How to remove grid paper lines from graphite pencil drawings in Photoshop?

Hello there,

I am trying to remove the grid lines from a technical drawing sample made with a pencil. So far I could only reach solutions related to ink or pencil drawing on white paper. That would be amazing to be able to separate the pencil drawings from the grid surface without losing any details. 

Thanks for all in advance!!!!!

I had hopes when I saw the thread title, but seeing the image my hopes faded somewhat. Far too much grid, far too little drawing.

The Remove Tool can ultimately do it, but you'd have to shift-click each grid line manually with a small brush. Expect some collateral damage, this looks like a very delicate drawing. An additional problem where the drawing and grid come almost together in horizontal/vertical lines. It will take a lot of time.

There is nothing that separates the two on pixel level, no color difference, no contrast ot tone difference.

Thank you for your reply!!!

Yes definitely a very delicate drawing, Initially I need to ink it or digitalize using Illustrator. However, both are very time-consuming so I thought maybe I could use them as it is - a pencil drawing.

I already tried your solution but it took more time than normally does.

Do you have a version of the image that is not as badly damaged?

Thanks for your reply!!

It's not damaged really, I sent a part of the whole page. It's only made in a fashion that would be transferred on tracing paper with pens. I have no problems with inked versions, but rather looking for a maybe quicker solution.

The color artefacts seem like damage to me. 

Did you scan the image straight to tif?
