AP Check design via BI publisher - Precision MICR placement

We are considering moving our AP Check from Crystal to BI Publisher.  Microsoft Word does not seem to lend itself to precision placement of text.  Placing the MICR line at a very specific point in Crystal is very easy.  We have tried in Word, and can't seem to get the MICR line in the correct spot for the bank.  Does anyone have any suggestions on how to do precision placement of the MICR line on the AP Check in BI Publisher via Microsoft Word?
