Debate: Is a 50% polyester shirt actually better for sublimation than a 100% polyester one?

So I had a guy at a print shop in Denver tell me last month that 50/50 poly cotton blends look way sharper than full poly for dye sub. Said the colors pop more and don't bleed. I tried it on a batch of 20 shirts and the colors looked dull and washed out compared to 100% poly. Now I'm wondering if I messed up the heat press settings or if he was just wrong. Who's had better luck with blends vs full poly? What temps and times you using?

Lisa is probably onto something there. I run my 50/50 blends at 400 for 45 seconds and they come out great, but dropping that temp at all makes them look muddy. Your full poly shirts only needing 385 makes sense since the ink bonds way easier to that high plastic content.

Are you sure you pressed it hot enough? Ngl I've had blends turn out like trash unless I crank the temp up to 400 and give it an extra 10 seconds, but full poly works fine at 385.
