has anyone printed on ribbed tank tops?

iam having problems and not sure what iam doing wrong

iam using white and also pink union ink on a black ribbed tank top
i also have added a stretch additive to my ink (10%) and it stills looks the same

thank you

Sorry for not seeing this earlier. What exactly is the problem that you are having? Adding stretch additive shouldn't alter the way the print looks. Is it still cracking when stretched? Is that what you mean? If so, try more additive. Adding more won't hurt but too much can lighten the color of the ink.

Upload a decent image of the printed shirt when relaxed and with the ink stretched.

Maybe we can help more.
