Removing WB ink

What are people using to remove images from WB/DC ink that doesn't come out in initial reclaim? I have a couple stubborn screens!

have you tried this? We have had good luck with it. But I have had WB screens that just were no goes.

Yeah sometimes with very stubborn wb stains (where the mesh seems "dyed") you need to resort to the really harsh caustic stuff. Which sucks, because it's dangerous stuff that can burn/blind employees or destroy thinner meshes.

If you've used the more lightweight options and the stain is still there, I wouldn't worry about it unless it's affecting exposures or messing with stencil detail. I have several screens that have permanent black image stains. No effect on anything when I burn new stencils with them.

Agreed, if you are going to use this stuff you need to wear full protective gear. Full face mask & some rain gear with some good rubber gloves. ( think Walter White )

If it does not affect our prints, we don't do anything. If it does, we change the mesh.

All my fingers are wrecked because I use to use caustic that comes in pebble forms (industry standard here). I ignored the itchiness and it started to eat into my finger tips.

Another thing about concentrated caustic is, it corrodes Aluminium. I had half a kilogram of caustic and the pebbles were stuck together like ice. So I dropped it into a bucket of water, it started bubbling and the water got hot. I stirred it with an Aluminium rod and within second it turned black and the submerged rod was all dissolved.

IT IS NOT WORTH THE HASSLE, YOUR HEALTH IS NOT WORTH SEVERAL DOLLARS (after chemical, and time, you might have just saved several dollars).

The murakami 700 haze remover is magic, but you need gloves and a faceshield to be safe.

WOW! And this is the ink the customers seem to think is "environmentally friendly" ink!! As usual, the customers know best:D

Thanks guys I didn't think it would a big issue leaving the "stain" on some of them. Kind of a morale sucker punch though!

CCI GR-70 full strength gets all my WB stains out. Only ink that is a pain is CCI spot black. That one is hard. Got all the black out but there is still ghosting.

It seems like red is a bad one for us. We put in damn near half the day Friday doing some HUGE front prints for some proofs. Was a huge nightmare, now that image is burned into the screen forever to remind us!!!

[Screened Gear]

I used to use screen opener. GR-70 does as good if not better. Never have red stains. Plastisol stains all come out. Spot black is the only one in years. Just got the spot black last week.

The best way to be 'environmental' and remove those stubborn waterbase pigments trapped in the knuckles of the mesh is to use a 3000 psi washer with hot water.

Don't have that.. then a home depot special and a bucket of lye are in your future.
