Roland used to make a fabulous 100% paper backed Poly fabric that was definitely printable. The only downside was that the edges needed to be sewn and you had to double print to get a more vibrant color reproduction. I haven’t seen the product for years....... Irv, I think I gave you what I had left??? I can’t even remember the name of the stuff.
LOL, I will have to look through the stuff, which I have some left and others made me tons of money. I think I owe your machine a visit - lol.
There is a company in VA that makes printable fabric - issue not cotton. All fabric has to be treated or the ink is absorbed. The main reason I got into polyester - to print on fabric.
