Re: [BKARTS] non-flattness in leather covers

[Don Drake <ddrake@xxxxxxxxxxxxxxxx>]

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?
