I always tell my wife I will be in the darkroom for 45 minutes. I have four drying racks, so my maximum output per session is 4 prints (more if I keep some wet). Typically it will be 3 hours before I come out of a printing session with 2 or 3 prints made. One to my satisfaction. I may go in later and make that last print. Then I have to go back after first wash to tone, then go in after the final wash to lay on the screens. Toning and washing are often done the next day.
