1. Can you send a piece of fabric for test printing ?
Yes we are happy to supply 1 piece white fabric.
2. I'm having trouble with the images ghosting/slipping after printed. How can we solve it ?
The fabric will thrink a bit in the 1st heat press process. So just have the bag heat pressed without any picture the 1st time. And then print images.
3. The white fabric get a bit yellow once heat pressed, how can we solve it.
It may happens if the heat tempreture is much high or you press it much longer. Just adjust the tempreture and pressing time. We always use 220℃ and 30 seconds for sublimation.
