Discuss the various aspects of heat press technology. Transfer paper, inks, plastisol transfers, vinyl cutters, printers, commercial usage, durability, suppliers, etc.
What do you mean by "full process"? Do you want to know the details of how they physically go about printing them? The process of how a design is chosen, how it is distributed to the customer, etc.? Or...?
You should go research companies like....X-it, Wildside, Ace tansfers, Pro-World, Impulse, Springhill, Fand R, Global, Dowling etc and see what the actual transfer makers do. The basic process is screen- printing on a release paper although there are several variations in the types of transfers made.
Look over the threads in this site and also the screenprinters site.
