For the 2D photoplotter, its Gerber format; each is a variant of each other, but have become estranged over time. Many PCB prototype houses print the resist on the PCB, (usually with ink-jet technology.) The machines are expensive and the ink resist is not cheap, (but its available out of Japan in Cannon cartridge format, for certain Cannon printers.) Another alternative is to swap the white LEDs in an overhead projector with UV LEDs. But one would have the expense of positive photoresist, or still struggling with getting negative film to stick, which doesn't help much.
