How to clean stains in screens?
« on: April 30, 2012, 08:52:19 AM »
What do you use to clean ink stains in your screens?
I had a small sample of Haze remover from Franmar, and that worked OK.
Is that the correct stuff tou use, or is there something better?

Can you suggest something for me, preferably from Easiway, so I could order it with my other chemicals.

Thanks

Not Easiway, but our F.S.I.C or Xendegrade 2 works great.

Once again, not from Easiway, but definitely my favorite product for this is Liquid Renuit from CCI

I use and odd mix of CCI and ICC chemicals (bizarro...) but the best ink stain remover is the best ink degradent or remover you can get, IMHO. 

"Haze" removers are made to remove emulsion/diazo stains, which with any luck you're not getting because you're properly exposing.  Right?   ;)

Easiway 701 usually works with most stains for me and its a degreaser as well so it's in the dip tank, pressure wash, apply 701, scrub, pressure wash and rinse. If it's stubborn I do like frog and pull out the CCI Renuit and then a standard degreaser.

You shouldn't need to degrease after Renuit.

Well that's good to know! I was under the impression you always degrease after dehazing

You shouldn't need to degrease after Renuit.
While technically you do not need to degrease after Renuit ( for degreasing ) purposes, you should neutralize your screen with a neutralizing degreaser to remove the chemistry still in the screen.  For the time spent to do this will benefit you more than just about anything else you do in pre-press.

franmar d haze is a "use it every time" product.  works fine for us that way.

foo nailed it though- if yer ink remover didn't get 99% of it somethings amiss

What does a diazo stain tell you, overexposure?

I posted this in a Newb area :)
It is not diazo stain, I have issues with ink stains. I was asking if there is something that I could use to fix that. My biggest issue is not cleaning the screens right away :)
which I will start doing. I have some samples of 701 that I will try and I just had a small sample of D-Haze which worked well.

I do not have any issues with emulsion stains, and I'm using PC 701 photopolymer emulsion. Washes out as a champ :)

Thanks for the info, I'll see if I can get some samples in Columbus on ISS show this weekend.

And the winner is....... The Green Stuff   (for now)
I ordered a quart to try it. I was ordering a special effect ink start up kit to try that, so I decided while I have free shipping to try The Green Stuff too

If you check out a haze remover, most of them are caustic soda, sodium hydroxide I think. Works great, but is very, very nasty stuff. It'll burn your skin like nothing, and don't leave it on too long or the screen will literally tear itself apart. Yes, I found out the hard way, lost about 20 screens in a sink while I answered the phone. It is better indeed to not need to do it at all though.
