180-230 seems high for a basic underbase. I'd go 110-156. I print 100% poly almost every day. Just did navy on wednesday, came out great.
my thoughts exactly... we do a bunch for baseball jerseys and have had no problems
Let me ask you this. Why are you using a 110? If you can get a better print using a higher mesh screen why wouldn't you? Why not go after the thinnest deposit while still getting the same opacity?
I know there is no issues with fibrillation, but you are fighting the dye migration. We use One Stroke poly white with 110 screens because it gives us practically zero dye migration. Yes, the deposit is heavy, but we're doing sports uniforms, not slim fit shirts for a clothing line or retail store. If we were just doing light color shirts, then yes, we would print through a higher mesh. It's been my experience that people complain more about discolored prints over heavy prints, in the team uniform biz, that is. Just my 2 cents. Over the years I've gotten pretty good at getting next to no dye migration on the worst type of red poly bleeders.
