Printing on T-shirts

[robotechnics]

Hi everyone, this is gonna be a strange question but here goes.

I only have ever pressed on 1 sided items like mugs and mouse mats.

If i wanted to do a T-shirt do i need to put something inside the T-shirt to stop it going through to the other side?

Will a Teflon sheet inside the T-shirt be enough?

Thanks For Your Help.

If you're dye subbing it's a good idea to put a sheet in between yes. If you put the shirt over the press rather than on it then put the sheet on the lower platen under the shirt.

I use greaseproof paper.
