Your ink supplier should be able to provide this info.
Depends on anilox BCM (900 cpi & 2.1 BCM) and % solids of inks (solvent based ~20%).

thank you. actually this is for costing purposes as we are preparing for our gravure press. what our suppliers wanted is measure weight of unprinted film and with print to get the actual. we need a sort of formula to advance projection and forecast as we try to bid and be qualified as gravure printer. thanks

So you want to calculate a flood coat weight.
Weight before,
Weight after,
Subtract to find difference,
Divide by area size,
Calculate to whatever units you want., lbs, gram, inches, feet, etc.
If on non-porous substrate (film, foil), can be done directly.
If on paper or board, need to test on foil.
