inkjet printing

I know there have been several discussions about this topic before. I'm curious cause I've ran into the same problem.When printing to transparencies the ink somewhat beads up and solid regions of black are not close to being completely black. I used this before and it worked for my purposes but I wasn't using 10mil traces and I don't recall it being this bad. Its about 10% transparent in solid regions.I've read in previous posts that maybe using tracing paper, pen plotters, or commercial printing services is the better option and I will probably end up doing that if I can't come up with a satisfactory solution.Anyone have any ideas to improve the the distribution of ink? I was thinking about maybe scuffing the transparency a little to prevent beading up but this might effect the transparency somewhat or introduce distortions into the routing? Or could one heat up the transparency a little, maybe with a hot air gun but far away on low temperate? I imagine that idea would ruin any fine detail though.Jon

One site that disscussed laserjet printing the etch resist image directly to copper board said it had been tried but with poor results and the failure was hypothesized to be a cosequence of how the toner is distributed by electrostatic charge where the conductive surfaces may interfere with that process ?

Yes... I tried to fix that and the toner fusing problem due to the copper acting like a heat sink.

I coat my flex material before running it through the laser printer. I'm keeping that coating a secret for now in case I perfect it and want to profit from it someday.
