Narrative:

Cleared to taxi K; B; M to cross 4L approach end. At the intersection of taxiway B and M we made query to tower as to direction from this point. We were cleared from taxiway M on to runway 14/32 and hold short of runway 4R. As we turned onto runway 14/32 we missed the visual hold short line and did not penetrate runway 4R. I was not familiar with the visual hold line. I am used to the standard hold short line and was distracted by trying to determine our transition route from runway 14/32 on to runway 4R.
