M.I.C.R. font not spacing correctly

I need to set a check, the MICR font is 12 point with equal spacing each space and character = 1/8 inch.

I set the type at 12 point, kerning set to "metrics" tracking set to zero.

Yet my spacing is not correct. I am nearly 1/16 off horizontally.

In QUARK I have a H&J's contol which allows me to control a text box's kerning hyphenation etc.

In the past I jas an H&J's setting called MICR and any text box had MICE H&J's assigned.

I thought METRIICS was the equivalent to the font's native em en spacing and negated any H&J's type of override

How do I get the font to kern/space correctly at 1/8" em space for each character?
