6 color sim-process, discharge inks, going on white and black shirts.
We're getting moire, looks like interference between two colors.
But....
You can't see it on the white. Only on the black after it has discharged completely.
Yet another variable to contend with...

yay, fabric interference. At least that's my guess. Discharge sometimes reveals too much about the shirt that the dye covers up.
We once had to scrap a few dozen Ts that had crappy fabric mixed in on a tonal discharge run. Big nasty thread lines right through the image but you couldn't see it on the shirt pre-discharge. We had the same thought- how could we possibly prepare for this?

Winner winner chicken dinner!
We were testing on scrap shirts and seeing the moire, luckily the run was on AA
and printed beautifully.

stupid question here -and you guys would know...I had a job the other day that was black shirts and royal shirts. all the same art. 6 colors. I could discharge the black shirts but could I have used the same inks on top of a wb base white and not change out the dc colors or are you better off replacing them with non activated inks?...hope that makes sense...
