screen printing > Waterbase and Discharge

Ryonet advertising their own brand of discharge base and pre-mix white?????

Frog:
I think that in this instance it would be fine. Certainly better than the copy and paste posts that seem to keep some places going.
What we don't want are links to negative crap, or inter forum intrigue.

We are still new to the water based system, our customer base is loving it and we see ourselves doing alot more of it in the near future, but the white has been a huge issue. I have found the Matusui pre-mix white, mixing it several different ways that other printers have advised still mixing up like ricotta cheese in texture, then clogging mesh of all types. The best result that I've had with the white so far was adding so much water to make it creamy that it really made a mess on the auto. I add print gen to the mix as well but we still end up with a chunky mix after a while. I could deal with a lil stank if the ink stayed creamy, flowed nice, didn't clump in the screen, and had a sweet finish to it. Thanks for the info Dan!

Hey Mike,
It's all in the mixing technique and knowing that 301 bases and white inks don't like the activator and are known to clump. You need to compensate for the lack of moisture in the whites with clear bases and water.

The best stand alone white ive made to date uses Matsui's Discharge Brite White with Discharge Brite base at 50/50 or 60/40 mix and 5% activator.
When I add the activator, I add it to a small cup of water = to 3% ink weight first, swirl it around till it dissolves and then add that to the ink and stir. It won't clump and is one of the brightest whites you've seen.  For problem shirt colors use the 60/40 mix and p-f-p for a really brite white.

Hey Mike,
Yes, it is CCI. Good stuff. But Matsui is great as well. However, with the CCI inks you only have to use 3% activator. And I agree with John about the discharge white and the discharge base mix. But to avoid any "clumps" we mix the white/base and any pigments first, then the fixer, anything else such as water, and then dead last the activator. If doing large runs just mix a gallon or whatever you need and then before going to press add the activator. Have fun!

Ryonet isn't the only distributor private labeling CCI's discharge base and white and activator.  I'm not a fan of their white as a stand alone, but have been using the base/white in combination for UBing plastisol with good results, very easy to print.  The activator works well with other brands of ink as well.

My vote for stand alone white is Rutland White Plus (straight out of the bucket w/6% activator), prints easy and it looks great even after dozens of washings which is more than I can say for some other brands of discharge white.

screenprintguy:
Thanks Guys! I have gone to diluting the activator in water before mixing in, mixing brite base, pre-mix white, and print gen first, then adding the diluted activator. After about 20 seconds the whole mix starts to tighten up almost like the activator activating the white part of the mix starts to seize. Then I'll add more water little more print gen, but no matter how smooth the mix starts, I keep ending up with this ricotta cheese type texture, it's a real P.I.T.A. The last run we did with white, I had to make it so watery I couldn't back flood or it was starting to drip through the mesh. I'm not giving up on it, just trying to find my even ground, my customers are all over the prints so I really need to perfect my white. All other pigment mixes have worked out awesome. I haven't had any seizing of discharge mixed with other pigments, just the white mix. That's the only reason I asked about this advertisement, he makes it seem like it's a ready to go issue free mix, but we all know he's a good video salesman so until you have it in the shop you really don't know. I'm going to ask my guys at SPA what other white they are carrying and I'll email someone at RY to see if they can send a sample. I'd like to just get what I have here working and stay with one system. Practice makes perfect right! Thanks again for all the pointers guys!

Mike
