Why don't washout booths drain in the front?
« on: July 28, 2015, 09:42:59 AM »
Seems like the most logical spot to slope the drain toward the front side.  I'm blasting water into the back of the booth. Wouldn't it reduce the possibility of contaminants being sloshed back up onto a clean screen?

I agree.

However, you will need to have a drain pipe then curved towards the back/wherever you have your drainage.  This will then create the possibility for that pipe system to become clogged.

Not that we as printers have ever had clogged pipes from emulsion... ever....

how about some design for the 'roof' of the washout booth to not drip on the freshly rinsed screens either...

This doesn't bother me much because you can elevate the screens with something like this (http://mlb-s1-p.mlstatic.com/13993-MLB169086521_605-O.jpg).


What I have problems with is holding the screens while we hit them with the power washer. When we wash them they're all over the place.
How about some sort of clamp or something that will hold them in place?

M&R made one years ago that held the screen as well as flipped it so you did not have to touch it at all. The product was called the flipper. Sold two and the customers who have them could not understand why people did not buy them and still use them to this day.

I don't understand this. I spent more time cleaning and reclaiming screens than I usually care to remember, and don't remember this as an issue. Assuming the screens are at a reasonably stable angle with a rail or something providing support in front at the bottom.
If only cleaning ink out, and not reclaiming, you should not be using the same force as with reclaiming. Like with degreasing, volume more than pressure does the job. Besides, I found that too much pressure could actually stretch mesh and lower tension.
If the problem is when reclaiming, is the emulsion sufficiently softened?

That rug really tied the room together, did it not?

I think the problem is the part he is using to raise the screens from the bottom...the pic he linked is just a flat grated piece.

My washout booth has three notches at the bottom that the screen sits in and keeps it out of the water. Assuming his does not have that.

no, mine doesn't. mine actually came with the stuff I posted earlier, we didn't buy it. there's nothing else there to sit it.

I am talking about reclaiming, yes, When we hit it in the bottom, the screen will always move around and we'll have to hold it and put it back in position. I am looking for something to fix it in place

If the top of the wash out booth was at a angle the water might run down the back wall and not drip on the screens.

Years ago i cut a milk crate in half and then put  v knotches on on the top, it held the screens in place in the laundry sink. Now i have a piece of coated grid shelving floating above the bottom. You just push it against the fiberglass walls to secure it and  pull it up  remove it to clean.
