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.

Wow.

Any chance you would post a picture of the machine that did that work?

Or of how much it costs to make?
