Title: Reclaiming S mesh
Post by: TCT on January 25, 2014, 03:48:57 PM
On the Murakami website and also the Murakami rep said not to use a stiff bristle brush for reclaiming the S mesh. The stiff bristle brush has been a staple in the screen reclaimers tool belt at our place since the beginning.
What are you guys using on S mesh screens for reclaiming?

We use scouring pads with handles like these:

Just be sure to get ones that aren't too "scratchy". The ones we get are pretty soft and only last a month or so.

We use a dip tank and love it. 

I never want to go back to spraying/scrubbing it on. 

But we do use the scouring pads with handles for applying other chemicals and we love them.

We use a dip tank also, but still need to scrub out some ink occasionally. That Inkworks posted should work fine, I'll just pick some up tomorrow!

I am personally over the scrubby pads. I hate em. Easiway 701 pretty much destroys most of them. The fibers break down and on coarser mesh they get stuck when reclaiming. It drives me batsh1t.

I'm looking at other options.

I believe they recommend a sponge, I'd suppose you'd want to wipe out all the ink you can before you remove plastisol with one though.

Dollar store?  :)

Uh.......no. :o  We are creating a quantum leap in reclaiming.  From the mind wherein the Newman roller table sprang forth comes a true reclaiming solution.  Stay tuned.  Call me if you want to get on the waiting list. 8) 8)

Naw, I'd just like to keep hearing vague generalizations about industry changing products, thanks.     

Although, now that you mention it, I AM getting a little sick of my false reclaiming system.   ;D

Let's say you could replace the water in your pressure washer with degradent. (flash point hazards aside)
Do you guys think that would be enough to remove even stubborn poly white plastisol?

Actually, we've been told to avoid the scrubbies too and have switched to soft sponges for the S mesh. . .

We've heard great things about the Cell-O Sponges. They are the ones with one really soft side and the second side has a harder "mesh" scrubber. We don't do much reclaim here, so we have to depend on our customers for recommendations. If you are in the market, check them out and see how they work for you.

I tried the gong brush recommended in another post...with poor results.  We got one at lowe's, two at home depot, and one from an auto parts store.  None worked well.  2 of them were simply too stiff, even though they were pretty soft to the touch.  One was shedding small fibers like crazy, and the one where the bristles actually seemed right still failed to properly and evenly disperse the 701.  Back to the scrub pads like the photo listed above.  We get ones from walmart that are 97 cents and utter crap, but they are soft enough to not damage the mesh, disperse chemicals well, and get out all the ink/stains.

Al from Murakami here.  OK the reason to avoid stiff bristle brushes and scrub pads is that S thread is very thin thread.  So Ozite pads and stiff bristle brushes can act like sandpaper on thread that can be the thickness of a human hair or less in the upper mesh counts.  The whole reason to use a soft sponge is to avoid putting tiny cuts in the thread that later on may cause the mesh to pop.  Whatever you decide to use here is a test:  Scrub the back of your hand.  If it scraps or scratches your skin it is doing it to the threads as well.  Chemistry in dip tanks can do much of the work.  Whether it is to reclaim, or to dehaze the images.  BTW, washing your screens right after production prevents much of the haze.  I recommend using soft sponges for degreasing or reclaiming, the chemistry does the work! Also avoid sharp corners of dry wall spatulas.

Here is a detailed article on using S Mesh
http://murakamiscreen.com/wp-content/uploads/2012/06/The-Power-of-S-Mesh-1.pdf (http://murakamiscreen.com/wp-content/uploads/2012/06/The-Power-of-S-Mesh-1.pdf)


S thread has some unique advantages.  I can print 45 and 55 line halftones on 150S mesh that simply cannot be printed on a 110 mesh typically used for base plates.
Here is a video of me printing at an ISS show a while back:

ISS Show 2011 Murakami Screen 150 S Mesh Screen Printing Video (http://www.youtube.com/watch?v=WFShG5cWeGY#)

Watch how little squeegee pressure I use to print the whitest base plate I have ever been able to do in one pass.  The ink doesn't matter.  150S has a 51% open area, 110T has only 43% open area.  That extra open area means less squeegee pressure.  This lays the ink on the surface to give you the best 'soft hand' feel you can get on a shirt.  110T drives the ink into the shirt.  The image I printed is a 55 line halftone at 22.5 degrees.  The one other tidbit I will give you is you will use a lot less white ink with S meshes.  I have a major 40 auto shop that will save 30% of their white ink cost this year and make a ton of money in the process.

Outdated?  Hardly.  Answers for success?, you bet.

That looks really similar to one of the brushes I got from Home Depot.  I'll see if I can find a link to it on their site a bit later to compare. The flagged ends left little fibers all over the screen.

Just started using S thread mesh and I love it!  The walmart pad I am using is soft enough that it does not scratch the back of your hand and I have seen no abrasion issues thus far.  As a bit of a tangent, is anyone using a degrease/dehaze dip tank?  I would love it if that actually worked...no scrubbing at all!

I can ask the guys at Murakami here in Japan who actually make the mesh what they would recommend.

That`s the ones we use as well for 10 years now and never had any issues.

The ones I use from the local Home Depot work great. They start off a little stiff but once broken in they're fine.

I would prefer to use sponges or the light scrubby pads but the 701 just eats them up. The brushes just work every day.

BUT - if they broke down I'd have to look for something else. Maybe different Home Depot stores source products from various sources and you got some duds?

Yea, it definitely did not work.  I will probably just order the one linked above or keep using the walmart pads.
