Default Re: UV Dry Film PCB technique - experiences to date.

Epson have tended to prefer pigment based inks. Canon, HP have mostly used dye based inks. This might explain what you've found.

The pigment inks are highly rated for life expectancy of photographic prints, but they can be devils for print-head blockages.

Many of the HP printers used to have the print head integrated with the ink reservoir, so you fitted a new head with every refill. Today, they're more mainstream.
