We print a lot of poly garments.
I have setting in my dryer for wicking , dry fit and poly with spandex.
Most of the time the spandex is about 6%.
On our last run it was 10% spandex. So we added streach additive to the ink.
I slowed down the belt a bit to help with the extra 4% of spandex.
Did I need to slow down the belt or use it at the same speed as the 6%??
I did not have an extra garment to use the donut probe on.
Thanks
