This is wonderful !
I spent seven years to see something like that.
I think, that the next step would be use a polygonal mirror. Maybe, trying to modify a laser printer.

There is no problem to print 1.4/1.4 mil width and space but development of the dry film is a little bit problematic and it is not possible to do it with simple tray technique. The film that I'm using has a thickness of 1.5 mil, according to some google results the limit is 1.5∗film thickness, so if it is true it seems my results are almost at the limit.
