dry mount press

Does dry mount presses have heat on both surfaces or only one of them?

I ask because I have the chance to buy a t-shirt press wich has heat on one side. Looks like a good and cheap option for dry mounting press since it has temperature and time control.

Usually just the top side is heated.

Thanks. Then I guess the t-shirt press will do the job.

And when not mounting prints you can start a side business!
