Help? Idea for how to test a hypothesis?

In order to test a grille, you will have to make a device (cut us piece of carton) and put it over the text yourself.
Myself i ordered a printed version of the manuscript, in order to check such a thing.
You can also use it on your screen if you do not have a paper version of course.

There is no automated possibility to do this by my knowledge, because you would need an OCR possibility and need to connect to the OCR software to test your algorithm. Such software is bit valuable and not easily available.

What you could do also, is place pages on top of each other in a graphical environment in (transparent) layers, and see if there is something lined up.  I believe there was someone on youtube doing the same with the manuscript, i believe, and presented it as a "solution", although there wasn't any.

Problem with any method is this:  basis of the test are the photographs of the manuscript. These are NOT 1:1 scans, but photo's. This means one page's text is in another angle than the other and in another scale. You can not be sure if the size of the page is actual size.
