Thanks to Rick, here's the result of my second test roll
Firstly, I'll like to thank everybody for the many helpful advice that I've received on this thread, especially Rick, who provided me with his workflow.

I can also conclude that "light leak" was not a cause of the imprinting of the numbers since I did not have that problem here. It's more likely caused by the reasons pointed out by Simon.
Once again, many thanks to all and I'll post a "real" shot soon :-)
