At last, I had the MkVII mock up printed and I am so happy that they fit. I started on the Artwork using version 0.92 of Inkscape many years ago. And when I resumed work in 2019, there was some issues with the resolution of 96 dpi. It happened after I upgraded the software to version 1.1
Anyway, after solving that issue, I had to redo the artwork. That gave me the opportunity to literally start from scratch. Today, the design fits except for some 1mm width error on the middle of the large decal near the screen.
The mock-up lies on top of the previous work which is the Avery Paper. You can see the difference in the output quality as the Avery Paper was printed somewhere in 2017, on a large format inkjet which was meant to be seen from a distance.
