The temperature and time settings for your mug press will depend on a couple of different things. Each machine will use different amounts of pressure and heat, and will also require different time settings. It is best to read through the user manual for your new press to find what the manufacturer recommends. Something else that will come into play is the material that you are transferring onto. T-shirts will need more time but less heat than a mug, so make sure you read through what works best for your press in these instances.
