Below is a video showing my use of fire to erase ink. However, the ink pen (Pilot Frixion) leaves an imprint in the paper. Is there a better ink pen to use that leaves no imprint?
the mark is caused by the pressure of the tip, so you either find a way to transfer the ink to a stylographic or a dip pen, or you use a paper that resist scratches, like the watercolour paper.
The easiest and most efficient way in my opinion is not to care about it, just press a little lighter (look! i made an unintentional pun!)
