    Default TW Graphics Screen Clogging.

    I am using TW Graphics 5000 series ink and have been having some major issues with the ink drying in my screens after basically one pass. Do I need to use some sort of additive mixed in to the ink to prevent it from drying so quickly?

    I am trying to print a fluorescent pink, so the mix I am using is:

    150 grams of 5000 series clear (75%)
    50 grams of 5000 series white (25%)
    +
    70 grams of fluorescent powder (35% of the above weight)
    10 grams of flattening powder (5% of the above weight)

    Any thoughts or recommendations would be extremely appreciated!

    Are you starting with a dry screen?
    Wet your stencil with a 50-50 mix of TW s34 screen cleaner & water, before adding ink.
    Other usual culprits...dull squeegee, slow human, bad flood or no flood...

    Search the forums for threads about printing with TW; there are many.

    I print with TW 5000/5500 every day and I never have any dry-in issues, at all. Never.
    So I have to assume that if you are having those problems, you are doing something wrong.
    TW makes a Retarder but I never find that I need it, even with very high-detail images.

    Thanks for the information crosshair. I did not wet my stencil, so this may be what my problem is. I will try this and let you know what happens. I have noticed that the ink dries on the paper almost instantly after I pull the squeegee, so I would be (pleasantly) surprised if this fixed my problem.

    Ok, so I ran a test with your suggestion (crosshair) and some other suggestions I found on another thread and I basically did two things differently. I added some water to thin the ink up a bit and I also used a 50/50 mix of water and 409 to pre moisten the screen. I sprayed the solution all over the screen and then I pulled a few test prints of it and then wiped the excess up with a paper towel.

    I then made some prints with the TW Ink mix I mentioned above (with the addition of a bit o water like I mentioned)(I was also sure to back flood nice and thick) and it was like a magic trick. Printed perfectly! Stoked to finish this run tomorrow with my newly acquired knowledge. I am really surprised that that little pre-moistening tip changed things so dramatically.

    That may be the issue, my screens have holes, not hols. Where can i get this other fancy hols mesh? Will it improve my image detail?
