Line Name In Perf?

HI folks, I've been scouring the internet and this forum for a while, but keep coming up with the wrong answer. Take a look at the awesome Zeppelin pic I attached.

What exactly is the vertical line on the right perf called?
And more importantly, does this decrease / increase / not affect the stamp value.

For me, I like to see it because at least I can assume the perf on the opposite side is real.

Any thoughts?

Thanks so much!

Brian

Hi,
Line on the right side means that sheet was produced with four pains or two pains, these four pains was divided by cutting guide line horizontally and vertically. So we can guess that your stamp comes from left top or bottom pain as guide line for right side would be on opposite side.

The coil pair shown is a joint line pair. It is produced where the curved plates come together. Ink gathers in the joint and is then printed. It is not the same as the guide line on the Zeppelin stamp. That is a deliberately printed line to aid in the cutting of the large sheet into panes.

rohumpy @ Ok, ok, it was just an example, as I said its just a cutting guide line

rohumpy @ I found a better pictures, hope they explain better.

Here is the layout

In my humble opinion , it does not detract from the value.

It should not affect the value, rather it would make it a bit easier to plate this stamp! I notice a small plate variety on heybrian's stamp. Under the "st" of postage is a small what looks like a circle. Hard to see though!

Usually, imperforate straight edges occur along this cutting guide line on flat plate stamps and these straight edges are perforated by those who are trying to remove the straight edge especially for those edges where the line has been trimmed off to make it look like it was never a straight edge. Do these stamps usually have straight edges along the perforator cutting guide lines? Could perforations have been added on the right side to remove a straight edge? (O.K. I just read somewhere that since these stamps were issued in panes of 50 stamps instead of 100 stamps, they do not have straight edges like regular flat plate issues.)

That thing is scary gorgeous.
