Guess I'll have to get myself a freezer unit. Had not heard about this before. Does the impression hold after unthawing?
My experience tells me differently about waterleafs. I have had very little trouble with waterleafs or internally sized papers. But I have learned to steer away from externally sized papers, such as those formulated for watercolor work. You will have shrinkage and expansion issues due to the dampening process itself. This is more an effect pronounced by grain direction than it is from sizing, or the lack of it, as far as I can tell.
The project I did with the Arches 88 involved a form that filled the entire bed of my SP-15, ran five colors per sheet, with extraordinarily difficult registration and coverage from top to bottom. And, over a five day period. I did experience initial registration problems, but they were do to a presswork technique I was neglecting rather than any factor of the paper. If the paper is cut so that the grain direction allows the paper to hold to the cylinder rather than flop away from it, you will generally experience far fewer registration problems. I would not hesitate to use this paper, dampened, in future work.
