The baseline of K1 is basically straight, although lacking in the precision shown in Q1-3. The top lines are also quite straight, but are formed naturally by letters that are consistent in height. This exhibit shows top and bottom line straightness in K1 and Q2. The top line is from Q2 and the bottom is from K1. As further illustration of this characteristic the known and questioned writing have been optically overlaid and photographed through a comparison microscope.
Color is achieved by using filters on the microcope's illuminators.
The red is the questioned writing, the green is the known, and the black is where the two overlap. There is more range in this characteristic in the known writing than in the questioned writing. Although the writing is hand printed, there are connections from letter to letter and places where adjacent letters touch. This is a characteristic which could be more closely examined on the original document, but it is clear enough from the copy that this characteristic exists in both the known and questioned writing. All that remains is for the original to be produced to ascertain that the questioned material was actually written on that document.
