What should I keep in mind when decorating round objects with heat-applied graphics?

With all heat application, the most important considerations are time, temperature, and pressure. To get the right pressure, a smooth print surface is imperative. 

For some objects with rounded edges, you can position the item in a way that gives you a smooth surface for application. But when decorating fully round objects, like a ball, it may be worth investing in a heat press designed specifically for heat printing rounded items.
