Re: [BKARTS] non-flattness in leather covers



attempting a specific focus:

Yes, it is no mystery that one material adhered to another will exert some force. And balance may be achieved by a opposing force on the other side. And that these are factors the binder must account for and control. And that a fine balance may be achieved.

Will this balance persist in changing environments? It seems reasonable to expect the opposite surfaces will have a different exposure to atmospheric humidity, that this will induce changes in curvature of the surface.

It also seems likely that, unless the two surfaces are covered with identical materials, the two surfaces will react differently to changes in humidity even if they have equal exposure.

Comments so far, with some exceptions, seem to imply that a final state will be arrived at once the binding is finished and dry. But isn't it true that shape of our books is dynamic?
