Hello All..
We use Rutland Discharge and pigments.
For oranges and reds we usually bump up the pig loads for vibrancy + 6% activator.
Shirts come out of the dryer bright and vibrant.
Wash tests seem to dull out the color somewhat. Passable, but obviously keeping a bright print
color after washing is what I am after...
Will knocking down the activator to 4% have effect? Or, perhaps we are bumping up the pig loads
too much for the balance to be proper? We are getting good saturation and penetration, but shirts
seem to lose their luster after washing.
Thanks.
John

2.5 on the activator for reds.

John.......again; can't comment specificly but you are on the right track. Simple testing will probably yield improvement.

General rule is: Only add as much activator as needed to make the garment dye disappear/not interfere with the color of the ink.
I have found garments that discharge wonderfully with 3% activator and others that need a full 6% to discharge well enough.
Test Test Test.
I do wish Tony Pep could chime in again ;)

I hope most will understand. I have a crazillion formulas for DC that have been developed for over two decades. They include binders, PCs, and activators from all over. Been doing this back when most thought I was nuts. And yes, I have held out on a lot of technique and application however I feel that I have shared just enough to let others learn on their own.
After all thats they best way to acquire knowledge n'est ce pas?

Aside from everything else already mentioned, giv the CCI base a whirl. We use it with Rutland
pigs and I have a couple shirts that are years old and hundreds of washes and the red still looks
kickass.

I've found it to be really garment specific, for whatever that's worth. with wb and DC ink the print will wear with the fabric. If the fabric tends to pill up or fuzz out so does the print. This is one area where plastisol, printed correctly, excels on bad wearing fabrics.

Yup, exactly. With so many blanks to choose from it can get overwhelmingly dizzy for those new to water base and discharge
