Well, you're close. "The best method" is to align on something smooth,
with low dot gain, that matches your target medium in thickness. That
last part is very important, because alignment varies with printer
thickness.

Has to do with the time it takes ink to get from head to paper, vs the
distance the head travels horizontally in that time.
