The ink does matter...I got an Epson printer for that reason...the ink I have is Claria, but I think there is even one better that this. Also...you should let the printed item set for 24-48 hours and then I use Snuggle fabric softener...HAS TO BY SNUGGLE. 1/4 c in 1 c water. Holding 2 corners...drag the print through the mixture and then lay on towel and roll up to get out excess. Then you are supposed to use a hair dryer to quickly dry it....I actually don't do this and it comes out fine.
All printeble sheets don't act the same etiher. Hope this helps.
