Another thing to prevent mistake is to have a builtin list of common
processes. Like 0.35mm copper, 0.3mm gap, 0.2mm silkscreen. That's used
very often. If you enter one of those numbers wrong you can throw the
board away often.
This is part of the reason for the vendor resource file support in pcb.
It lets you define vendor capability in a single file which can be
loaded in. It should be a simple task for you to capture the
requirements of your particular vendor in that file.
