traveller1st I just felt a bit butthurt by "It’s called copy degradation.".

Don’t worry about it.

And I guess you guys are right. It is very likely to be real. It doesn’t make sense for it not to be. Sorry for being a bit difficult.

You aren’t being difficult it’s called exploring the possibilities and asking questions. As for being a bit hurt by that comment? lol it was not intended as a hurtful comment. It was just a statement. I wasn’t implying that you (or anyone) wasn’t aware of that.

You’ll get used to the ‘tone’ of replies eventually. I used to think it was a bit harsh but now I just think it’s funny. It’s how we hash things out to get to a reasonable consensus.

Hey, you spotted the scan lines weren’t folds so kudos there. It probably didn’t get much attention because it wasn’t arguable lol. We do like a good arguem….I mean discussion.

Updated the "see through" image of the 340: https://drive.google.com/open?id=1qP26V … YsWFGOiCSR (very high-res)

It is basically a redistribution of the gray-scales and blacks of the letters so that the darker areas (more inked) are more pronounced. Darker areas are typically where strokes connect and this gives insight on how Zodiac wrote the symbols in the 340. An example is the following, the squares always start in the upper left corner. As far as I can tell all symbols have been written in the same manner and I feel that this level of consistency may be unusual. Usually people deviate here and there, but not Zodiac.

Triangles start in the lower left corner.

you are a man of many talents jarlve..
much respect
cheers

Thank you Mr lowe.

Here are the line symbols. Horizontal lines drawn from right-to-left and vertical and diagonal lines from bottom-to-top. The 3rd horizontal line symbol may be an exception.

Hi Jarlve

Are you going to test this technique on the other 340 KEY that was mailed in? The key from the thread You recently posted on?

Hi Jarlve

No. It requires a uniformly lit high resolution scan of a message written preferably with some kind of felt-tip pen.

Circle shaped symbols start and close in the upper center.

Plus symbols are heavier/thicker/darker on the right and/or bottom sides, this is consistent with the way the line symbols are drawn as seen a couple of posts back. I marked only a few examples just to give the idea of where to look. Of course you can also see darkening in the middle of the symbols as this is where the lines crossed.

Hi, Jarlve,

this is really a very interesting investigation. I think it’s very important to know how z340 was made. However, I must disagree with you in your conclusion. I think the strokes were drawn the other way around. Take a felt pen and try it out on a piece of paper. Especially if it is a very wet felt pen, a small drop forms as soon as you have finished a line and lift it up again. Here is an example (strokes drawn from left to right):

Thank you for adding to this topic Largo and I agree with your finding.
