HI
just make my first test on the Xerox solid ink printer
(collor-cube 8570n)
that was shame , noting close to 2400dip claimed by xerox
this was same pcb image print wit dell laser printer (600DPI)
and whit the Xerox for comparaison (transparency over white sheet)..
http://www.alphatronique.com/XEROX.JPGhttp://www.alphatronique.com/dell.JPGonly good thing is that black was really black
this was also image from Xerox print on paper of a QFN 0.5mm pitch
http://www.alphatronique.com/tqfp.JPGsome trace close up ...
http://www.alphatronique.com/trace.JPGso i still need to find a better printer once again
Best regard
