we are printing a 6 color sim process print. Something we've done at least 7 or 8 times. black shirts came out perfect! As soon as we switched to a white shirt though, moire pattern is showing up in at least two of the screens.
The image is a darker photograph, so maybe the moire isn't noticeable on the black, but what could be causing it on only the white prints?
-
Did you still underbase it on the whites? Sometimes the shirts can cause a competing moire with the dots. The base may have prevented it on the black shirts.
-
That would be my thought. Moire from the knit.
-
My guess is also shirt weave issues.
Try it on a different weight white shirt and see if it still shows up. Then try with the underbase.
-
we took the base off, only because it was a DCUB. but we can try putting it back on with white plastisol.
also going from a NL3600 black, to 3600 white!
-
We had one where we were getting a pattern between two screens so we re-burned at a slightly different angle
only to then get a pattern with the weave of the shirt. Sin amor por moire.

Another guess at fabric/weave interference. SUCKS when this happens. UB is the only solution I know of.
Weird that it's the same 3600 though...

this is what threw me off too. we are going to try it with the ub back on, see what happens.
