Lines on paper that show up on the scan

With the current notebooks your can’t see the lines on the lined or dotted paper on your scans, it looks like just a blank paper with notes in the PDF. Possible to make loose paper or a Notebook that has darker lines so the camera will pick them up while scanning or somehow updating the app so it will see them. I take notes for college and it would be very useful if I still had the lines that I’m writing on viewable on the scan.
