I would agree with Sr Tech..Grid lock and systems like this can be used on the Ekra, MPM and DEK printers also can be used in Pick and place depending on the density of pin. If you choose the method of printing out a 1:1 photoplot. Glue it to a piece of Lexan and make the Lexan the same size as the board. Again you can also use this in a pick and place for placement of parts. I guess it all depends on $$$$$$ available and type of job. I tend to favour the other methods. They do not damge or move the components.
