I think many of us has heard about the Xerox copying machine changing digits on copies, using a "visually similar enough" replacement algorithm. https://www.theverge.com/2013/8/6/4594482/xerox-copiers-rand...

I wonder if you could get the same unexpected result when copying images of Western blots?

It's probably not the case here but it could be devastating for a researcher to be accused of fabricating data by using an affected copier/image editor/file format.
