Are you guys flashing the WB white and then printing your top WB inks? Can it be done with out flashing? It just feels wrong to me. Will the underbase WB white and top WB mix when in the dryer? I know when discharge over lapping colors will mix. WB and DC can make the mind go funny sometimes. Its like another language compared to plastisol.

I didn't get my gallon of pure white. I ordered it the night before my rep left and they didn't get it on his truck in time. I guess I will have to wait. Its ok I have plenty of other stuff to mess with.

Hey, yes, flash after the underbase white and then print on top. White is straight up water base, no discharge here.

And I just called my guy and have a gallon of that CCI White WB on it's way. I am sure it works just as well if not better. Will let you know next week

Thanks guys - I will get hold of our CCI rep as well and see if he'll give me a gallon for testing (they can be good to me that way).  They are about 30 minutes from me and we do a lot of business with them so I'll definitely check it out.

Yes - as for print method - pretty much just like a plastisol print in setup with a flash after the base - the flash needn't 'cure' the ink, but simply set it well enough to over print with your colors.    We have done high color water base sim process type prints with a discharge base for some time, but this is just something I stumbled across recently and there are times where I feel this technique might be more advantageous than trying to use a discharge base.

Brandon/Jon, I would be interested in hearing how your tests go.  I have some prints that are being sampled currently - between  7 and 8 color jumbo prints on micro-modal fabric (basically a type of rayon) we are going to try this method with one of them and do some wash testing afterwards (before finishing the sample runs - 4 sets of art total).  If it works well we plan on doing this for all of these prints for both the rest of the sampling and the production - I am not too worried about the prints, but am a bit unsure of how the ink will react to the material and the color fastness for the wash testing.  I should know more by about Friday or at latest Monday and will be glad to post back on the results if you're interested.

Did the test today on the micro modal fabric (black) 100% water base using this method - print looked good - went out to customer for wash test - that's the test I am most interest in - how well will the wb bond with this fabric (some sort of soft thin man made rayon blend).

If the wash test comes back successful we are going to all of the designs we are sampling for the customer this same way.

Post more when I know more. :)

Dave does the waterbase white block die migration? I know that is a newbie question. I have only done 100 percent cotton so far with waterbase inks. I am sure it doesn't so how do you deal with that with a waterbase ink?

We used Permaset Supercover white on 100% poly dry fit tees. No die migration at all. But I`m sure it depends on the garment you use.

Those 100% poly dry fit tees suck. Non at all? Did you print flash print? Did you turn your dryer down like you would with plastisol or run them like normal?

Don't know about the dye migration Jon.  What I can say is the print looked really good on the micro modal and had zero hand (black garment about 3.5 oz - kind of a pain to print on, but the customer does high dollar tees to boutiques with a niche product and market. 

Customer got the sample shirts today and wash tested - no fading - no issues - loved the hand and colors.

Good to have another method to do things with wb inks now that will work when more standard methods we might use won't!

Again - we have not been doing this long so I can't say more than I know at this point, but the process seems work and allow flexibility in ways that I would have though would make a water base print next to impossible to pull off successfully so I am pretty happy about it all right now!
