I have a request for quite a few performance shirts that are 100% poly. Does anyone have experience running these with IA pretreat?

Yes, and others also.
not dark yet.
Cheers! Beers are on me always.

I have seen some AMAZING poly prints using Image Armor. I would contact Brian Walker on here and ask for his suggestion on how much and which formula to use for the best results.

I printed 100% poly white muscle compression shirts... 100 of them. Came out awesome... Washed absolutely perfect

What PT didi you use? Were you printing white ink?

 

[jmcgurren]

No.. White shirts I was saying. IA light. White ink doesn't work unless you print white, leave it for two days to dry, and then print the color layer.

Here are some notes on 100% poly printing:
First of all it is very easy to stain these shirts with yellowing from the pretreat. Precautions need to be taken to reduce this issue. First I am not using Kraft paper to cure ink or pretreat like I do with all other shirts. I use a finely textured Teflon sheet instead, but I am sure regular Teflon or parchment paper/quilon would be fine too. When curing inks I do two presses of 35 seconds. I press the first time, and then stack them in a pile to wait for their second press after all are done. Then at the end of printing I press them all again. This cool time seems to prevent yellowing. I am spraying these 100% poly A4 tees with IA light at 2.5 turns on the viper one.
The other thing I find necessary is to lower the ink % a little bit down to 85-90% or so. Reason being is that in high res mode at 100% it is actually bleeding through the back of the shirt a little bit. I can see a slight ghosting of my image on the back.
