Is this flash dryer going to be for running a printing business or a hobby? If your using a flash for curing your shirt you have to remember this will take longer then using a conveyor and depending on the size of the print, if your design is bigger than your flash then you will have to move it around to cover all areas. Also, remember flash dryers don't hold the same temperature all around. It will be hotter in the middle then on the putter portion and if for example you are using plastisol your printed portions must all reach a temperature of at least 320 degrees.
