Are you talking about offset printing? Are you referring to lacquers and varnishes?

I am interested to hear from folks that are using aqueous based coating in
either the web or sheetfed industry. Understanding that the local
municipalities play a major role on drain waste, how are you discarding your
"washed up" diluted solution? Most manufacturers indicate that it is "drain
safe" but we all know what that means!! I am in the process of sampling and
approval for City purposes.
