Hello, Some geeks and myself are talking about making some moderately advanced circuit boards. I was thinking back to the plotter idea, where you use a XY plotter to plot directly onto the PCB surface. This seems nice, and should yield a quicker turnaround versus the iron one blue toner transfer stuff. But I have a different idea. What about modifying an inkjet printer to print directly on the board. Will the ink resist the etchant like a sharpie marker will? People have modified inkjet printers to print on CD-ROM disks, so I'm assuming it can't be that hard to mod one of these printers, but the value would be the question. If a marker could be had for a X-Y table pen plotter that could do 1mm tracks (surface mount devices are the goal here) then that would be acceptable. Help and tips appreciated!
