I haven't used the Inktra (Stahl's I believe). Not sure if it was their take on IronAll for darks, but IronAll for darks is another good brand.
...I have a "sample pack" of the SHAHLS "INKTRA OPAQUE" here in my hand....
On the back it's TRUE name is......
"Jet Opaque II" manufactured by Neenah.
(orange lines or an orange grid)
I buy mine from Tshirtsupplies.com(
"JetWear Dark") and get a great price.
It has never "bled" on me and presses great.
.....but remember.... there are always "different" batches out there!
When I purchase
any pack HT paper I take a sheet from the top and a sheet from the middle (towards the bottom) and "test" it.
Then I know whether to keep it or send it back for an exchange.
