Removing pressed pen lines experiment...
Before and after. I could not fully remove the pen imprint, and I was starting to lose other colors. This was a pretty significant effort for probably a mild change. I used a surfactant to lift the ink- I thought this was a great test subject because of the white background.
I have a very expensive book with ink like this and wanted to perfect this process before trying it there... I will not be trying this on the book since its only a marginal improvement.
