You could use IR printer which has a resolution of more than 10000 DPI.
Offset Printers who make the master copy usually have this printing
facility.

With this we at I.I.T. Bombay have been regularly using this technique for
mask making and getting reliable results upto 5 microns.

Wish you all the best.
