The requirements are clearly nonsense.  However, they make good sense if 
the stated size requirement of 110 cm is actually 110 mm (4.33") 
instead.  Then an image of 1024 pixels spanning 4.33" gives a resolution 
of 236.5 pixels per inch which is well above the stated minimum of 80 
ppi.  80 ppi is probably OK for screen viewing but would make a very 
poor quality print.  236.5 ppi would make a good but not outstanding 
print.  I think there was a failure of proof reading.
