I find it weird to do a print on rc then to fiber, its easier to just cut a test strip and then do a print on a full size sheet. If I am working with larger papers, I make test strips out of a sheet thats smaller so I dont have to destroy a sheet of the larger format. And also print a section of the image to evaluate tones before going for the big sheet. Lately I have been getting a bit lazier about this, but I can still guess pretty well what exposure is needed and be close.
