I'm having trouble getting a good red with Sericol Texcharge. Originally tried to get a 186 and it was coming out really light, almost pink/salmon-ish. Wasn't sure if it was lightening up from either:
- too much activator (used 4.5%)
- getting picked up on the back of subsequent screens
- the fact that it's printed on top of a light cream underbase (also texcharge)
I tried a slightly darker red, 187, with 3% activator and the screen is now second to last in print order and I'm still having issues. I'll see if I can get some pics posted but is there anything I'm missing/doing wrong?
I'm now trying the Red Blue Shade straight out of the bucket with 3% activator as I saw a great pic of that posted by Alan.
(screens are all 230 with 2 quick strokes, every other color looks great)
Thanks for any help!

Try punching it up with a PC if you have any

I would be looking at this as an issue especially if it is being stepped on again after the red. Is there a reason why you are trying to print the red over a cream base?

Agreed. Did you try printing the red screen alone without the cream? That'd isolate that variable in a hurry.

Didn't read all the way. Activated discharge colors never need an underbase. Kind of defeats the purpose. Totally will mess with your formulasSee if you can find the Before and after thread. Should enlighten. And it has pictures!

Everything they said, and I'll add a little bit to speed up production. Next time, put that on a 150/48 or 180/48 and do one stroke instead of two.

Sepped by DTD - the underbase is a discharge color as well (sorry if that wasn't clear before) and I assume it's used to lighten that portion of the design and provide for some shading/tone variance.
The red is supposed to lighten a bit at the bottom of the print (when I have a second I'll try to get a pic up) but it was wayyy off. Tried printing it solo to see if it was just the base but it was still off. We switched to Red B/S straight with 3% activator and it's been much better but I was wondering why we couldn't get a nice 186 red (granted those are starter formulas, but still)

Without seeing a pic, I think that's just the two mixing: Cream + Red = pinky cream/red
I would 86 the ub, not needed, as mentioned above. Or, for the quick fix, switch to HO or high pigment load WB red or soft hand plastisol and flash that DC cream before you hit it.

Red BS with 4% activator gets a KICKASS red!
