3-M has/had a method of photographically marking anodized aluminum.
Silk screening (on virtually any substrate with the proper ink).
Both methods will work from a film original, which you can create
by any number of means. I've used a combination of algorithmic and
WYSIWYG (for non-critical markings) methods with success. Some
markings (not divisions) on some kinds of dials are not suited to
simple algorithmic placement for artistic reasons.
There are also engraving methods (very suitable for one-offs) and
photochemical etching. Laser marking can be used for small
quantities, however the equipment cost is substantial. It's one
of the production methods of choice.
