I have read from many different Sifrei Torah as a Ba'al Kri'ah during the past approx. 30 years. Each Torah is unique, as B"H, it should be. Every sofer has a slightly different writing style, even when there are strict rules for writing each letter, each word, and the spacing of each word.
I have been considering writing a book that focuses on the interaction between the writer and the reader of Sifrei Torah. I'd like to get an overview, preferably from those that are or have been Sofrim, if a Sofer thinks about those that will eventually read his work?
Is he diligent in making the letters clearer, larger, darker? Does he carefully space the letters do that it is easy to read? I noticed some sofrim love to stretch out some letters. Some do it often; others rarely do this. (I will probably post a separate question on this custom.) Some make wide columns; others narrower.
I have listed just a few examples. In general, I am curious if Sofrim consider any of these factors as being important to the Ba'alei Kri'ah or not.
