Hi David, welcome to the forum. You have come to the right place to look for information. An easy way is to type in the kind of printing you are learning up in the search box, such as screen printing, heat transfers, vinyl transfers, DTG (direct to garment), sublimation, etc and start reading. Youtube has some really good instructional videos that do a good job of explaining it all too. If you have questions, don't hesitate to ask.
