Do I need a specialty press for any good that isn’t flat?
For the most part, yes. Hats, mugs, plates, anything that isn’t flat will most likely require a specialized press to take a sublimated print. If you're sublimating apparel, but also want to offer non-apparel accessories and add-ons, a combo heat press might be the best option. This type of press is usually a flat swing-away press that comes with attachments that will allow you to do mugs and other goods that aren’t flat. A standalone cap press will have a curved platen that allows you to sublimate caps faster and more easily. Mug presses are generally adjustable and are designed to handle different sizes and shapes of mugs. If you’re planning to sublimate a lot of one particular item, investing in a specialty press can be a wise move.
