Afaik I've had no issues resulting from an overnight soak either. Sometimes one finishes printing much too late to stay up to air dry and flatten prints so they have to stay! Sometimes I'll toss them on the screens and come back the next day, re-wet, dry, and flatten. Sometimes they retain enough moisture or are small enough that the overnight drying hasn't made them too wrinkled or too dry and I can just pop them in the press. ________________________________ From: Myron Gochnauer <goch@xxxxxx> To: pure-silver@xxxxxxxxxxxxx Sent: Mon, February 8, 2010 5:32:39 PM Subject: [pure-silver] Re: Wrinkles The other option is to leave them in the wash tank/tray overnight but that may or may not be detrimental to the paper and may or may not wash out the optical brighteners. You can test the effect on optical brighteners by using a UV "black light". I have never had an overnight soak affect the optical brighteners. I'm pretty certain the brighteners will not wash out uniformly. ...after forgetting about a print in the washer for three days, the brightener pattern was ugly-blotchy. Myron
