What is this occurrence called and how does it affect the grade? 1 1

What is the term used when the color, usually red, can be seen through the front cover of older comics? How does it affect grading? In the attached example, you can see the red color from the art on the back of the cover bleeding, or shadowing, through the front cover.

It's called "bleed" and doesn't affect the grade, refer to above if you want a lot more on the subject.
