2880 for Dye Sub?
If you just have pigment inks in the 2880 they do sell papers to transfer to a cotton shirt.
It is not the same as the dye sub on polyester that your printing company will no doubt use.
Not sure what you are trying to do but if you do not have a dye sub printer and heat press I would leave the whole process to them.
I would call Conde Systems as they can suggest the proper paper that you can purchase from them.
Maybe a little more info?
