Thanks for the reply's so far.
While waiting, i did tackle the halftone part..
I thought there was no halftoning in this, but i was wrong
Anyway, its a small one that i can copy and copy and then again copy
The original:
Calculated the same distance and placed some guides..
Cut the holes out, and Presto !
looking at it again, i might have better used a bit bigger dots..
well its 3 cm wide so no-one will notice it in the end i think
