some objects not printed as to seen in the image - why?

[Holger]

Thank you very much for helping me!

I have insert now two additional images: numer 1 is showing how it looks on my screen and numer 2 is a scan of the printing result.

Concerning the background: I would like to have a vintage paper background and do not know how to make it with that plasma cloud fill. But I will look for a higher resolution paper background.
