Hello everybody,
First, sorry for my english !

I have printed 300 black t-shirt 100 % coton with two colors.
Yellow et white qcm ink.

I have a problem that i had never seen during 16 years : after washing there is yellow clouds on the white !

The yellow ink is still on shirt, no problem but a kind of migration of the yellow pigment.

I really don't understand !
If someone can tell me what i can do : second pass in the oven ? a little heat press ? (we have tried 3 washing machines with différent powder...)

Thanks a lot

I have seen this happen to me, on shirt that I have bought to wear myself. The most recent, a black shirt with white and orange spot colors. After several times wearing it, and washing it and drying, the white will get a cloudy yellow tint to it. But, after another wash, it will go away. Then, after several washes, it will come back. So, I really don't know what causes this. Maybe the soap being used. Or, too much time in the dryer, mixing with other colors. Who knows?
