We use Sericol Discharge for our spot colors, and last week we were printing two projects with the Sericol TC-22 Red (from a 5 gallon pail).
We printed job 1 on an Alstyle 1301 tees, and job 2 on a next level 3600, both black.
We've always had fantastic results printing discharge on both of these tees. Both jobs were multi colored, and used a 156 mesh for the reds.
On both jobs, we used 3% for the activator.
On both jobs, we were getting inconsistent red coverage. The print was fine, but it seemed the discharge was discharging fine on random parts of the design, and coming out really dark on other parts. Each shirt was random.
Has this happened to anyone? At first i thought maybe they weren't curing correctly, but all the dryer settings seemed fine, it was at the correct speed and heat. Temp. Gun read the correct heat. I ran them through a little slower just to check, but no difference.
Is this possibly a bad formula? or bad mixture on our end?

Could it be oil spots on the shirt?
I have had prints that show where there was obviously "something" on the garment in the print area that would not allow the shirt color to discharge. Whether it was an oil stain or something else, I am not 100% sure on.
But you definitely have multiple shirts that look perfect? Sample/test print looks good?
-
It's to many shirts to be oil spots on the garments. Design 1 was 40pcs, and design 2 was 60pcs. All coming out with different degrees of discharged red

Is it possible there was inconsistent pressure, or something crudding up the screen in a way that made the amount of ink coming through it inconsistent? I have had this problem once or twice due to ink drying slightly in areas of a screen with a ghost image and it is only visible on large coverage.

nope def. nothing in the screen, this customer is EXTREMELY picky about lint, and spots in their big blocky design, so we keep a very close eye on anything weird in the screen. These all printed fine. The only thing i can think of is the red was the first out of two colors on design 1, and 2nd out of 3 on design 2. But they were on two different presses as well.

As long as your saturation is consistent I'd be looking at the garments. To be completely honest
we've not had the best luck with either of those brands and discharge. White on Alstyle tends
to be rather beige, and Next Level can just plain not co-operate sometimes.
We run our red mix at %5 activator contrary to most.

the weird part is the other colors discharged GREAT! we've never had a white issue with either of these brands.

If the other INK colors discharged great, in the same area, then it's the ink or your application.

Could it be a variation of zombie-skin? What is the print order of the colors.

We thought of this, but we haven't had that problem in a while now. It was 2nd out of 3, and the white screen (screen 2 on the two color, screen #3 on the 3 color) had little build up

gotta be the ink

Did you run them back through and see if it went away? The only problem that I have had with their red was an inconsistent cure. Those days are gone with the new dryer.

yep, was the first thing we tried.
Same thing just happened with a run of yellow we did on the NL3300L. Usually not a problem. This time, weird splotchy discharge.
I think it's the garments, cause the test came out great.

Eric......sent you a PM there is something I would like you to try
