Title: Identify probable failure from a picture?
Post by: Stinkhorn Press on December 15, 2016, 03:02:53 PM

this has happened, what 3 times in the last year (this bad).

always white. 2 times of the 3 had a color overtop.

not a big deal to replace, all luckily on small runs.

up until July we were running a small electric dryer. Now big and gas. the cure is waaaaaaay better now. i THINK these were all cured in the old tiny crap dryer. my guess is CURE issue.

ink - for white either wilflex sprint or quick white OR synergy poly white.
top color is wilflex epic line

yup, cure issue.  More than likely undercure.

I have also had it happen due to over flashing. once over flashed recuring wont solve the problem either. Thats how i realized it was over flashing

usually overflashing would make the top ink not stick as well, these are coming off together, so I would doubt it's that.  could be though.

over flash is my guess as well.

overflash causes top color failure, but not the base white to crack like this.  Definitely undercured.

Undercure and the shirt was not laid flat.
