Scoop coaters??
« on: January 17, 2013, 05:48:22 PM »
Are all scoop coaters the same? meaning their shape and angle of the v bend? How do you guys get all the remainder emulsion out after coating screens or do you just not both and wash it out?

I've got a white plastic spatula I bought from Publix a long time ago. Not the kind you use on the stove, more for mixing or something. The corners are rounded and I can rake most of the leftover emulsion back into the bucket.

Seems like they don't vary a lot, but the different models I have aren't exactly the same.

I'm a fan of rubber/teflon spatulas, a little bit of flex but they still get into the corners.

I've always used the AWT dual coat.  Like 'em a lot. 

I saw the co. that makes the ergo force squeegees has one out that looks pretty sweet as well.  Theirs is the first I've seen with some sort of change to the features. 

I use old credit cards or similar to scrape out the emulsion.  The new one mentioned above is designed to fit on of those disposable cards they sell but I find products like that wasteful and needless, an old card works fine and you can rinse/reuse it for a long time. 

Rubber spatula is a great idear.

I scrape ours out with a two inch plastic spatula, instead of wasting time cleaning the spatula I just let the emulsion dry on it and peel it off the next time it's needed.

I just bought the most insane scoop coater this week. this thing freakin rocks. It's called the Monster Max, it lays down the smoothest coating I've done yet. Great pricing too. NO more of those cruddy side lines from the ends of the conventional coaters.

Bought mine from Roeder Industries Titusville Florida.

I was just getting ready to post the same thing. Picked up one of the monster coasters last month and love it. Holds a ton of emulsion and lays down a nice coat. I clean mine with old business cards then wash out with water, dry and ready for the next set.

As far as I can remember I have always used a Tetko dual coater. That Monster Max has a unique feature, adjustable end caps to meter the emulsion coating. Does it have a sharp and a round edge like the dual coater?

That's the one I was talkin' bout.  Nice that it holds more, that's my only complaint with the AWT, you have to refill too much.

Yes two edges. They recomend setting it and using the fat edge for a heavy deposits but for me it was too much emulsion. I use the sharp side now and getting nice coating, about the same deposit as the fat side of my old Sefar coater. The first time it was alwarkward when full of emulision, spilled a bunch.

That is actually a rad feature- you could use it to reduce the number of coats if you dialed it in.  Bumping down to 1/1 from a 2/1 or 3/1 would be huge for some shops.  You could buy an extra and have it just for those one hit wonder screens or hd work, etc.

I personally have some completely unfounded superstition that 2/1, either thick or thin edge is where it's at to ensure consistent coating.  I only coat 330s at 1/1 thin edge because it needs a very thin film for some jobs, but all else gets a 2/1 on either edge.

Like everything else I just need to find some time to play with the adjustments and get a perfect coat of emulsion.

This coater has gotten me from 3/2 to 2/1.

Ever since learning about EOM, I put aside my old advance sharp side only, and have used the rounded edge available on most others. It would take a lot more sharp passes to get the "glisten"
I have a couple, a Tetko and Sefar, I think. They have two different profiles, but I merely cut a card out of cereal box cardboard to match the one I''m using, and scrape out the unused emulsion back into the bucket.
That rug really tied the room together, did it not?

I've experimented with sharp vs round and with my technique and all the guys I've had coating for me the round wins.

Zoo, a 1/1 sharp on a 330?  Doing the glisten on a 330 takes us a 3/1 and it's still a very thin EOM, probably around 10%.  I could look at my notes and tell you for sure but I'm lazy.  I remember it being well under the 12-15% but it does work well for getting those finer halftones with a pure photopolymer emulsion.

Did that scoop coater come from Shaun Roeder or is that a coincidence? Looks like I'll be trying that out
