Flash cure for dryer question(s)

<< < (8/9) > >>

Frog:
fine except that "under the shirt" is not the same as "under the ink layer"

Gilligan:
*sigh* why do you guys have to make everything so complicated. ;) :p

So... are you saying that because it will take longer to heat up under the shirt or possibly under the shirt will reach that temp BEFORE under the ink?

Either way... if my ink cures at 300 what should I set the temp alarm for if I'm putting it under the shirt (essentially two layers of fabric).

Frog:
I'm saying that heat will most likely go through unprinted fabric faster and easier than through the same fabric with an ink layer, possibly a rather thick one from your p-f-p white.

I would love to say a reading of 310 would insure a cure but I'm not sticking my neck out with your set-up. It's just nothing like I have ever done.

Bottom line, wash a shirt three or four times to truly check cure.

As a quick check, you can check for some stretch without cracking.

Because everything is actually complicated?

If you want to get your setting dialed in, or at least as much as possible with your setup, get some temperature strips, place on on the shirt, and print over it, leaving the portion you read visible.  This will by far give you the most accurate reading.

And then, of course, you have to consider all the variables, such as garment color, ink color, drafts, etc, and compensate for those.

Gilligan:
But even if you print over the temp strips the part that you can read isn't what is covered in ink.  So that really wouldn't tell you what the bottom layer of ink is.

Great, now you guys have ME complicated the issue. :p
