Digital BW, The Print

I'm about to print about 100 A4 size sheets (EEM - EAM in the UK). 
The sheets will be bound in a book - without any interleaving sheets.
 The inks will be UT7.  Storage will be at home on a bookshelf.

Does anyone know whether there are likely to be any long term problems
with the printed images arising from the printed ink side being in
contact with the back the sheet in front?

The answer may well differ dependent on the paper and the inks - and
of course the storage conditions, but initially I'm interested in the
paper, ink and conditions above.

Thanks in anticipation.
