Sorry, I did not print any large transfers with this paper. I did however complete my wash test on the shirt pictured in this thread. It has gone through 12 wash cycles since the original post on 11-23-2009. All wash tests were done with no bleach, mostly shirt inside out, but some not, cold water wash and rinse, wash loads not separated by color, and dried on high heat, only because this is the way I wash all my clothes.
The shirt color has faded slightly as evidenced by photos. The graphic has held up amazingly well. No signs of color chipping, loss of adhesion, or shrinkage of transfer. I also did not have any problems with the graphic getting stiff or wrinkling in the drier. It still feels as pliable as the day it was 1st pressed. The image has only slightly dulled. I am quite surprised since this transfer was created with OEM Claria ink on my Epson 1400.
Overall I am very happy with the results I obtained with 3 G Jet Opaque transfer paper. I don't think I would use any opaque transfer paper to retail a t-shirt, but I will consider using this for other items.
