Why: To avoid any ink marks that would spill over from one field to another. If both fields A and B are to
close in proximity and the ink marks from field A spill over to field B, then the marks captured on field B
would be considered as being part of a character written on field B. For example, if a number spills over and
is written over two fields like numbers 9, 1 or 7; then the bottom tip of these numbers could be considered as
number 1 in the second field. (Refer to the example below)
