I would spend the extra $100 and get one from a reputable supply co. I have had the basic one from here Screen Printing Flash Dryers, flash dryer, spot dryer, screen printing spot dryer, screen printing dryer for 2 years and it works great.
In between colors you don't actually "cure", you just dry the ink enough to apply the new color, either over it, or on the side. If the previous color isn't dry enough when it touches the underside of the screen it will create a little nasty mess.Hey,
Also is there a difference b/t curing between colors and a final cure? Do you heat them differently?
Thanks
