Hi ST. 

I agree, i feel the small sprinkle of toner will not transfer. If they do, they will probably etch away. But the lines themselves just do not look that clean/sharp. I was wondering if I was just getting to a practical limit of the toner or if my settings might need tuning. I mean, 4mil and 6mil are very small anyway. I do not even need them right now but boundaries are there to be pushed and it interests me to see what can be achieved and what can be achieved reliably. 

I wondered if the normal paper also does not collect the toner agreesively enough. Maybe there is better paper. I have some toner tranfer paper bought from Pulsar but do not want to waste too much of it at this stage. i did print a little on that and it seemed to look very similar to that of plain paper.
