Hi Guys..
We are by no means a waterbase shop.. but we are getting better.
I have on deck:
3 Color print, Rutland water base. Screens post exposed. Simple print...
Would this be best run wet on wet? During sampling, we were running a QUIK flash after head # 1
to set the ink, but things went downhill quickly.. 1/2 tones seizing up, some gumminess in other print screens.
My best guess is to move forward wet on wet, and I am pretty sure thats what you guys will say.. Just looking for
a confirmation.. Thanks. John

Print order?

Always WOW with WB and DC.
I have noticed that partial flashing (or really "drying") a DC UB with a plastisol top can really improve the opacity and sheer of the top plastisol color but we've never flashed any of our straight WB/DC prints. Up to six colors here- spot color on 150, sim pro on 330 typically and up to around 300 pcs has been our max run for the 6co stuff. If you keep it moving you won't ever need to stop and wipe down. This is on the ol' manual so it should be even easier to keep it going on an auto, so long as you can flood at rest. Dry in has been practically non-existent so far but we do also print flatstock wb ink that is hyper aggressive when it comes to dry in so we have that urgency when on press with the textile inks.
That flash might be introducing too much heat around your WB screens as well.

I'm guessing your putting that dusky blue fade over the white which would be a no no.

Hi Everyone..
OK. Just great. Sample just came off the press. No flash.
EB - lucky on this go round... printing only 3 colors on heather, no white. 3 screens (2 solid fill, 1 gradient)
See [attached] 1900 shirts. This advice makes me a better print shop. Thanks fellas.
