We are building A/C area for cleaning screens. What ink chemicals do you use that don't stink the room up. We had a open area with outside fresh air so this was not a problem. Im mostly worried about the ink remover. We use a recirculating tank right now for removing the ink. Then another booth for emulsion removing then a sink for degreasing. Some of you use a dip tank but we have a septic system and Im worried about ink down the drain. What do you use and how do you do it. Thanks
