The unknown consequences of pressing 0

[davidking623]

I know everybody and their brother seems to think pressing is the new norm except for me its not .I have tried to press something that is pretty wavy but not to try and go from say a 9.0 to a 9.6 or 9.8 I know it seems cool and its all about the money you can make . My question is what will be the real consequences if any say 40 to 50 years from the day it was pressed ? The unknown damage if any ? Thanks !

For some the consequences are immediate. Burnt books, color loss due to improper dry cleaning or too much humidity, specking, pebbling and worse. 
 

I have books in my personal collection that I pressed back in 2004/5 that still look the same as the day they were pressed. Cannot for a certainty say what’s happening to them in the slab, but from a sheer visual point of view I don’t see any changes.

Joey, didn't you do a break test on some pressed books way back when?  Am I misremembering that?

We did. The half that was pressed actually had more hydrogen bonds and the pages were more supple compared to the non-pressed half. 
 

I want to say Mike actually took care of the logistics while I provided the sample for testing.

Thanks, and to clarify this included humidification for the pressed books and not for the unpressed?

Correct. 
 

The initial control was the book sat in my work area (AC at 72 degrees and 50% humidity +/-)

The book was cut in half. The one half was immediately bagged and boarded, and the other half humidified and pressed, left overnight in the press and then bagged and boarded
