I posted a question earlier in the week regarding a sefer that seemed to be getting water damaged easily, and what could be done to waterproof the ksav somewhat. I am still a little worried about this sefer, and would like to share my predicament with members of this forum, in hope of receiving some advice or insight.
Some months ago I sold a new sefer Torah to a shul here in Melbourne. The sofer who wrote the sefer is a sofer mumacha with a beautiful ksav. As usual, I had the sefer checked first by computer, then manually, then tikkunim (repairs) and then a second time by computer. (The magiha who did the manual examination is a magiha mumcha with 30 years experience and although he charges twice the usual amount for the job, I find that it is worth it because he is extremely reliable).
The sefer was used for a few months and received many compliments from all who saw or lained from it. So far, so good.
Two weeks ago however, a problem was found and it was put back in the middle of laining. A stain was found on one of the letters which totally passeled it. See the picture below. I received the call from the shul after Shabbos and naturally I was very disappointed and somewhat embarrassed. See the picture below of the stain...
I was convinced that such a stain surely would have happened after the Torah was already in the possession of the shul. Perhaps a rain drop had fallen from someone's hat or the like. To prove it I asked the computer examiner for the photo of that omud from the second computer check. Of course it did not have the stain. Furthermore, if you looked at the stain you could see that on the back of the klaf there was a black mark corresponding to the place of the stain (see below), indicating that the damage occurred after the sefer was already on the aitz chayims and most likely after the siyum.
So I explained this to the relevant parties, and emailed them the original computer image (see below).
The very next week however, also in the middle of laining, another problem was found. This time it was a mark between 2 letters. See below.
Again, I felt there was no way both my magiha as well as the computer check could have missed this. So I asked again for the photo of the second computer check, which again, was clean (see below).
I again explained to the relevant parties that I am 100% confident that this too occurred after it was already in the shul's possession and that it was most likely caused by spittle. I explained that the problem is not the fault of the sofer or that it was not checked properly.
The rabbi asked me if perhaps there is something wrong with the ink. (Fair question, given the circumstances.) . He told me that he had never seen such a thing once, let alone two weeks in a row. I checked with the sofer and he told me he used Dyo Nahari, which is the most popular ink on the market. Furthermore, and in all fairness to the rabbi's concern, there are other sifrei Torah in the same shul (which I had sold them in previous years) which were all written with dyo Nahari and never had such a problem (even once) over the years.
I am now worried that this may happen again. If it does, not only would it be seriously embarrassing for me, it would also be very embarrassing for the donors, who are already somewhat concerned. This was not a cheap sefer, and none of the other seforim in that shul are showing any signs of damage.
I thought about waterproofing the sefer with fixative, hence my post earlier in the week. I'm just worried about the long term effects it may have on the sefer.
Any advice or insights would be appreciated.
