Brightness Adjustment for Blurb Book

when print on epson r1900, have increase brightness (+20) in print module on prints. 

there no corresponding option in book module sending files blurb. 

how can make equivalent adjustment blurb?

 

i assuming blurb profiles close enough epson profiles (as far brightness concerned).

if have edit every single image separately, best way this? 

is exposure equivalent of brightness in lr 4, , metric same (i.e. increasing +20 in both)?
