if i printed on some transfer paper using my sublim printer would i be able to heat press this onto a cotten tshirt

or would i need to buy sublim tshirts

Im unsure about this - as i remember yrs ago could print on a tranfer and iron it onto any shirt

I don't know if I can answer, but:

1. if you want to sublimate, you have to use sublimation tshirt (some cotton inside, polyester outside), or polyester t-shirt
2. if you want to put transfer using transfer paper, you can use sublimation ink (but preferable is pigment ink - a) cheaper, b) better wash results)

-------------------------
1. your image (design) will be part of the t-shirt
2. your image (design) will be on top of your t-shirt

I hope, it is right and understandable...

at least you called them T-shirts and not tank tops or something rofl

Steve for God sake!!! I just sprayed my drink all over my phone lol !!!

cardman, you will be pressing the t shirt transfer onto the t shirt, and the transfer stays, it does not peel off to leave the image, the image is on the sheet, and the sheet is adhesive. i would think using sublimination inks you will not get the same colour, you really need pigment ink

and smitch - you beat me to it tank top pmsl
