Hello, I'm new, and Ive read everything I can find, but cannot fins a solution. I've done all my pretreat testing, but for some reason, on darker colored shirts with a white underbase the black ink starts to wash out after the first wash test (all other colors are fine). The other colors are fine, its just the black ink that's washing out.

The ink is more than a year from its expiration. If I cure the shirt with light pressure the black ink gets chalky and I can wipe some of it off with my hand (looks like toner on my hand). If I apply a medium amount of pressure the ink seems to "stick" better, isn't chalky, and seems to wash a lot better. Is there a problem with my black ink, or do I really need to cure with medium/heavy pressure?

(Using Image armor pretreat, Lawson XL zoon set to 10, 340 degree cure on a GeoKnight press ar 1:30 to 2:00 min, new Epson ink from Equipment Zone (I had to order new ink as my starter carts were expired from lack of use, and were never installed).


Any help would be appreciated.

Anytime you pretreat a tee and there is some black ink in your design there MUST be at least 50% white under the black print. Be sure to use the Dark Colored tab (or the first option, Knockout black, for black tees) when printing in this manner.

Thank you Gator, But I may not have made myself clear enough. If I print a variety of colors on a pretreated shirt, then wash test it, the a large portion of the black ink washes off of the white underbase, but the other colors hold up just fine. I'm just having a problem with the black ink whenever its printed on a dark colored shirt (like a maroon) atop a white underbase, but only the black ink (other printed colors are fine).

Even if I run the heat press at 340 degrees medium pressure for 2:45 minutes I still get the black washing out in my wash tests (at least half of the density anyway). Even after 2:45 minutes the black ink feels a little tacky/sooty, and if I rub my finger across the print, I get some black on my finger (like carbon paper / dry toner). Anyone else experiencing this issue? Bad ink, maybe ???

Watch your printer while it is printing and make sure that it is indeed printing enough white under your black. Other than that you got me. That’s the only thing I can think of since your other colors are not affected. I highly doubt you have defective black ink but you never know.

Bad ink... There is not enough binder in it.
When you press it harder, the pigment is pushed more into the binder of the underbase, and this is why it gets a bit better.
