Yes but its just annoying to sit there and do it though but yes that would work as long as you can see see count down on it you should be fine.

8 minutes is about what the black shirts are taking me to cure.

Epson ink is one of the quicker curing inks. the longest is old school Dupont which had like a 3-3.5 min cure time at 350F I have done shirts on settings a lot higher than you are using and still have it take no more than 80 seconds at 330F.

As to a forced air conveyor (which I have) it takes about 8 mins or so to cure it all depends on design I have cured things in under 5 mins on the dryer. 8 mins is kind of on the higher end of time for me. The water in the ink needs time to evaporate and cure the heat press does it so much quicker because it is direct heat resting on the ink the forced air takes longer. Inferred dryers take maybe a min or 2 longer and have a higher risk of scorching the shirt but do work. I started with a little red vastec dryer.

How long does it take in a forced air dryer? Do you have one that you recommend?

It does take longer to cure in a conveyor dryer usually around 6-8 mins depending on print however the idea is you can keep printing shirts and adding them to the belt and have a decent work flow.

6 to 8 minutes in dryer shouldn't take that long. Try using a forced air conveyor.

The black ink wipes right off on my finger. I have been contemplating a dryer but was told that it would take too long to cure in one.

If the heat plate is touching the fabric, it's enough. If this still doesn't work, you need to increase the amount of white ink in the print settings.

Yeah, its hard to guess what the issue is from just a description, and I'm getting rusty at it as well. Last time I printed white DTG was over a year ago.
