Re: “If you know anything about the different types of paper stock you can tell at a glance, it is not difficult.”
That’s great, but how would you explain that to a courtroom? Anything concrete or measurable?
In the courtroom one would have the physical document, not a digital representation.
We all know what can be done with digital images.
8 1/2” x 11” seems easily measurable as would 210mm x 297mm
