For your feeding problems, place a strip of white tape at the leading edge of the transparency. That will activate the opto sensors so it will feed normally.

Ah so that's what it is. Good luck with your build.
OK, after throwing all the toys out of the pram, and spitting the dummy, I jumped out the pram, picked the toys up and sucked on the dummy again.
My perseverance is paying off. It's just amazing how much the settings affect the print density. Went to Epson Matte paper choice and things improved, but still a lot of pinholes. Turned off high speed and density increased further. Found some slider bars for density and contrast and set them to max, now pinholes just about gone.
Holding the transparency up to a very bright compact fluoro light and I can just see the light through the black but compared to the non printed clear areas the intense brightness of the light hurts my eyes. I'm guessing the black is going to block the UV enough.
The worst problem I'm having is feeding the transparency with the white paper attached. I keep getting paper jams. So now my quest is to find another printer which can detect transparenies, and I'll fill all ink cartridges with some of that special super black ink that's been mentioned. Then that will be the dedicated PCB making printer.
