machine is mainly composed of light source device, exposure chamber, vacuum chamber, electrical parts, machine base and other parts.

    1. Choose high quality metal halid lamp. keep long life.

    2. Reflect cover made by resist aging materials.

    3.It can reach the vacuum state instantly, and save time for printing

    4. Exposal time auto adjustment and controlling.

    5. High vacuum degree, easy to transfer and copy fine lines

    6. Automatic door of  lamp shut off and turn on when exposure and finish ensure long life of  lamp

    7. High toughness Rubber Layer ensure Film closely cover with frame

    8. We also can supply the different size of screen printing machine according to customer’s requirement



    1. Long time will not work, pull the plug.

    2. Finished working after a version, according to the stipulation time open and close.

    3. If screen frame with water, don’t use vacuum, otherwise the inhaled water will be rusted the vacuum pump.

    4. Keep the worktable neat and dry, with soft and delicate cloth to clean after finishing work.

    5. Keep in ventilated and dry place, far away corrosion items.

    6. Do not keep it in high heat and humidity place.

    7. Once turn off the lights, should be in a given time after 5 minutes (that is after cooling tube) to turn on the light, otherwise, it will reduce the working time of lamp.

    8. light hand should press 1 second, don’t long hold, it’s too easy to burn out trigger


    Working Principle

    Screen printing screens are coated with a light sensitive emulsion using a scoop coater. When the emulsion is dry, place a positive print of your image on the screen. Once you burn the screen, the emulsion that did not get any UV will wash out of the screen exposing the tiny pin holes. The surrounding areas that were exposed to UV will be cured. Hence the ink will pass through screen onto your substrate.


    Main Features

    1. Rational design & easy operation: based on humanity and practicality principles, with the elaborate designed table type structure, it’s much easier for screen exposure with high precision.

    2.Independement settings of vacuum and exposure time with automatic memory function: The vacuum time and exposure time can be set up separately just according to actual requirements (setting ranges: 0-999 seconds); When exposure is finished, the power supply of the lamp will be automatically cut off, it will deflate and beep by itself, then please turn it off. When you need exposure again, just connect the power supply, then it will work automatically according to your former settings because of its automatic memory function.

    3.Oilless vacuum pump with high quality is durable with no need for oil injection.
    4. 8 pieces of special UV exposure lamps will guarantee a precise and even exposure effect.
    5. The high strength toughened glass (thickness: 0.24”/6mm) is with high press resistance and not easily scratched. Besides, once broken, it will turn into pieces without sharp edges to avoid user’s injury.
    6.All-metal construction & elegant appearance with advanced electrostatic paintings, easy to clean and no rust.
    7.Excellent packing in study wooden case as a whole will guarantee a easy and safety transportation.


    Choice of environment

    Due to the particularity of the plate-making process, the plate-making environment has relatively high requirements, and the plate-making workshop is required to be well sealed to avoid direct exposure to strong light. In this way, it can play the role of dustproof, and secondly, it can avoid exposure and light leakage during the storage of PS version or the process of printing. If there is a lot of dust in the air during the printing process, the larger particles of dust may fall on the surface of the PS plate or adhere to the surface of the film due to the electrostatic adsorption of the film. It will directly affect the tightness of the PS plate and the film. After development, it can be observed that the PS plate exposed to the sun is partially vacant or grainy and dirty, which affects the reproduction of the original screen line density. It can be seen that the sanitation of the environment has a great influence on plate making, especially color plate making.
