Do you also heat press t-shirts? Help me out

[Letticia Freitas]

Sooo, I have been using pixelmator pro to print tshirts with my designs.
I used a heat press and everything seemed like it went well. I even washed this shirt and the design came out intact.
Except for this stain, I have no idea how it got like that. I figured that if it was because of water, washing the tee would eff it up, but it didn't.
I think this happened after I washed my face while wearing it and some water fell on top of the design and maybe I should've wiped it off immediately??? idk...
So is there a way to fix or at least prevent this from happening?
Is there something i can press on top of my design to make sure it's "sealed"?
thank you

I have no suggestions so the following is pretty useless but it's very cool to see Pixelmator Pro being used for stuff like this, seriously!

I'd go over the quick press for a heat press. It takes full pressure to make clothes with vinyl to make it stick and remain . In my view, you can just get the pressure the consumer puts on with the simple click at topvinylcutters.com, it is just a big hammer. I'd go for a minimum swing away heat press of 15'
