I've always wondered how they paint on the colored stripes. I put "how
do they paint the stripes on resistors" on google, but all I got was
links explaining how to READ color codes.

Has anyone ever heard anything about this process?

Isn't it obvious? Early resistors were hand painted, then they
developed machines for the job.

It's a no brainer they use a machine. My question goes much deeper. How
does the machine do it? Are the paints applied by a paint brush, or
something like a felt tip marker, or maybe some sort of spray method?

You really think a spray would be a good match for this app?

Once the correct colors are chosen for that batch of (whatever value),
how do they rotate them

seriously?

so the paint is not smeared. I can only assume
they are picked up by their leads, not the body, and somehow rotated by
their leads too.

good luck in life.
