Weird texture from heat pressing - temperature problem?

So, I'm getting an almost almost alligator skin texture when I heat press my polyester fabric. (I'm a total noob, but I did read the faq thread and goodled and am still unclear.)

I *think* its the temperature, but this is happening at 360 degrees... can I safely go any lower with sublimation? Is there something else it is likely to be?


(The pattern tends to only happen from the mid-point forward on my heat press, and the back part of it is colder then the front, according to my laser thermometer)
