There are a few other 100% 10 micron FM in North America - but these two I know for sure.
I don't know of any printer who can charge extra, nor customers who are willing to pay more, for jobs printed using FM or other very fine screens. Instead, it is used for competitive advantage and manufacturing cost savings.
Dear Gordo,
Thanks,
I am of the opinion, since the effort to print 10 micron is much more than 20 or 25 micron and it does give the customer an advantage there should be a premium to it. But this is for the individual to decide.
