Post-exposure dip tank?

[ebscreen]

Unlike an emulsion removing dip tank, the contents of this one are the price of water.
Use anything you can fit screens in comfortably. Ours happens to be a stainless tank
for some reason, holds 8 screens or so, tap at the bottom to change the water when necessary.
Gets stinky during the summer every month or so.

A soak is a heck of a lot more consistent than a spray with a hose.

We use one. It's definitely more of a luxury than a necessity. We typically fill ours up with about 5 screens at a time while burning loads of screens and then wash out as we're adding new ones in the water tank. It really just creates a cycle and gives the employee something to do while waiting on a screen to burn. It also makes wash out a lot easier and you don't have to drill down on a screen with a pressure washer.

Similar to how I make Solar plates at home for intaglio printing. Essentially cap film laminated on thin aluminium. Exposed in the sun using 3/4" glass. Sit in water tray for 1 hr. Finally plate is gently brushed with brushes or seagull feather. Sounds ghetto but when done right extremely professional results may be achieved.

I've been thinking about a black tank on the roof and circulating water through it.  Will provide agitation as well as warm water (for free).

Any thoughts?

I've been changing out the water every couple weeks.  Ours is a smaller unit that only fits two 23x31 screens so I can pick it up and drain it easily unlike the reclaiming dip tank that takes some serious muscle to move around.

That's nice, if it wasn't that the one I'm using wasn't free, I'd go for a smaller easier to move around tank. I actually have ours sitting on top of one of those home depot style heavy duty flat bed carts, so we can roll it out or move it easier if we need to. When it was in the back of the shop, it just sat on the floor and i had to run a huge pool drain hose outside and hook it up to a sump pump to empty it lol. Think its time to dump this one, saw some slime in it today, don't need some weird supper bug mutating in it lol

Love the post exposure dip tank, many have seen this video of how we use the tank with CTS Exposure and washout, but here it is again.

However, I am thinking I am going to have to re-think the work flow once the LED's are added. May involve some crowbars and such stuff ...

Greg's always coming up with cool ideas!!!

Greg, that hose going into your water tank, is that a recirculating pump hose, fill hose, or air hose to agitate the water?

Electric cord to a 110V 1200W Stock Tank heater, (think cattle & hogs have to drink in the winter) with a thermostat, warm water works better!

This was my original thoughts for heating the water.  That's when I started thinking about thermal hot water on the room.  I wouldn't think it would take much of a tank on the roof to really capitalize on the sun for this purpose.

A little clever plumbing should eliminate the siphon effect as well as purge out any air in the line.

turn your dip tank horizontal (ok, so it's not a dip tank, it's a plastic tub), keep it 8" of water and you can keep burning screens and feeding them to the bottom of the stack - no time holdup of only holding two or four (also much easier to clean as it WILL get scummy).
