It's easier explained with a picture:-) The notches are the parts of the letters as seen here. You actually see "notches" where the letters overlap. I hope this helps.
ALSO...When there is overlap of images and no major separation between the images, the up and down lines as seen on the I and N for example, would be called grooves. You also see grooves on the other letters, it's just more easily pointed out on the word IN. So when you hear about notches and grooves....this is what we mean. The grooves run up and down, following the shape of the letter and the notches are the little "cutouts" so to speak at the very top or bottom of a feature on the letters.
Thanks,
Bill
