- Why did the ink wash off those shirts you printed? There could be several reasons, but overcuring the ink is probably not one of them.
Rick and Mike Beckman, the inventor of high density ink, discuss how to test your prints and factors other than dryer temperature that can affect how the ink cures on a garment.

i guess the heat press method at 320F is best to make sure it is fully cured without doing a wash test. i would just flash dry it and place it on the heat press to cure and a lot of customers like the smooth feeling vs just conveyor drying imo. they sell dual pneumatic heat presses that allow you to just move the top heat platen from left to right and it automatically presses down which is cool af! i think this is a perfect addition for someone printing at home with only a 120v option since most of the good conveyor dryers are all 240v and way longer than 5ft.
AWSOME
I've got 99 problems, but overcuring isn't one of them.
Curing I think is all about the stretch test...if u can stretch your item without cracking showing up...then your item is good...
I was using a white fnink their instructions said I could cure at 260...only reason I like 260 is I was using polyester...at 260 I was getting cracking.......I had to bump heat up to 300...then I didn't get cracking and the polyester disnt migrate....
What makes it crack?
If you suspect the shirts have moisture could you run the blanks through the dryer prior to printing?
Yes, you can.
Not sure if you are able to but I’ve found that if you have enough heads and the finances that using a stampinator in head one, cooling in 2 and starting your first color in 3 greatly improves print quality as well as limiting moisture. I run 3 stampinators, head one, the base and a light stamp in the last head makes my designs look absolutely amazing as well as removes moisture.
Do you wash the shirts inside out or normal? Thanks
Either way. Doesn't matter.
is this for water base or plastisol?
This is for plastisol.
Keep an eye out for an article about the curing, overcuring and undercuring of water-based inks on the blog soon
How long should you wait to do a proper wash test? 48 hours?
Most issues with ink curing can be identified with an immediate wash test after printing. However, maximum cure for plastisol allegedly takes 24 to 48 hours. If you use a catalysed plastisol ink, full cure takes up to four days.
@@InkKitchenCZcams so you can still do a wash test right after it cools down?
It wouldn't be a fully effective test if you do that, but it would be some kind of test. Better to wait if you can.
@@InkKitchenCZcams ok, but ink won’t wash out if it’s washed the same day it’s printed? If it’s cured of course
If it's cured, the ink won't wash off.
