Can ink be used to trace a PCB for etching?

I will be making lots of PCBs. I have access to silk screen shop. I was wondering if there is a type of ink or paint i can silkscreen the traces with, rather than using positive coated boards, which cost more.

sharpies work well as etch resist ink and so do laser printers.... for sharpies, simply hand draw the connections as for the laser printer, there are instructables out there for the tonere transfer method where ur layout will be printed mirror image on a laser printer, and then the toner will be transfered onto the pcb with an iron hope this helps...
