Get onto your knees and watch for the smoke. The smoke is a signal which indicated when the ink is hot enough to smoke, which "coincidentally" is the same temperature needed to cure.
I have a 4 foot dryer, the first 3 feet have heating elements and the 4th is blank. Looking into my dryer, the shirt needs to be smoking during the 3rd heating chamber. If there is smoke on the first, the dryer is too hot. Considerable smoking at the second is still hotter than needed. If its smoking before the forth, it is too late.
On my dryer, the shirt is already cooling in the 4th foot, so it is all but finished smoking when it comes out of the dryer. The dryer exhaust contains the vast majority of the smoke. For dryers without a cooldown section, i'd have the shirts come out smoking.
heat can be controlled either by dryer temperature or speed. If the smoke is hitting too early, you can either turn up the speed to increase production or turn down the dryer temperature to save energy costs.
My dryer is a brown, which come with (pc style) cooling fans on the exit path of the dryer. We use a pole fan following the flash dryer.
The issue might just be you have sensitive hands. They make cooking gloves which allow working at oven temperatures. There is no shame in using the protective equipment. The shirts coming out of the dryer will be hot.
The cool new Chef's Planet Oven Glove is a heat and flame resistant five-fingered glove that makes it much easier to grip and handle pans going in and out of the oven, compared to a traditional oven mitt. This seamless glove features a DuPont Nomex outer lining that can withstand temperatures up to 500? F (260? C), has a comfortable double knit cotton inner lining and fits great on both righties and lefties. Best of all, they kind of look like big old cartoon gloves!
