how PCB is translated onto a plastic board?

Hi

I was wondering that how a real PCB is manufactured. The link #1 is a circuit design and #2 is its PCB layout. Are there some special kind of printers which are used to print the PCB design on a plastic sheet.

Here is a great article describing a tour of a US based PCB manufacturer. They go into great detail on how the boards are made.

Way back when, when there weren't PC's they layouts were TAPED at 4X using red, blue and black tape. The camera to make the mask was "walk in". Kinda cool.
