Phillip Newell of Newell Graphics, Iowa, USA recently sent through some useful technical tips for working with Permaset - many thanks Phillip. See below for Phillip's comments...

Curing is one thing I had a little issue with when I first got started with Permaset. I use a small electric dryer that is 8' in length and has a 4' chamber. What I realized is you have to slow the belt down enough so that the shirt remains in the chamber for 45-60 seconds. I also turn the heat up a little higher when printing on darks so that the shirts are hitting 375-390 as they exit the tunnel. Since I've adjusted this, I don't have any problems with the images washing out. Of course light garments have a much thinner ink deposit, and so require a little less time and temp.

The other key is air circulation. Once the moisture escapes from the ink, it needs somewhere to go. Otherwise is just sits in the dryer and impedes the drying of the other shirts. Fortunately, my dryer (Lawson Encore) came with a forced air option. I also added another inline duct fan (about $40) to the exhaust stack as it exits the building to help draw the moist air out of the dryer.
