Direct to PCB InkJet Resist Printing (2006)

This page details the use of Epson^ InkJet printers with based inks to feed and directly print resist patterns to copper clad printed circuit board stock, ready for etching. And if you admit that a laminator is required for TT, given the prices for old C84^ or R220^ / R280^ printers and the Inks, direct to PCB InkJet printing is cheaper. The Epson InkJet printer use pizeo electric actuators in the print head (rather than the thermal method used by other brands) which allows for a wider range of ink types to be squirted out.
