isn't this done by silkscreen printing?
all i know a about this is that you have a screen which is coated with photoresist.
this has to be exposed pretty much like a pcb.
then you can apply the color from the top (with a roller??).
this can't be too difficult if you can get the material.
i know of people having done t-shirt printing this way.
as you are in .ch:
http://www.altesspital.ch/i_werken.html they have "siebdruck" equipment, maybe try to ask them where
they get it?
there are (quite big) screens at ebay.de for two additional days from now... maybe have a look.
i found something much better: (more familiar)
there is also a optical method:
http://www.peters.de/saved/ref149d.htmi assume you speak german.
in principle it is applying a laquer and then exposing it.
afterwards the unwanted parts are developed off with sodium carbonate or alcohol.
then it is hardened.
seems quite simple.
as i don't want to make this (no need) i don't search further. please tell us if you find better
descriptions/sources.
