Would i be rite in thinking once my plastisol ink reaches the correct temp to cure 280 to 320 i take it off the flash dryer and stretch test, done. Is there a time limit or can i take it off as soon as it reaches it no matter how long it takes even 20 to 30 seconds. I have a ceramic curer heats up realy quick
if it is a real thick print like a white you can leave it in for a little longer to ensure that the heat travels all the way through.
i am assuming you flash dryer

Yes i have an idustrial curer not a cheap thing off ebay can i take it of as soon as it reaches core temperature even if it only takes 20 seconds to reach it, or should i leave it under longer.
Careful with the temp gun that you only measure the ink and not the surrounding shirt temperature too. But if the stretch test is cool, then you should be alright.
I would like to caution two things! First, plastisol ink is not recommend to cure under a flash unit. It is recommended to be cured through a belt dryer, either gas or electric. The entire ink film needs to reach the recommended cure temperature and this is hard to do with a flash unit without scorching or slightly over curing the top layer of ink film.
Also, A temperature gun is only reading the temperature from the top layer of ink film. So you do not know what temperature the entire ink film is reaching.
I just want to caution, as you can undercure and then having cracking and wash out.
I don't have a conveyor dryer i have a 20" X 14" flash dryer do most guy have the money for a conveyor on here as they cost a bomb would using my 80cm X 32cm heat press be better than using the flash
I cannot tell you if most people on this forum have a conveyor dryer, but I can tell you that the top performing shops and shops that grow tend to have a conveyor dryer. I understand the concern of price, but it is the suggested curing for plastisol inks.
I am not sure which is a better curing option, the heat press or the flash unit. If you try to cure with the heat press, you would need to flash the ink until at least gelled and then put under the heat press with a piece of teflon. This would cause the ink to appear really smooth and at times shiney. This may or may not please your customer. Just something to think about.
heat gun
