“The typewritten characters should have darker and lighter portions within characters and from character to character and line to line”
This may be answered later (still trying to catch up) but, as someone with experience with manual typewriter of various quality) I wish to respond.
If an experienced typist with consistent key strikes and a good quality ribbon generated the document, assuming the machine has no “weak” keys, the document will be as consistent as one generated with an electric typewriter or a laser printer.
You will, however, see vast differences from document to document, because of the typist, ribbon quality as well as the quality of the machine. You will not normally see that with electrics because the strike is not dependent on the input and ribbons were designed not to overstrike.
The type-written characters look to me to be created with a typewriter, not forged digitally. The form itself is printed with fonts that need to be further analyzed to make sure they are vintage 1964 fonts, not modern ones.
Good point. There is the question of the age of the machine. Had it developed identifying quirks?
