Question about production error as it relates to grading 0

[Pkav85]

Hello, 

This is my first post. A few comics that I was going to submit to CGC for grading but noticed some odd (what appears like production errors on the inside of the pages), Below are a few examples but they almost look like highlighter marks but they appear to be printing press color errors. Has any one experienced these before in their collections and do you know if these impact the grading with CGC. Any information will be helpful.

Those don't count as errors. They will detract nothing from the grade.
