I'm not sure what you mean by "side by side of the elements". The Photoshop Elements routine that was used just tries to break the image apart along what look (to a Photoshop software programmer) as lines in the jpeg. I don't think there is anything meaningful to be learned by that. But I could be wrong.
As to Post 1482 I have looked at that part of the Australian BC in Photoshop. There is no doubt that the printed "Deputy" looks like it is a layer above the a signature layer that was not blended properly nor merged properly. This would be pretty good evidence of a fake if it weren't for the fact that the signature is clearly on top of the printed word "registrar". That's very strange. The "Deputy" looks as fake as it can be. And "registrar" looks good as gold. Go figure. I don't know what to make of it.
The Y crossing over the D is explained away as the inverted dark black being stronger than the inverted lighter Y. It’s similar to a grey pen being written on white paper and crossing a black line. When inverted, the grey will appear below the now white line because the black can’t get any blacker. Same principle applies.
Take the Deputy Registrar part of the Bomford B.C. and enlarge it up to 600 percent. You can clearly see the entire block outline of that particular layer in contrast to the surrounding pixels.
