    Hello friends
    Please have a question about white ink
    One minute After printing white ink
    his intensity disappears and begins to perceive
    What kind of regulation I have to make on the printer
    and automatically fill the head with white ink
    and increase the cycle of print
    The printer is Chinese
    Two Epson DX7 printheads are installed
    I attach a picture of my Configuration Set
    Please if anyone is familiar with these settings help me
    My supplier has not responded for three weeks
    I have no other alternative
    Thanks in advance
    Best Regards
    Kosyo

    I highlighted your issue. You need to buy a machine that works properly and is serviceable.

    Are you making sure to shake the ink cartridge well before printing?

    Agitating white ink is a daily requirement or it will settle in the bag and lines.
    Some printers can auto agitate the lines, but the bag is usually always manual.

    Not sure I understand your English but sounds like you might need to increase the white passes if your white ink is fading. My printer has 4 white ink lines/nozzles on a DX5 printhead (CMYKWWWW) but I still need to do 2-4 layers to get a good white color.

    Thanks
    Every day before I release the printer
    I mix white ink for 3-4 minutes
    use an electric mixer
    Can the problem be in a small amount
    of pre-treatment

    Regards

    Thank you
    I understood you
    But I do not know how to automatically run the white ink twice
    before CMYK printing begins
    Good luck

    I select multiple white passes in my software settings. Look at your software you might find something. At the very least you should be able to print at a higher dpi. Look out for options such as number of passes, double print, or ink layers. If nothing, then you can just try to print only white first, reload material and print white and cmyk over but this method will require amazing registration on your end.

    Thanks for the complete answer
    I give the printer 12 passes
    The problem is that the first 5 centimeters of the image
    are printed with very nice white.
    the next head of the print head
    the white ink begins to fade and perceive
    So the white becomes gray.
    I think the printer should have a feature for
    forced filling of the print head during printing
    For example, I want to set an ink-filled action on the print head in 3 minutes
    Thus, the printer stops alone, it goes to the station filled with the filling function and continues where it stopped.
    I ask myself a question
    Why CMYK prints without filling
    and the white ink does not.
    Not the print heads are the same
    If I turned them, they should work the same way
    The intensity of whites decreases progressively during printing
    This is a problem I do not know how to solve it
    That's why I ask and seek help from people with more experience
    Thanks in advance
    Good luck

    This sounds like the ink is clogging the nozzles. Maybe try a better quality white ink.

    Thanks for the answer
    I noticed there was a problem with the whiteness of some nozzles
    What the FLASH function should mean in the printer menu
    An elementary and safe way to clean the nozzles
    Good luck
