Over/ Under Cure?

[2020 Print]

Afternoon all,

Just had a customer send a picture of T-shirt we had printed for them where the logo has washed off. Am I correct in assuming this was under cured?

Let me know your thoughts on this!

Thanks again,
Matt

Under cured would be the correct answer

How do you monitor your cure temps 2020?

Are dryer and flash units have the temperature displays, additionally, we have a temp gun to make sure are dryer and flash units are showing the correct temperature.

When I use a temp gun (non-contact thermometer), to check cures from 280-310, depending on garment and ink, it reads from 370 to sometimes almost 400 for a split second just before exiting.

Non-contact temperature guns only read the surface temperature. If you're "shooting" it and only reading 350 or less, you can be certain you aren't getting a complete cure.  Someone a while ago posted the hiarchy of cure testing tools from paper thermometers to donut probes, but in many cases a good old fashion stretch test on the first couple test prints will give you a confident idea of whether you're curing or not.

Also just to add , it makes a difference if you have gas or electric. I've seen some electric dryers that need to be set at a much higher temp then a gas dryer . They're two different methods of curing a shirt. Also check your belt speed ,it's probably to fast .But like someone else said the stretch test is the best way to make sure it's cured .

Hi 2020, looks under cured to me, but there are a lot of possible causes to get this problem,a tip is you should check your dryer temp before you run your production, just  print a rag with your design and trow it to the dryer, the stretch test is a good indicator, sometimes we start the dryer and we believe it has reached the right temp, but reality its not.
